Re: [one-users] onevm saveas, "ID not defined"

[Carlos Martín Sánchez]

I'm still unable to replicate the error here...

Could you check (or send) oned.log file? The problem may be related to the
DB initialization.

Re: [one-users] Managing VMS with Script

[Carlos Martín Sánchez]

Hi Siva,

The VMs will staty in shutdown until they are, well, shut-down. If your VMs
don't answer to the acpi signals, OpenNebula will keep waiting.
Your machines are shown in onevm list because they are stil running (you can
check if they are visible in your hypervisor).

Keep in mind that a graceful shutdown is different from a delete command,
that may be what you are looking for.

Re: [one-users] Placement section

[Carlos Martín Sánchez]

Hi Rubén,

The PLACEMENT attribute you are using is ignored by the scheduler (take a
look at the examples in the link you provided). Try with
REQUIREMENTS = "HYPERVISOR   = \"kvm\""

If you are using the development version, you may want to try the new host
clustering feature [1] instead of using the hypervisor attribute.

Carlos

Re: [one-users] Is APIs of ONE 2.0 compatible with ONE1.4?

[Carlos Martín Sánchez]

Hi Xiaoyi,

Currently you can interact with OpenNebula 1.4 using our ruby, java and
XML-RPC APIs.
Applications developed using this 1.4 APIs will be compatible with the
upcoming OpenNebula 2.0, except for the new introduced functionallity.

Regarding the bug you report, you are right, it should call the "restart"
action. Thank you for your feedback!

Best regards,
Carlos.

Re: [one-users] Status of the java bindings

[Carlos Martín Sánchez]

Hi Tiago,

The current Java API is 1.4 compatible, and that makes it also compatible
with 2.0, except for the new functionality.
We are going to update it, but most probably not until we have the final
OpenNebula version finished.

It has to be updated for the new methods one.vm.savedisk, one.user.passwd,
and all the new methods for image and cluster management. You can check all
the details at the XML-RPC documentation for 1.4 [1] and 2.0 [2].

Carlos

Re: [one-users] Persistent Storage

[Carlos Martín Sánchez]

Hi Flávio,

One of the new features introduced in the 2.0 version is the Image
Repository [1]. If you want to give it a try, you can download the RC1 we
have just released today [2].

Using this repository, you can create an empty DATABLOCK image to store the
data you mention. The changes made to the image are saved back to the
repository once the VM is shutdown; and you can then then mount that image
in any other virtual machine.

You will find useful the documentation for the new oneimage command [3], and
the saveas option [4] for the onevm command.

I hope this meets your needs. If you need any more specific help, let us
know.


Best regards,
Carlos

Re: [one-users] Sparse Images with 2.0

[Carlos Martín Sánchez]

Hi Frank,

You could modify the core to make it keep the SIZE sub-attribute in the DISK
attributes, but that seems rather complex for what you need.
It looks to me that the best approach would be #2, considering you have
already your custom transfer scripts. You could just add a new attribute,
something like

DISK = [ IMAGE = "imageA" ]
DISK_SIZE = [ DISK_ID = 0, SIZE = 1024 ]

DISK = [ IMAGE = "imageB" ]
DISK_SIZE = [ DISK_ID = 1, SIZE = 2048 ]


Or a more readable option

DISK = [ IMAGE = "imageA" ]
DISK_SIZE = [ IMAGE = "imageA", SIZE = 1024 ]

DISK = [ IMAGE = "imageB" ]
DISK_SIZE = [ IMAGE = "imageB", SIZE = 2048 ]


Regards,
Carlos.

Re: [one-users] OpenNebula 2 RC: Why do image names have to be unique?

[Carlos Martín Sánchez]

Hi Carsten,

Yes, it is necessary if you want to be able to use the image name's in the
template, like

DISK = [ IMAGE = "Ubuntu Lucic" ]

Otherwise, you are forcing the users to use images by their IMAGE_ID, which
is an internal ID that can change at any time, e.g., you define templates
for your IMAGE "Ubuntu" and a VM that uses "Ubuntu", but the VM template has
be modified if you delete and register again some time later that IMAGE)

Re: [one-users] vm creation failed

Hi Juan Luis,

You are using the "type" attribute for your second DISK wrongly, take a look
at [0].

