Re: [one-users] VMWare Server 2.0 and non-persistent images to minimize copy when deploying

[Manish Sapariya]

As a alternative I also tried hacking the code
to get the same effect as you have suggested.

1. I changed my nfs clone.sh to do nothing, but
to create empty directory.
2. I changed the remotes/vmware/deploy to modify
   the deployment.0 to refer to my non-persistent
   disk instead of one which ON creates.
3. With above changes when I deploy, ON creates the
   VM and starts it as well.
- The first VM runs fine.
- The second VM however fails, because ESX says
  the image is already in use. This happes because
  libvirt fails to mark the disk that it creates
  as non-persistent.
- If I change that attribute of the failed VM, ESX
  is able to run the VM.

So I think I will run into this same issue with the approach
you suggested as well. I believe this is the inherent lack
of support for non-persistent image by libvirtd. I checked
the libvirt documenation and they have one feature bug open
to support non-persistent disks.

Could you please confirm if my understanding is correct
or am I missing certain subtle point?

Thanks and Regards,
Manish

Hi Manish,

You can avoid the copy of the image if you:

  1) Use the dummy TM drivers
  1) Stop using the image catalog, and input the SOURCE of the disks
with the following format

[DATASTORE] relative/path/to/disk

The path is relative wrt the DATASTORE.

hope it helps,

Hi,
We have are using OpenNebula 1.4 using following kind of setup.
The non-persistent disk that I used in OpenNebula 1.4 is not

The reason it worked with 1.4 is that it copied the directory as
it is without looking into the directory. My .vmx file was modified
to had a link to non-persistent disk and hence the solution was working.

2.0 specifically copies the vmdk file and then creates a deployment
file. And hence my 1.4 solution is not working with 2.0.

My question is, can I tell opennebula to use specific image on
hypervisor, instead of making a copy of vmdk and using that as the
instance disk.

I was able to specify a quad-CPU VM using virt-manager,
and that's also used after deployment via ONE.

The original question remains, is it possible 
to specify the number of processors afterwards 
in the VM template ?

First of all, thank you for your possitive comments. We are keen to get
feedback from the community about the brand new SunStone component.

It is a very good idea to improve the dashboard and the detailed info
panels in the ways you describe. In order to keep track of your
proposals I have opened two feature request tickets:

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

[Shi Jin]

Thanks. I just replied your redmine case.
So is it true to say that since 2.0, if a VNET is created by oneadmin
(uid=0) and not published (the default), it cannot be used by other users?
I actually find it is still usable by other users if there is only one VNET
in the VM.

FYI, my uid=0 is called cloudadmin instead of oneadmin but I don't think it
should create any problem, right?

Thank you very much.

 Hi there,

 From the documentation, it says

 I have created two vNETs, intranet-office and LAN-1, both created by the
 oneadmin user (uid=0) and as the document says, any other user can use 
 these
 vnets, at least in my experience, one VNET per VM.

 But I found that if another user wants to deploy a VM with two NICs,
 both owned by uid=0, then we will get a permission error:
 > Sat Feb 26 16:51:44 2011 [ReM][E]: [VirtualMachineAllocate] User [6]
 not authorized to perform CREATE on VM Pool
 If I publish any one of the VNET, the dual NIC setup would work again.

 I think this is probably a bug, right?

Hi,

The upcoming 2.2 release will be focused on fault tolerance, it will
provide the features covered in [1].

The oned redundacy is being studied on some specific deployments, that
expertise is available through C12G Labs [2].

Re: [one-users] OpenNebula 2.0 with default vmware drivers

[Tino Vazquez]

Hi Manish,

OpenNebula doesn't ship with the old VMware drivers anymore. The
combination would work (although this is not tested), but it is not
recommended since the new drivers feature a much better integration
with ONE and VMware.

I've answered to the other thread with a possible solution, hope it helps.

Regards,

-Tino

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] VMWare Server 2.0 and non-persistent images to minimize copy when deploying

[Tino Vazquez]

Hi Manish,

You can avoid the copy of the image if you:

 1) Use the dummy TM drivers
 1) Stop using the image catalog, and input the SOURCE of the disks
with the following format

   [DATASTORE] relative/path/to/disk

The path is relative wrt the DATASTORE.

hope it helps,

-Tino

[one-users] tm_context bug

[Olivier Sallou]

Hi,
there is an issue with tm_context.sh when using contextualisation.
As shown below tmp dir used is:

TMP_DIR="$ONE_LOCATION/var/$DST_HASH"

However, in open nebula system-wide install, this is set to /var/ 
and opennebula user does not have rights to create dirs in /var (or user 
should be root).


This should be set to a /var/opennebula/ where one user would have 
access to /var/opennebula



Regards

Olivier

[one-users] VM with multiple CPUs in template ?

[Steffen Neumann]

Hi,

Our applications benefit from SMP with multiple CPUs.

Question: How do I specify a dual/quad CPU in template.one ?

The documentation http://www.opennebula.org/documentation:rel2.0:template
mentions fractions (e.g. 0.5) but a value of CPU=2.0 does not 
create a 2CPU system. I also tried two CPU=1.0 entries, also no luck.

(We're running one-2.0 with KVM) 

Yours,
Steffen

[one-users] SunStone - First Look

[Toens Bueker]

Hi *,

just to spark the discussion about SunStone I'd like to deliver my
first impressions 

- fast and snappy experience
- clear navigation
- nice popups for error messages and infos
- comprehensive dialogues for the creation of VMs, networks, etc. I
  really like that you can paste the one-template in the "advanced"
  section.

What I'd like to see:
- A sensible use of the dashboard. The information, which is displayed
  there right now, could be presented in a more compact form, instead of
  the five boxes. Which would leave some space for more interesting data
  like some Ganglia graphs, critical logs, monitoring events, etc.
  
- The same goes for the "detailed information pane" in the lower half
  of the display, which could contain "richer" information. E. g.
  it would be nice to have more detailed graphs concerning the
  respective host, the leases in a virtual network linked to their
  respective VMs (a click would bring me to the respective VM-page),
  etc.
  
So far for now.

Kind regards,
Töns

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

The Request Manager component logs are written in oned.log file. We could

Re: [one-users] PUT GET base64 encoded string contextualization mechanism

[Daniel Molina Aranda]

Hi,

The method that OpenNebula provides to give configuration parameters
to a new virtual machine is using an ISO image (OVF recommendation).
The OCCI and EC2 servers also use this kind of contextualization.
Therefore, if you want to get this information you will have to use
the context scripts that are explained here [1]

* In the EC2 case, you can define a value:
$ ./econe-run-instance -d Myvalue ami-0023
And this value will be base64 encoded and accesible inside the context
script of the virtual machine, in a variable called EC2_USER_DATA.

* In the OCCI case, you can define the following template:
$ cat ./template.occi

  vmtest
  small
  
192.168.0.5
192.168.4.9
  


$ ./occi-compute create template.occi
or
$ curl -u oneuser:sha1_pass http://localhost:4567/compute -d
"vmtest...small"
In this case you will find two variables inside the context.sh script
called IP and DNS.

OpenNebula does not implement the EC2 user data system, where you can
get your variables from a server using GET HTTP from curl. As
explained before all the contextualization in OpenNebula is made using
an ISO image.

Hope this helps.

Re: [one-users] EC2 interface and user data question

[Daniel Molina Aranda]

Hi Oliver,

Yes, the user data is added to the context tag. This information will be
placed in a variable called EC2_USER_DATA, that you can get using the
CONTEXT system of OpenNebula.

Regards.
