Re: [one-users] Is there a way to expand output of onevm list?
Hi Steve,
I copied /var/lib/one/tmp/onevm.yaml file into ~/.one/cli/ folder located in user's home dir and set
the value of size parameter of HOST attribute to desired value (in my case it is 15):
{{{
:HOST:
:desc: Host where the VM is running
:size: 15
:left: true
}}}
Hope it helps!
Best regards,
Nikolay.

I am currently running opennebula 4.8.
The default output of onevm list only allows 10 characters
under hostname.
my hostnames are cloudworker which means that all identifying
information is truncated to cloudworke
Is there any way to change the format of onevm list to show the whole node
name, if so, how? I have
a lot of scripts that parse that output.

Re: [one-users] 4.4 Installation instructions are incorrect
Hello Kerry! What makes you think that 4.6 is development version? As far as I know it is a stable one (there is even 4.6.1 with bug fixes). Have a loot at Release cycle [1] Best regards, Nikolay.

Re: [one-users] 4.4 Installation instructions are incorrect
I assume the logic behind is the following: user starts from OpenNebula home page (opennebula.org), then click on Documentation (http://opennebula.org/documentation/) which contains the documentation on the latest stable release. Currently it is written the following: OpenNebula 4.6 Guides (Latest Stable). kerryhall . wrote on 10/06/14 11:23: http://docs.opennebula.org/4.4/ It says 4.4 (Stable) and 4.6 (Devel) On Tue, Jun 10, 2014 at 12:23 AM, kerryhall . kerryh...@gmail.com mailto:kerryh...@gmail.com wrote: On this page here: On Tue, Jun 10, 2014 at 12:19 AM, kna...@gmail.com mailto:kna...@gmail.com wrote: Hello Kerry!

If you are running nfs shared datastore there are several ways you can follow: 1) configure your nfs server to NFSv3 and not NFSv4 since according to [1] and [2] NFSv4 is not supported yet for ploop VMs; 2) switch from ploop-based containers to simfs ones. In that case you have to specify in VM config (or VM template config) VE_LAYOUT=simfs 3) reconfigure datastore to use ssh transfer driver instead of shared one (see info [3]). Regards, Nikolay.

[one-users] two authentication methods in Sunstone
Hello! I wonder if it is possible to enable two authentication methods in Sunstone? As far as I understand from [1] currently only single auth method is supported. I would like to implement the following: first try to use x509 auth method and if it fails then try the next one listed in /etc/one/sunstone-server.conf e.g. like :auth: x509,sunstone i.e. if user doesn't have a proper x509 certs imported in his browser then he still can be authenticated with username/password.

Re: [one-users] Users Digest, Vol 69, Issue 141
Hi Caty, if your datastore is nfs-based then it seems like you faced with issue mentioned in that bug report [1]. Is there any particular reason which makes you not to use latest stable openvz kernel (currently it is 83.2)? Make also sure that the latest stable ploop and vzctl versions are installed. Hope that helps, Nikolay.

[one-users] save changes in persistent VM disk without shutdown
Hello all! I wonder if there is any way to save changes made in persistent VM disk without shutting down that VM? The 'onevm stop' command saves persistent VM disk in /var/lib/one/datastore/0/VMID on the front-end but not in /var/lib/one/datastores/1/ where all registered in datastore VM images are kept. 'onevm saveas' command is not allowed for persistent VM disk. So in order to save changes made in persistent VM disk (what can be treated as making backup) these VM has to be shut down and another VM has to be created e.g. by executing 'onetemplate instantiate' command what resets accounting and history and not preserving assigned resourced.