Let's try with this instead:

DISK   = [
  TYPE = swap,
  SIZE = 1024,
  READONLY = "no"
  TARGET   = "sdb"]

Re: [one-users] deployment file doesn't get generated properly

[Carlos Martín Sánchez]

Hi Rich,

I think the problem is that you need to set a TARGET attribute for the
second disk, because OpenNebula will only assign one for the Disks that use
a registered IMAGE.
If you take a look at [1], the TARGET is mandatory. Since you are mixing
Disks that use Images with Disks from your filesystem, you should pay
attention at the "Disks device mapping" section to avoid target conflicts.

Or you could just register your .iso file as a CDROM image.

Regards,
Carlos.

useful indeed.

I have opened a ticket [1] for this feature, but meanwhile you could change
the connection call in src/sql/MySqlDB.cc, line 39. That method is
documented in [2].

Thanks for your feedback,
Carlos.

Hi Federico,

The documentation of the DB schema is on its way. I'll post the link in this
thread when it's done, hopefully later today.

Re: [one-users] putting OS images in the image repository

[Carlos Martín Sánchez]

Hi Steven,

This is an interesting use-case. When we designed the image repository, we
had to make a compromise between "expectable behaviour" and "advanced
customization usage". I guess this falls into the advanced usage, but
OpenNebula is flexible enough to take this challenge.


To automatically save all VM disks that use a certain Image, you can use
hooks.

I would add a new flag to all the relevant images in your system, either
having them in the image template, or adding them afterwards [1]:
oneimage addattr  AUTO_SAVE YES

This will add the flag to the template:

$ oneimage show 1
IMAGE  INFORMATION

[...]

IMAGE TEMPLATE

*AUTO_SAVE=YES*
DEV_PREFIX=hd
NAME=test_image
PATH=/home/cmartin/trabajo/scratch/steven/disk.img
TYPE=OS

To add a new hook to the system, edit $ONE_LOCATION/etc/oned.conf [2] and
add something similar to the following:

VM_HOOK = [
name  = "auto_save",
on= "CREATE",
command   = "auto_save.rb",
arguments = "$VMID" ]

This will execute a new script, placed in
$ONE_LOCATION/share/hooks/auto_save.rb, every time a new VM is created.
I suggest you to use ruby, because the ruby OCA API [3] will make it easier.

This script will have to:
1) Get the complete information for VM  from OpenNebula.
2) For each disk, check if it is using an Image.
2.1) Get that image's information, and look for the AUTO_SAVE=YES attribute.
If it's present, then issue a onevm saveas operation over that  and
.

To be able to identify the disks later, you could include in the new image
name the  _ string.


This way, files will be all managed by OpenNebula in the repository. If you
are doing this for back-up purposes, and you won't actually instantiate a VM
using this saved images, you can always move that files away from the
repository and then delete the images.


This is the easiest and "elegant" way I see to do this, but any
other opinions are welcome.

I'd also like to ask the community if more people feel this should be
supported out of the box by OpenNebula. If so, we could start a discussion
to determine the specific features or requirements this would imply.


Best regards,
Carlos.

You may want to ask about it in the ecosystem mailing list [1], but as far
as I know the Management Console [2] is only compatible with OpenNebula 1.4.
The EC2 Query API tools [3] are a user-oriented alternative, you can give it
a try and check if it suits you needs.

 The creation of images (of OS) must be done through an external tool (like

The actual virtualization will be performed by the hypervisor of your
choice, so you can use any available tool for it.
But it is not mandatory, you can create them using only OpenNebula (creating
blank images, where you will install the OS form a cd-rom iso).

This was true for 1.4, but in OpenNebula 2.0 the Image repository [4] was
introduced; and now you can let OpenNebula manage your image files.

That's the preferred way, yes. As a reminder, the contextualization guide is
documented in [5].
There was an interesting thread some weeks ago about using DHCP instead, you
can check it in the list archives [6].

Re: [one-users] OpenNebula 2.0.1 sets incorrect ARCH.

[Carlos Martín Sánchez]

Hi John,

The ARCH  can't be defined in the Image templates.

We are considering a new feature that will let you register VM templates in
a VM catalog, to be instantiated easily just using its name or ID. This way
you will be able to register at the same time the OS image and the VM
template that uses that image.

Would this fit your requirements?

 I just installed 2.0.1 on a machine which now seems to set the ‘arch’

 ‘i686’, the correct value for my system is ‘x86-64’. How does OpenNebula
 determine the value it sets (I use kvm with Ubuntu 10.4 64Bit as OS and in
 the VM)?

