[Users] Starting VM gets paused
by Nicolas Ecarnot 16 Jun '13

16 Jun '13

Hi, After two months of stable usage of this 3.1 oVirt setup, here comes the first blocking issue for which I've no other mean to ask some hint. When I'm starting a VM, the start process is running fine. Being fast enough, we can ssh-connect to it, but 5 seconds later, the VM is paused. In the manager, I see that : 2013-03-22 09:42:57,435 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.VdsBrokerObjectsBuilder] (QuartzScheduler_Worker-40) Error in parsing vm pause status. Setting value to NONE 2013-03-22 09:42:57,436 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (QuartzScheduler_Worker-40) VM serv-chk-adm3 3e17586d-bf8f-465b-8075-defaac90bc95 moved from PoweringUp --> Paused And on the host, I see one warning message, no error msg, and many looping repeated messages : * Warning : Thread-1968::WARNING::2013-03-22 09:19:18,536::libvirtvm::1547::vm.Vm::(_readPauseCode) vmId=`3e17586d-bf8f-465b-8075-defaac90bc95`::_readPauseCode unsupported by libvirt vm * Repeated msgs, amongst other repeated ones : Thread-1973::DEBUG::2013-03-22 09:19:20,247::libvirtvm::220::vm.Vm::(_getNetworkStats) vmId=`3e17586d-bf8f-465b-8075-defaac90bc95`::Network stats not available Thread-1973::DEBUG::2013-03-22 09:19:20,247::libvirtvm::240::vm.Vm::(_getDiskStats) vmId=`3e17586d-bf8f-465b-8075-defaac90bc95`::Disk hdc stats not available I made my homework and found some bugs that could be similar : https://bugzilla.redhat.com/show_bug.cgi?id=660598 https://bugzilla.redhat.com/show_bug.cgi?id=672208 and moreover : https://bugzilla.redhat.com/show_bug.cgi?id=695393 - I tried to restart the node's vds daemon : same behavior - I tried to reboot the node : same behavior - I tried to to restart the manager's engine : same behavior - I tried to run this VM on another node : same behavior - I tried to run another VM on the node I saw the issue : the other VM is running fine. I don't know if I have to conclude that this issue is specific to this VM, but I sounds like yes. Things to say about this VM : - it it a RH6 IIRC. It has already been successfully started, migrated, stopped and rebooted many times in the past. - it has 3 disks : one for the system and two for datas. - it has no snapshots - it has no different or complicated network setup My storage domain is a SAN, iSCSI linked, and doing good job since months. I must admit I'm a bit stuck. Last thing I haven't tried is to reboot the manager, though I'm not sure that would help. -- Nicolas Ecarnot

[Users] mozilla-xpi for Ubuntu
by Mario Giammarco 03 Jun '13

Hello, I need a working mozilla-xpi for Ubuntu 12.04 (and soon 12.10). It is strange that an opensource project as ovirt is only working on Fedora. Thanks in advance for any help. Mario

[Users] Migrating engine-setup to otopi
by Alex Lourie 10 May '13

10 May '13

Hi All Recent development of the otopi [1] framework allows us to migrate the engine-setup, upgrade and cleanup (and potentially other) utilities to implementation as an otopi plugin. Potential benefits of such a move are: 1. Be able to port engine to other distributions. 2. Be able to install engine in a development mode. 3. Be able to customize installation easily. 4. Share installation of components (reports, dwh). 5. Modular implementation, reduce maintenance costs. 6. Code reuse of installer code for multiple purposes (host-deploy, enigne-setup). Currently we are in the process of creating a 'setup' plugin for the otopi, and the progress can be monitored at [2]. The current roadmap for the feature is as follows: 1. Recreate the configuration utilities as plugins in otopi. 2. Support side-by side installation using both the old and the new utilities. 3. Switch to the new utility when the confidence that it is on-par with an old one is high. Our goal is to have the new utilities ready for 3.3 release (at least for the step 2 in the roadmap). We'd like to hear as much feedback as possible, so we could address it as soon as possible. Thanks!

[Users] forced shutdown with client agent
by Thomas Scofield 01 May '13

01 May '13

I have run into a scenario after installing the client agent. If a VM is shutdown, the client agent calls the shutdown command with a 1 minute timeout. Dummy-2::INFO::2013-03-28 14:05:21,892::vdsAgentLogic::138::root::Shutting down (timeout = 30, message = 'System Administrator has initiated shutdown of this Virtual Machine. Virtual Machine is shutting down.' Since the shutdown command is called with time parameter the VM sets the /etc/nologin file. When the VM is forced down the /etc/nologin file is not cleared and when it comes back up only root can login until the /etc/nologin file is cleared. Is their some some reason the shutdown time is set to 30 seconds (rounded up to 1 minute in the code)? Are there any know issues with setting this to 0? Is this the right way to change it to 0? psql engine postgres -c "update vdc_options set option_value = '0' where option_name = 'VmGracefulShutdownTimeout';"

Usually, if everything is running as it should, the problem is that the Linux machine is not configure to work with the same authentication server as the one that the RHEV-M is using. Gal.

[Users] oVirt support for backup/restore
by Ricky Schneberger 28 Apr '13

28 Apr '13

Hi, How can I do if I want to schedule a daily live-snapshot of a VM for backup purpose? I have backup software inside my VMs (Netvault), but in some cases I just want to do daily snapshots and use them as backups. -- Ricky Schneberger

[Users] oVirt 3.2.1 and clone from snapshot.... argh...!!!
by Gianluca Cecchi 28 Apr '13

28 Apr '13

Hello, in my opinion 3.2.1 for fedora 18 doesn't contain this: http://gerrit.ovirt.org/#/c/11254/ that was one of the biggest problems of 3.2 see also this thread of mine: http://lists.ovirt.org/pipermail/users/2013-February/012653.html I had to recompile 3.2 in the mean time and after update to 3.2.1 I have again the same problems: - clone from snapshot blocked white window - snapshot details pane no information for network and disks So this update was totally worthless for me and I have to recompile again 3.2.1.... bad!

[Users] Configure spice plugin for wan
by Gianluca Cecchi 22 Apr '13

22 Apr '13

I remember someone talking about an option of setting spice to operate over wan, in the sense that this way automatically it would disable effects in windows 7 VM, ecc... I don't remember if this is a VM parameter, hook or other... Or if this is an option available only in RHEV-M Any pointer? Thanks, Gianluca

[Users] Templates and originating VM relationship
by Gianluca Cecchi 22 Apr '13

22 Apr '13

Hello, oVirt 3.2.1 on Fedora 18. I customize a CentOS 6.4 VM and when I comfortable I select "make template". I don't take any snapshot for the VM before this. I thought that VM would have been disappeared, transforming itself into a template, instead at the end I have both the template and the originating VM. Apparently with the same name for the disk and the same storage domain.... What is exactly the relationship between them? Can I safely remove the originating VM? I already tested making template and then deleting it and then being able to power on again VM and make a new template from the originating VM. The rhevm 3.1 admin manual is not so clear about this: it contains a note regarding " Take a snapshot of the virtual machine at this stage if you wish to use the virtual machine (as a virtual machine) after using it to create a template. " But if behavior of oVirt 3.2.1 has to be the same with it, this doesn't explain itself based on my experience.... Thanks in advance for any information Gianluca