So we will split this in two, one for the control data and other to be
used/modified by
the user.
For now, as Nikolay suggests this limit somehow part of the
out-of-the-box functionality
(e.g. adding DESCRIPTION in a bulk submission), this functionality
will need a custom
program using OCA. About parsing the out put of onevm show, note that
you can always get
the full pool information with onevm list -x (TEMPLATE included) the
onevm list command
just parse and pick some of this info and present it in a tabular
form...
Thanks a lot for detailed reply and explanations!
JFYI You can easily add new columns to the onevm list command. The following patch adds a new
DESCRIPTION column to the onevm list output:
https://gist.github.com/8f8499704cbee0e5db84
The onevm.yaml can be defined per user in $HOME/.one/onevm.yaml or globally in
/etc/one/cli/onevm.yaml
Hi Daniel,
Thanks for your patch and efforts!
But I wasn't able to archive desired behavior.
I did the following changes:
$ diff /usr/lib/one/ruby/cli/one_helper/onevm_helper.rb{,.orig}
138,141d137
column :DESCRIPTION, DESCRIPTION, :size=12 do |d|
d[TEMPLATE][DESCRIPTION]
end
143c139
:TIME, :DESCRIPTION
---
:TIME
$ cp /etc/one/cli/onevm.yaml ~/.one/
$ diff ~/.one/onevm.yaml /etc/one/cli/onevm.yaml
42,46d41
:DESCRIPTION:
:desc: DESCRIPTION
:size: 20
57d51
- :DESCRIPTION
With help of 'onetemplate update' command I added DESCRIPTION parameter
$ onetemplate show 5|grep -i description
DESCRIPTION=description
and instantiate a VM based on that template.
Although 'onevm show VMID' shows the presence of DESCRIPTION parameter 'onevm list' doesn't show
DESCRIPTION column (neither column name nor content).
'one stop' and 'one start' didn't help.
If you have any guess why it is so then please share it.

Nikolay.

Nikolay.

Hi
Why not using the name of the VM for this?.
The name of the VM I would like to use to put hostname in it and
perhaps use $NAME in
contextualization as e.g.
CONTEXT=[
HOSTNAME=$NAME.domain.org http://NAME.domain.org
http://NAME.domain.org ]
But that would make a sense in case when one could be possible to
specify IP address in
'onetemplate instantiate' command.
Also if you want to append any arbitrary data to the VM (at
creation) you can
simply added
to the VM template as:
DESCRIPTION=this is a web server, use 1234 as root password
This will be stored in the template ans can be queried with the
onevm show command
or in
the Template tab in Sunstone
As far as I understand that will work for a creation of a single VM
but won't if I need to
create a bunch of VMs with help of 'onetemplate instantiate'
command.
Is there any way to modify certain deployed VM's config to add
arbitrary data like e.g.
DESCRIPTION field (something like 'onevm update')?
Moreover, in my opinion it's not convenient to parse the output of
'onevm show'
command when I
need to get a list of all VMs e.g. what have a word web in its
description. It would
be more
convenient to have a separate column for that as I wrote before.
But probably to do
that there
is a need to modify DB schema which is not desirable I guess.

[one-users] hostname and IP address as arguments for 'onetemplate instantiate' command
Dear community, I wonder if there is a way to assign a certain IP address for particular VM created and deployed by 'onetemplate instantiate' command? Right now it looks like IP is chosen randomly from the pool of free IP addresses (leases). Moreover from time to time I need to create a bunch of identical VMs which differ only by hostnames and corresponding IP addresses. It seems that the use of 'onetemplate instantiate' command looks reasonable in that case but I don't know how to pass the IP addresses. I would assume something like $ onetemplate instantiate --name vm%i -m 5 --ip 10.10.10.%i with the following network definition and contextualization section in template description as below: NIC=[ NETWORK_ID=0 ] CONTEXT=[ HOSTNAME=$NAME.domain.org, NAMESERVER=$NETWORK[DNS, NETWORK_ID=0 ] ] I can't use DHCP since venet is used as network devices (I am using OpenVZ hypervisor) and venet doesn't support DHCP. So I wonder what the possible ways to pass hostname and corresponding IP address to the VM deployment file are to be parsed by deploy script and make a proper OpenVZ config file?