Re: [one-users] Detecting potential failures earlier

[Carlos Martín Sánchez]

Hi Steven,

Thank you for your feedback, we will definitely take your suggestion into
account.

For future releases, we are planning to develop a VM templates repository.
The templates could be checked for frequent errors and missing mandatory
attributes before being saved into the templates pool.

Because this feature is still in the design process, ideas and comments are
more than welcome.

Regards,
Carlos.

Hi Idafen,

At the moment, OpenNebula can only use Sqlite or MySQL databases as backends

But there are not any restrictions for the software you run inside your

When OpenNebula is installed, the images directory is set up with the sticky
bit. From install.sh:
chmod 3770 $DESTDIR$IMAGES_LOCATION

In [1], it says


"The IMAGE_REPOSITORY_PATH can be changed to another administrator defined
folder. This folder will need to be created with special permissions to
ensure its consistency. It will need full permissions for writting new files
for any user, and:

* the sticky bit, so other users are allowed to read other user files, but
aren't allowed to erase them
* the setgid, so all the files copied to the image repository end up with
oneadmin group

This can be achieved with “chmod 3770 /path/to/image/repository/”."


If you changed the images path, or if for some reason you deleted the var
directory, you'll need to recreate the sticky bit configuration.
In order to let other users register images, you have to either let anyone
write in the images path, or add all your OpenNebula regular users to
oneadmin's group.

Could you please check your configuration? If you continue having troubles,
please send us your installation directory permissions.

What's your goal? to control it somehow in the VM template, or rather create
a new command such as:
oneimage clone "Original_public_image" "My_private_copy" ?

We agree. Actually, that functionality is already in our roadmap for

Re: [one-users] onevm create/deploy commands to send VMs to host of our choice (OpenNebula 2.0.1 and CentOS 5.5 with Xen)

[Carlos Martín Sánchez]

Hi Prakashan,

There are different options to control the placement of the VMs.

If you want to manually deploy them, you can hold the VMs (onevm hold ).
The scheduler won't place these machines, but you can still deploy them with
onevm deploy.
Or you could start only the OpenNebula daemon without the scheduler (take a
look at the 'one' start script, and comment the ONE_SCHEDULER part).

The other option is to use the REQUIREMENTS and RANK VM template attributes,
see [1].
The scheduler will read them, and place the VM accordingly. You can require
the VM to be deployed in a specific host or cluster; or modify the RANK
expression to set the hosts priority.

Regards,
Carlos.

Re: [one-users] VM Life-Cycle

[Carlos Martín Sánchez]

Hi Taylor,

The save state is an intermediate state, in which the VM's state in being
saved. After that is completed, the VM should change to the "suspended"
state.

If the VM is stuck in the "save" state, you should check the logs for any
error. Please check oned.log, or VAR_LOCATION/http://dsa-research.org and blog

Re: [one-users] 'onevm saveas' via XMLRPC or OCCI???

[Carlos Martín Sánchez]

Hi Marco,

The XML-RPC call requests an image id because the image has to be created
beforehand.
You can check how it is done in the oneimage command (it's a straight
forward ruby script), and then replicate the same steps in your code.

Regards,
Carlos.

For version 2.4 we are going to move all this image files management to the
Core Daemon; we hope that will make things easier for upper layers, as you
suggest.

Re: [one-users] bug in image.rb HOOK? ('onevm saveas' command)

[Carlos Martín Sánchez]

Hi,

If I'm understanding right, you first log into your VM, shutdown it
yourself, and then issue the "onevm shutdown ".
Is this right?

onevm shutdown command assumes the VM is still running, and sends the ACPI
signal to the machine. Your virtualized OS is supposed to shutdown itself
with this shutdown signal.

If the VM Life Cycle is managed manually, OpenNebula will lose track of what
happened, that's why the VM is seen as UNKNOWN.

Regards,
Carlos

That's right, OpenNebula assumes the VM Life Cycle is managed exclusively by
itself.

If you want to be able to take the decision to shutdown the VM from the
virtualized environment, you would have to make it contact the front-end
where OpenNebula is running and use the command 'onevm shutdown '

Carlos

Re: [one-users] Why not a "support forum"?

[Carlos Martín Sánchez]

Hi Luigi,

Thank you for your feedback. We are aware that as the threads volume
increases, navigating the archives and locating specific info can be
challenging.

We'll take your suggestion into consideration. We could aim for a hybrid
approach, keeping the mailing list and somehow integrate it into a forum.
Actually, you can use gmane [1] to navigate our mailing list in a forum-like
style [2].

Hi Nikolay,

Could you paste the output of

?

Change /var/tmp/one to your SCRIPTS_REMOTE_DIR if you changed it in your
oned.conf file.

Hi Nikolay,

Take a look at these C++ files:

Re: [one-users] can oneadmin (uid=0) create a VNET that is owned by another account?

Hi,

That's a functionality we definitely want to add to OpenNebula, along with a
more advanced user management see [1]. We've opened a ticket with you
request:

Re: [one-users] help understand one_xmlrpc.log

[Carlos Martín Sánchez]

Hi Shi Jin,

That log is created by the xmlrpc-c library [1]; so not so helpful
information about OpenNebula itself is logged.
The Request Manager component logs are written in oned.log file. We could
move that logs to a separate file with extended information if the community
think this is needed.

Regards,
Carlos.

Re: [one-users] cannot have two VNETs created by uid=0 on a single VM by another user

[Carlos Martín Sánchez]

Hi again,

I haven't been able to reproduce the error, in either one 2.0 or 2.2
branches. Unless all vnets are public, the authorization rejects the new VM.

On the other hand, we may have confused you with this documentation quote:
> Virtual Networks created by oneadmin can be used by every other user.

That was how VNets were shared in OpenNebula 1.4. Since 2.0, oneadmin's
VNets are shared using the 'onevnet publish' command, just like any other
user's. The guide is now fixed, sorry for the confusion.

Regards,
Carlos.

Re: [one-users] can't delete host

[Carlos Martín Sánchez]

Hi all,
This problem was identified [1] and fixed for next releases.

Meanwhile, you can use the hack Zaina pointed to. It is safe to delete the
host with the negative counter, the DB consistency won't be affected.

Re: [one-users] RPC client: how to determine my user id?

[Carlos Martín Sánchez]

Hi Carsten,

You can use instead the -1 filter flag [1].

The user ID is intended for administrators. Authorized users like 'oneadmin'
can perform a one.userpool.info call and look for the ID of a given name.

Regards,
Carlos.

Re: [one-users] RPC client: how to determine my user id?

[Carlos Martín Sánchez]

Hi Carsten,

You are right, there are some operations that require the user ID and only
oneadmin can know it.
For now, those operations will remain only accessible to oneadmin. In the
short term, we want to improve the overall user management (to add groups
and, maybe, permissions) and we'll address this issue at that moment.

Thanks and regards,
Carlos.

Re: [one-users] FW: XMLRPC Configuration

[Carlos Martín Sánchez]

Hi Joe,

The XML-RPC interface requires the contents of the template to be included
as a string parameter, not the template path.
You can place it anywhere your client application can read it.

Re: [one-users] command to deploy VM on remote host

[Carlos Martín Sánchez]

Hi Nikolay,

You can check (and customize) the vmm_mad script files for each hypervisor
in your $VAR_LOCATION/remotes/vmm dir.
If you modify these scrips, use 'onehost sync' to update the files in the
remote hosts.

e.g. for Xen and system-wide installation, check
/var/lib/one/remotes/vmm/xen/deploy (and xenrc).

Regards,
Carlos.

Re: [one-users] what's the exact meaning of CPU in vm template file?

[Carlos Martín Sánchez]

Hi Xie,

Both are true for Xen, for other hypervisors only 1 applies.
Regarding 1, the VM won't be deployed by the scheduler, but you can still
force the deployment manually using 'onevm deploy'.

Carlos.

Re: [one-users] Virtual networks by static leases.

[Carlos Martín Sánchez]

Hi,

The behaviour you are describing is not the intended one, OpenNebula should
never generate a random IP. It will either get one of the free Leases from
the requested VNet, or return an error.

Could you copy the VM templates you are using? At least the NIC attributes.

Regards,
Carlos.

Re: [one-users] Call "one.image.allocate" of xml-rpc API question!