Hi Tino, Tino Vazquez wrote on 29/08/11 17:17: Hi Nikolay, Ok, if not on system-wide, please copy them to $ONE_LOCATION/var/remotes, and see how it goes. A hook script copied into $ONE_LOCATION/var/remotes on front-end node appears on CNs in $SCRIPTS_REMOTE_DIR. But it's written the following in [1] and oned.conf (in Hook Manager Configuration): # Virtual Machine Hooks (VM_HOOK) defined by: [...snip...] # command : path can be absolute or relative to $ONE_LOCATION/share/hooks # case of self-contained installation or relative to # /usr/share/one/hooks in case of system-wide installation The above is true only for local hooks (i.e. hooks executed on front-end node). If a hook has to be executed on remote node (remote=yes) then a path has to correspond to the hook script location on CN and thus the citation above is almost never true (it's true only if admin creates exactly the same directory structure for $ONE_LOCATION/share/hooks in case of self-contained installation or /usr/share/one/hooks in case of system-wide installation and puts there the hook script). I think that has to be explicitly mentioned in [1] and oned.conf. By the way, it's not possible to use $SCRIPTS_REMOTE_DIR variable when defining a path for remote hook like VM_HOOK = [ name = vzfirewall, on= RUNNING, command = $SCRIPTS_REMOTE_DIR/hooks/vzfirewall.sh, arguments = , remote= yes ] since an argument for command parameter is translated into $ONE_LOCATION/$SCRIPTS_REMOTE_DIR/hooks/vzfirewall.sh. The value of $SCRIPTS_REMOTE_DIR is unknown for hook manager (?) and/or cluster node(?) (so it's empty). The hook manager is trying to execute $ONE_LOCATION//hooks/vzfirewall.sh and fails. So admin has to specify the value of $SCRIPTS_REMOTE_DIR twice in oned.conf: the first time when defining the variable itself and the second one - for specifying a absolute path of the remote hook on CN. It would be more convenient if admin have a possibility to refer to $SCRIPTS_REMOTE_DIR variable defining remote hooks path.

[one-users] [OpenNebula-2.2.1] add a custom attribute to image
Hi! Is it possible to add a custom attribute to image registered in Image Repository using OpenNebula 2.2.1? For example, the command 'oneimage image_id addattr OSTEMPLATE centos-5' produces the help on oneimage usage and doesn't add specified attribute. So I wonder if it's expected behavior or I am doing something wrong? I am looking for a way to pass a OpenVZ specific parameter to VM deployment file. For the time being I am using the image attribute NAME but as it is explained in [1] such attribute has to be unique among all registered images i.e. it is impossible to register two images in Image Repository with the same NAME.

Yes, this seems like a good approach. Have you tried it out? It look fine to me.
I started to modify $ONE_LOCATION/share/hooks/image.rb file but then
realized that hooks ($ONE_LOCATOIN/share/hooks/image.rb) is executed
locally on FN whereas the VM directory packaging/archiving has to be
done remotely i.e. on CNs. So adding to that hook something that needs
to be done remotely (like
ssh root@CN sudo tar -Sp -C -czf #{source_path} . would break remote
and local hooks logic as I wrote before in [1]
So I see not so much possibilities:
1) add the execution of tar command on remote node in image.rb hook
which is executed on local (front-end) node i.e. such approach breaks
the local/remote hooks logic;
2) create one more custom hook what has to be executed on remote node
and what would archive VM working dir. But there are several issues here:
- how one can make sure that custom hook will be executed before
image.rb one since both of them should be triggered when VM reaches the
DONE state,
- how make that custom hook trigger only upon 'onevm saveas' command
execution or if SAVE sub-attribute of DISK attribute is set to YES.
So I am stuck at that point.
As always any help on that is highly appreciated!

Should it be just STATE='vm status' or script has to return all meaningful for OpenNebula variables (USEDCPU, USEDMEMORY, NETRX and NETTX)? If all variables listed above are mandatory then which values has to be assigned to them (0, -, something else or variables shouldn't have any value assigned) since they can't be retrieved?

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

Hi Nikolay,
Hi Carlos,
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)
Since the problem with restore script and not deploy I guess the changes
need to be done as below:
$ diff one-2.2.0/lib/mads/one_vmm_ssh.rb
one-2.2.0_src/src/vmm_mad/ssh/one_vmm_ssh.rb
104c104
remotes_action(#{@remote_path}/restore #{file} #{deploy_id},
---
remotes_action(#{@remote_path}/restore #{file},

Dear ONE developers,
To perform restore action OpenVZ hypervisor apart from dump file
requires VM ID as well, i.e. the command looks like below:
$ vzctl restore VM_ID --dumpfile path
For more details please see [1].
As far as I understand from
$ONE_LOCATION/var/remotes/vmm/hypervisor/restore files ONE
invokes restore script only with one argument which is the dump file.
I am using XML type of VM_MAD driver in oned.conf (as below) to
perform all actions on OpenVZ VMs:
-8-
VM_MAD = [
name = vmm_ovz,
executable = one_vmm_ssh,
arguments = ovz,
type = xml ]
---8
I wonder what file needs to be change to invoke restore script on
remote node with one more argument ($deploy_id) needed for OpenVZ
hypervisor (it looks for me that such approach should be safe for
other hypervisors since they takes into account only the first
argument).
Thanks!