[Carlos Martín Sánchez]

Hi,

As you pointed out, your client program has to copy or create the file, and
then enable the image.
The command oneimage already does that. You may want to check it (the binary
executable is actually a ruby script) and ImageRepository.rb

Re: [one-users] Fwd: Error trying to CREATE HOST Error inserting Host Share in DB

[Carlos Martín Sánchez]

Hi Vivek,

You are installing OpenNebula 2.0, right?

Could you check if there is any error message in oned.log right after this
message?
[ONE][I]: Bootstraping OpenNebula database.


It may be also helpful if you could send the output of
$ sqlite3 one.db ".schema"

Re: [one-users] vm fails to start - vm.log: [TM][E]: prolog, error getting driver vmm_kvm

[Carlos Martín Sánchez]

Hi Marius,

Please check in oned.log if right after start-up there are some error
messages like:
MAD did not answer INIT command

If so, you can enable the mad debug in etc/defaultrc: ONE_MAD_DEBUG=1. That
could shed some light on the issue.

Regards.

Re: [one-users] Can't restart or resume VM when VM is in save status. And MEMORY = 0 when VM is running .

[Carlos Martín Sánchez]

Hi there,

If you take a look at the Virtual Machine Life-cycle diagram [1], the 'save'
state is a intermediate state, and the VM should end in either the
'suspended' or 'stopped' state. If the VM is stuck in 'save', you may find
some error messages in oned.log or the VM's log (in /vm.log).

About #2, it may be a monitorization problem. Can you check using virsh or
xentop the actual memory consumption?

Best regards,
Carlos.

That's the normal behaviour, VMs in DONE state are not listed. However, you
can still see the extended information using 'onevm show ', because they
are stored in the DB for accounting purposes.

Are you using the Image Repository [1]? If so, is the Image persistent?
If you are defining the DISKs in the VM templates as in previous versions,
make sure the attribute SAVE=YES is present.

Re: [one-users] Can not SSH ttylinux

Hi,

The first thing you should try is to open a VNC session [1] and check if the

If that's not the problem, then this FAQ entry [2] may help you to find a
network configuration problem.

Re: [one-users] how to predeploy image

[Carlos Martín Sánchez]

Hi Łukasz,

You could use the tm_dummy driver. That tm script returns always 0 and does
nothing else.
But using that tm_driver, you will have to manually move the files for all
VMs, not just some of them.

It would be best if you could modify the driver (tm_clone.sh, look for it in
your lib location) to issue the mkdir and scp commands only if the
destination file is not already present. It should be pretty
straight-forward.

Regards,
Carlos.

Re: [one-users] Fwd: Error trying to CREATE HOST Error inserting Host Share in DB

[Carlos Martín Sánchez]

Hi Sebastian,

Any other error messages? What about the bootstrapping section of the log?
Try that sqlite3 command (assuming you have sqlite set in your oned.conf) in
/var/lib/one; or $ONE_LOCATION/var if you installed it in self-contained
mode. That's where you'll find the one.db file.

On a side note, if you are using localhost as front-end and Host then you
can use the tm_nfs drivers, since the FS is shared.

Regards,
Carlos.

Hi,

Do you have a registered image called "ubuntu_desktop"?
Is it in ready state?

Re: [one-users] RPC client: how to determine my user id?

[Carlos Martín Sánchez]

Hi Carsten,

I just wanted to let you know that we have implemented an XML-RPC method
one.user.info, that can be called with -1 to know all your own user
information.

You can follow the development here:
http://dev.opennebula.org/issues/552

Regards,
Carlos.

Re: [one-users] Problem monitoring Xen host 2.2

Hi Javier,

Maybe the dom0 is taking all that memory. Take a look at this thread:

Re: [one-users] setting variables ONE_LOCATION

[Carlos Martín Sánchez]

Hi Marco,

If you installed OpenNebula from the packages, then the installation was
made in system-wide mode [1].
You don't need -actually you shouldn't- set the ONE_LOCATION env. variable.

Re: [one-users] user permissions on vnet

[Carlos Martín Sánchez]

Hi Ignazio,
This is a quick change to the simple_permissions.rb script. I didn't even
check if this works, but it should help you get the idea of what Daniel
proposed.

When modifying an authorization script, you have to take into account that
oneadmin (user with id = 0) is granted anything in the core.

Re: [one-users] Directory structure under $ONE_LOCATION after install.sh, lacks several folders

[Carlos Martín Sánchez]

Hi Luis,

If you use the -c option of the installer, only a minimum set of client
files are installed.

Regardless, the directory trees in the link you provide have to be updated.
Meanwhile, this is what a 2.2 self-contained installation looks like
installing only client utilities (-c):
$ tree -d
.
├── bin
└── lib
└── ruby
├── cloud
│   ├── econe
│   └── occi
└── OpenNebula

And a regular self-contained installation:
$ tree -d -L 2
.

│   ├── auth
│   ├── ec2query_templates
│   ├── hm
│   ├── im_ec2

Re: [one-users] Does the SOURCE make no sense when creating an image in opennebula-2.2.0

[Carlos Martín Sánchez]

Hi,

You are right about the steps made by the ruby OCA and OpenNebula daemon.
And indeed, it makes no sense to specify only a SOURE attribute *if it is a
file path*.

But you can still take advantage of the SOURCE if you use an http:// url.
This can be used to bypass the local Image Repository and store some of the
Image files remotely.

Anyway, this isn't the typical scenario, and maybe it still makes sense to
remove the SOURCE option from the Suntone wizard.

Best regards,
Carlos.

Re: [one-users] how to disabled a user?

[Carlos Martín Sánchez]

Hi,

The 'enabled' attribute for users had a meaning in previous versions.
But right now I think you can just forget about it.

We'll check if it is safe to remove it completely in the next releases.

Carlos.

Re: [one-users] Regular user can not register on opennebula

[Carlos Martín Sánchez]

The same way you can't just register yourself in a Unix system.
Sunstone is not aimed for final public cloud users, it is a control panel
for OpenNebula.

Re: [one-users] There has no parameter to define subnet mask in Virtual Network template.

[Carlos Martín Sánchez]

Hi,

You can define any extra attribute, like NETMASK, in the Virtual Network
template when you create it.
Those attributes can be accessed within the VM using contextualization. In
[1], there's a brief example with a DNS field.

Don't forget to make your vmcontext script do something useful with that new
attribute.

Regards,
Carlos.

Re: [one-users] Java OCA: poor choiche of Exception class

[Carlos Martín Sánchez]

Hi there,

The RuntimeException looks better to me.

The only thing I'm not sure about is why you deleted the 'throws'
declaration from Client.java.
Doing that, a client application is not forced to catch the connection
problem.
I think it's better to force the coder to be aware of this kind of problems,
and prepare a nice error dialog, or a re-try mechanism.

What do you think about using the RuntimeException and
'public Client() throws OpenNebulaConfigurationError' ?


Best regards,
Carlos.

Re: [one-users] onevm saveas command

[Carlos Martín Sánchez]

Hi Prakhar,

The Java OCA is a wrapper for the XML-RPC interface [1].
The image file manipulation done by the oneimage command is performed by the
ImageRepository.rb [2] utility. You can take a look at the code to get an
idea of the steps. Or even check this thread [3].

Your Java application has to be aware of that, and perform the same file
operations, as described in [4].

Regards,
Carlos.

Re: [one-users] OpenNebula and authorization

[Carlos Martín Sánchez]

Hi Lars,

The functionality you are describing will be available for the next release.

Our first idea is to have a main group and many secondary ones for each
user; the rest of the resources will belong only to one group.
We'll implement an ACL system to allow fine-tuning of the permissions.


If you need to implement it for 2.2, I'd suggest a workaround in the
authorization module.

The VNET, Image and VM templates can contain arbitrary data to store group
information, but new data cannot be added once the resource is created (with
the exception of Images). So the resource-group association will be better
managed in an external DB, which shouldn't be problematic since all
OpenNebula resources are identified by a unique ID.

About the creation and management of groups, it could be done totally
independent from OpenNebula, as long as the data is stored in a DB accesible
from the authorization driver. If the driver is written in ruby, the sequel
gem can take care of both sqlite and mysql connections.

The main problem with this workaround is that users will be able to list and
see all resources, without a way to identify which ones are available for
them.
This could be tackled modifying the onevm, oneimage and onevnet commands.
Since these files are just ruby scripts, you could read your permissions DB
and add a new column to the resources table showing the group(s) they belong
to. Or even hide some of the resources.

For the external DB, sqlite should do just fine. I believe you can even
protect it setting the file to be read-only for the users executing the
onevm/oneimage commands, and writable for oneadmin.


Best regards,
Carlos.