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).

Hi Tino, There is no way and sense to have more then one disk in VMs (aka containers) based on OpenVZ [1]. You can't assign\attach more disks to OpenVZ VM in principle. The only thing you can do with VM disk resources is to change disk quota for particular VM on the host node. Thus such OpenVZ VM parameters for disk resources management as DISKSPACE and DISKINODES are unique per each VM and in principle can be passed in RAW section although it's not quite proper way to do that.

Re: [one-users] OpenVZ
Hi! Spent some time in attempts to implement OpenVZ support in OpenNebula via libvirt I realized that for the moment probably it was not the most efficient way to do that since libvirt provides pretty poor OpenVZ support. In particular: 1) some of openvz specific parameters/options are missing from libvirt docs (e.g. [1]) despite of they are mentioned in Example guest domain XML configuration at libvirt openvz driver page [2] (I submitted a bug: [3] ); 2) as far as I understand there is no way to specify assigned disk space and disk inodes by libvirt means (feature request: [4]); 3) it looks like network device veth is wrongly assigned inside openvz container (at least I couldn't find the proper way to do that: [5]) and there is no way to use another network device - venet (http://wiki.openvz.org/Venet). 4) total (max) and used (current) memory parameters for certain VM always have a zero value ([6]). Libvirt-users mail-list doesn't help too much to clarify details; Most of issues mentioned above as well as e.g. [7] had been discussed before in libvirt mail-list (some of them more than a year ago) but I couldn't find any submitted bugs and that and those issues still exist. For the moment I have done not so much progress in implementing openvz support in ONE via libvirt: $ git status # On branch one-openvz # Changes to be committed: # (use git reset HEAD file... to unstage) # # new file: src/im_mad/remotes/ovz.d/architecture.sh # new file: src/im_mad/remotes/ovz.d/cpu.sh # new file: src/im_mad/remotes/ovz.d/name.sh # new file: src/im_mad/remotes/ovz.d/ovz.rb # new file: src/vmm/LibVirtDriverOVZ.cc # new file: src/vmm_mad/remotes/ovz/cancel # new file: src/vmm_mad/remotes/ovz/deploy # new file: src/vmm_mad/remotes/ovz/migrate # new file: src/vmm_mad/remotes/ovz/ovzrc # new file: src/vmm_mad/remotes/ovz/restore # new file: src/vmm_mad/remotes/ovz/save # new file: src/vmm_mad/remotes/ovz/shutdown # new file: src/vmm_mad/remotes/poll_vmm.rb # deleted:src/vmm_mad/remotes/poll_xen_kvm.rb # new file: src/vmm_mad/ssh/vmm_ssh_ovz.conf # # Changed but not updated: # (use git add file... to update what will be committed) # # modified: include/LibVirtDriver.h # modified: install.sh # modified: share/etc/oned.conf # modified: src/vmm/LibVirtDriverOVZ.cc # modified: src/vmm/SConstruct # modified: src/vmm/VirtualMachineManager.cc # modified: src/vmm_mad/ssh/vmm_ssh_ovz.conf Taking all mentioned above into account I incline to an opinion it would be better to implement openvz support in OpenNebula by native openvz means like vzctl/vzlist/vzcalc/vzmigrate/vzdump commands just invoking those commands on remote host.

Or you can paste here the output of $ cat /proc/cpuinfo|grep model name vmx|svm flags might be not shown if you machine is booted in XEN enabled kernel. So I would suggest you to check in the web if your CPU model supports VT and if it can be enabled in BOIS.

The im files are copied to the im folder (/tmp/one/im in your case it seems) in the remote host when adding a new host to OpenNebula. They are copied from the $ONE_LOCATION/var/remotes/im on the frontend host, even though there is a copy of them in the $ONE_LOCATION/lib/remotes/im as well, as backup. now it's clear! I put ovz-related files only into /usr/lib/one (ONE is installed in a system wide mode) and they are missing in /var/lib/one/remotes/im/. That's why they weren't copied on remote host during its addition. I've just copied ovz.d into /var/lib/one/remotes/im/. Delete remote host from the pool.

I have used the registered image with VM template but on onevm create

To run VM it needs to be deployed apart from creating VM
$ onevm deploy VM_id Host_id
VM_id is virtual machine id (specified in first column on 'onevm list')
Host_id is registered in ON host id ('onehost list')
E.g.
$ onevm deploy 9 3