Re: [one-users] having a problem when shut down a VM

[Carlos Martín Sánchez]

Hi,

>From the libvirt doc. [1]:
ACPI is useful for power management, for example, with KVM guests it is
required for graceful shutdown to work. If you set ACPI = YES, then your VM
should have the ACPI daemon running and be configured to shutdown with the
ACPI signal . For instance, I think Ubuntu Desktop shows the log out menu
instead.

Carlos

Re: [one-users] shutting down VM vs stopping it

[Carlos Martín Sánchez]

Hi Nikolay,

The life-cycle diagram [1] is the best way to understand the VM states, and
what actions are available for each of them.

If you shut down a VM, it will enter the final DONE state, from which no
action can be performed.
A stopped VM on the other hand can be later resumed, using 'onevm resume'.

Internally, the difference is that shutting down the VM it has a chance to
perform any operations (like unregister from a service). A stopped VM is
suspended (paused).

Re: [one-users] VMs still reported as running although host is down

[Carlos Martín Sánchez]

Hi Steffen,

There are two reasons I can think of that can cause that behaviour:

1) The next monitoring cycle hasn't been triggered.
2) The monitorization was triggered, but the command crashed and it didn't
return neither FAILURE or SUCCESS to the core.

I've made a couple of tests and found that, indeed, there is a bug :/
You can its ticket here [1].

The problem is that the core sends the monitoring request to the ssh driver,
and it is supposed to return FAILURE or SUCCESS. Instead, the driver is
crashing, and the Host and VM keep the last monitoring data (and status).

This could also cause trouble if the motorization probe gets stuck, and
doesn't end its execution.
We are aware of this problem, and we intend to add timeouts and checks to
the drivers to ensure that the actions are always answered to the core.

Thanks for the feedback!
Carlos.

Re: [one-users] How config Windows vm template?

[Carlos Martín Sánchez]

Hi there,

The contextualization offered by OpenNebula is creating that cdrom and
context.sh script, but it's up to the guest OS to read that file and
configure itself.

We only provide linux scripts; you would have to create similar ones. I'm
not sure how difficult that can be since I don't have experience with
Windows scripting.


If you only need to configure the right IP for your VM, then you can try to
configure a DHCP server in your network (it can be placed in a VM in the
same VNet). This has been discussed in the list, hopefully these threads
will help:

Re: [one-users] second argument for restore script

[Carlos Martín Sánchez]

Hi Nikolay,

We have opened a ticket with your request [1], to provide a generic method
to query any VM attribute from the drivers.

Meanwhile, you can add the deploy_id as the last parameter modifiying
src/vmm_mad/ssh/one_vmm_ssh.rb, line 81

-remotes_action("#{@remote_path}/deploy #{remote_dfile}",
-id, host, :deploy, @remote_dir, domain)
+remotes_action("#{@remote_path}/deploy #{remote_dfile} #{id}",
+  id, host, :deploy, @remote_dir, domain)

Carlos.

Re: [one-users] '-' or 'err' (instead of 0) as a value for parameters which ONE fails to get

[Carlos Martín Sánchez]

Hi Nikolay,

The memory and cpu are numeric attributes managed by the core, initialized
to 0.
If the driver doesn't report them, they are not updated.

The way I see it, the drivers didn't know how to populate the values, rather
than encounter an error monitoring them.
We could modify the core to initialize them with -1, and make the CLI show
'unk' or '-'.

But to me it makes more sense to report always a positive value, since the
data can be consumed by other applications, and dealing with the special
case of -1 (or 'err' if the data is read from the onevm output) can
introduce bugs.

Regards.

Subject: [one-users] '-' or 'err' (instead of 0) as a value for parameters

To: users 


Hi!

ONE shows 0 (zero) as a value for those parameters which it fails to
retrieve. For example,
$ onevm list
  ID USER NAME STAT CPU MEMHOSTNAMETIME
  39 oneadmin   one-39 runn   0  0K01 04:02:29
  40 oneadmin   vps145 runn   0  0K00 08:23:28

I wonder if it wouldn't be more reasonable to show '-' or 'err' instead of
0?
Sorry if that question has been already asked before (I couldn't found
anything similar).

Regards,
Nikolay.

Re: [one-users] poll script return value if VM is not running

[Carlos Martín Sánchez]

Hi Nikolay,

The core looks for those meaningful attributes and updates them only if they
are present and not equal to '-1', but they are not mandatory.
If any of them is not found, the previous value persist.

I would say that your driver should return all values that can be retrieved
from the hypervisor.

The template attributes are sorted in alphabetical order, so you can assume
a fixed order, but you can't be sure about what child elements will be
present since the template may contain anything.

You could however assume the contents if you force the VM creation to be
only done using your OVF to OCA server; or if you limit the VM information
retrieval to work only for VMs created from your code.

Even inside each vector attribute, its sub-attributes are ordered
alphabetically.

Yes, after doing some tests it looks to me that the XML is not modified in
any way by Ruby.

Re: [one-users] VM state is UNKNOWN

[Carlos Martín Sánchez]

Hi María,

This problem is related to the other thread you started [1]. The core marks
the VM state as unknown because the polling script fails to report any
information.

Re: [one-users] Error monitoring VM, Error executing sudo /usr/sbin/xentop -bi2

[Carlos Martín Sánchez]

Hi again,

The script was discarding the first lines, because other versions include
some information about the system before the list of domains.
Please try the patch attached in this new ticket:

Thank you,

Re: [one-users] How to add worker nodes and to configure Open Nebula with XEN?

[Carlos Martín Sánchez]

Hi Anders,

The im_kvm and vmm_kvm MADs are defined in your /etc/one/oned.conf file, you
should uncomment im_xen and vmm_xen.
Follow the xen specific guide [1], but be aware that some steps will be
already done by the express installation. From [2]:

   - Configures sudo for Xen deployments.
   - Configures GRUB for Xen deployments.

Carlos.

Re: [one-users] VM starting fail

[Carlos Martín Sánchez]

Hi Mephysto,

That error is shown when the Core can't find the 'tm_ss' Transfer Manager
Driver.
Please make sure that:

- You defined the host with 'tm_ssh' and 'tm_ss' is just a typo in you
email, as Steffen said. You can check this with onehost show 

- Your /etc/one/one.conf file has the tm_ssh driver uncommented. The drivers
are loaded at start-up, you have to reset OpenNebula if you make any change
to oned.conf. Check the first lines of oned.log, the drivers being loaded
are shown there, and you may find some error messages if something went
wrong.

Regards,
Carlos.

Re: [one-users] Keep all the data from host_pool

[Carlos Martín Sánchez]

Hi,

There is no straight-forward way to do this. We don't have configuration
options for DB manipulation.
I think the best workaround is to create a SQL Trigger [1] [2] , that will
copy the rows to be deleted from 'host_pool' to a new table,
'history_host_pool'.

Please be aware of this bug [3], in some rare cases you may have a new Host
using the ID of an old deleted one.

Carlos.

Re: [one-users] Running FE as Xen dom0/domU?

The FE can be added as a Host just fine.
We would advise to install OpenNebula in dom0, since there's no clear
advantage to an installation inside a VM. It will save you some network
configuration, and you avoid a possible performance downgrade.


You may however have some good reasons to install OpeNebula in a domU.
For instance, your servers may have an old OS and you find it difficult to
install the required dependencies. In that case a virtualized recent
distribution will be easier to set-up. Or if you have big plans for your
domU OpenNebula like migration to new HW, or High Availability setups.

In that case, keep in mind that the VM must be able to see the other Hosts
in your network, attaching its interfaces to a bridge in the private
physical interface. You should also configure an external NFS server.

   Can (or should) long running servers be managed through Nebula ? E.g.
>a blog server. I'd like to have a single view of all the servers

>

Yes, OpenNebula can and should manage all VMs, because it assumes exclusive
usage of the physical resources, and managing VMs manually may lead to IP
collisions.

Moreover, OpenNebula is well suited for long running servers. You can take
advantage of the Fault Tolerance features [1] to resubmit a crashed VM, or
even resubmit the VM in another Host if the first one fails. And, if the
server running OpenNebula fails, it will continue the monitoring and
management of the VMs when it is restarted.


   Can any requirements beyond memory and disc be specified for an

You can define any placement requirement. If you need a specific Host,
REQUIREMENTS = "NAME = myhost"

or you can group some Hosts in clusters [3], and require the VM to be
deployed in any of them:
REQUIREMENTS = "CLUSTER = development"


Best regards,
Carlos.

The Image Repository [1] takes care of the image files. If the storage is
shared (e.g. NFS), and the Images are marked as persistent [2], then the
file in the repository is used rather than cloned.
