[Users] Problem on boot after deleting last snaphot
by Gianluca Cecchi 16 Apr '13

Hello, snapshot testing in 3.2.1 on f18 host with http://gerrit.ovirt.org/#/c/13172/ (enable template from snapshot) - create one vm named prova_snap from centos 6 template and choose preallocated storage - power on - create test_snap1 with vm powered on Snapshot test_snap1 creation for VM prova_snap has been completed. I have now: Current OK Active VM 2013-Apr-16, 14:09 OK test_snap1 - create some files - shutdown VM VM shutdown initiated by admin@internal on VM prova_snap (Host: f18ovn03). VM prova_snap is down. Exit message: User shut down - snapshots --> select "test_snap1" --> preview Snapshot-Preview for VM prova_snap was initiated by admin@internal. Snapshot-Preview for VM prova_snap has been completed. And I have under "Description" field of snapshots view test_snap1 (Preview Mode) (in coloured bold) 2013-Apr-16, 14:09 In Preview test_snap1 (Preview Mode) - Power on VM --> ok the files created after the snapshot are not there. - Shutdown VM and undo the operation to come back (forward actually) to the active state Restoring VM prova_snap from snapshot started by user admin@internal. VM prova_snap restoring from Snapshot has been completed. - Power On VM Ok, all files are there again. - create test_snap2 with vm powered on Snapshot test_snap2 creation for VM prova_snap was initiated by admin@internal. Snapshot test_snap2 creation for VM prova_snap has been completed. Now I have Current OK Active VM 2013-Apr-16, 16:21 OK test_snap2 2013-Apr-16, 14:09 OK test_snap1 - create some files /testfile_aftersnap2 - shutdown VM - snapshots --> select again the first snapshot named "test_snap1" --> preview Snapshot-Preview for VM prova_snap was initiated by admin@internal. Snapshot-Preview for VM prova_snap has been completed. Now I have: 2013-Apr-16, 16:25 OK Active VM before the preview 2013-Apr-16, 16:21 OK test_snap2 2013-Apr-16, 14:09 In Preview test_snap1 (Preview Mode) - Power on VM --> ok the files created after the snapshots are not there. - Shutdown VM and commit so that subsequent snapshots (in my case test_snap2) should be erased Restoring VM prova_snap from snapshot started by user admin@internal. VM prova_snap restoring from Snapshot has been completed. Now I correctly have only this: Current OK Active VM 2013-Apr-16, 14:09 OK test_snap1 - Power on VM And now I should be in situation as right after test_snap1 creation if I power on te VM --> OK Now I would like to delete the remaining snapshot (test_snap1) and begin a new story...

What should I need to configure to put HA working? I mean, when a host broke all the VM automatically move to another host. Do I need to have Power management enabled? Thanks

[Users] How to import KVM machines into oVirt iSCSI
by Nicolas Ecarnot 12 Apr '13

12 Apr '13

Hi, Reading the docs all day long helped me to setup a nice Data center in iSCSI mode, connected to a big LUN in a san. Many many points are working, mostly thanks to you, people of this list. Apart from this oVirt setup (1 manager, 3 nodes, 1 san), I have a completely separated ubuntu hypervisor running a standalone local KVM with a local storage. I have not a clear view of how I will manage to import these VM into oVirt. Of course, I've read about ovirt-v2v (and its huge amount of dependencies...), but I'm not sure this is the way I have to follow? As far as I've understood, v2v seems to be dedicated to connection between oVirt datacenters, or vmware or Xen plateforms, but I see nothing about the connection to a distant standalone KVM hypervisor. One more thing that is unclear to me, and seems related, is the notion of export / import domain. I read that this principle could allow me to export (then to backup) my VMs. This could help me to import some VMs. But I read that this export domain has to be the same type of my datacenter (iscsi), so this is not helping me with my standalone kvm hypervisor. I'd be glad to get some light on these points. -- Nicolas Ecarnot

[Users] Ipa server inside ovirt itself. ..
by Gianluca Cecchi 12 Apr '13

12 Apr '13

Hello, I have a test environment where I am short of hw. My engine is based on fedora 18 and I would like to test freeipa on centos 6. What are the drawbacks of creating a vm that is also one authentication domain for ovirt itself (apart the obvious ones)? Can i set it so that is the first to start? Can i set a subset of VMs to start only if this one is up and is giving ipa service (for example through a test connect command? ) Thanks Gianluca

Gianluca, Thanks for your so detailed report. But unfortunately I can't find any clue related to this network interface status problem. Sorry for that. Maybe other guy can add more comments. At this moment, I suspect the link of em1.311 and probably its underlying interface em1 went down occasionally and came up in a short time. Is it possible? You could check the system log '/var/log/messages' to find related messages. > Thanks for your input Mark. > At the moment all is well again with the host; anyway I'm going to > give a long explanation of what I did below and so possible reasons > for that situation. > There is also feed for developers answers in that ... > > I cannot connect at the moment to the host to cut and paste in text > but I have access to java console and here is a screenshot containing > the line you requested (captured now that all is ok and host up and > runnign with two VMs): > > https://docs.google.com/file/d/0BwoPbcrMv8mvdmdIMUxTRVRVUzg/edit?usp=sharing > > Which fields are expected to be indicators of problems, as I had yesterday?

Hello, is there any bugzilla tracked for this? At my part I openend https://bugzilla.redhat.com/show_bug.cgi?id=947255 because with some servers I have also the problem that I'm put into a dracut shell with kernel higher than stock f18 initial one. Are there other ones? Anyone already tried latest kernels such as 3.8.5-201.fc18.x86_64? What is the kernel shipped with ovirt-node iso? Can we use it eventually on a standard fedora 18 system? BTW: with my home pc where I have model name : AMD Athlon(tm) II X4 630 Processor and an all-in-one 3.2.1 installation over fedora 18, I have no problems with 3.8.5-201.fc18.x86_64 kernel. Thanks, Gianluca

[Users] ovirt and web portals favicon
by Gianluca Cecchi 11 Apr '13

11 Apr '13

Hello, not a big deal, but could ovirt have its own logo and so map it to the favicon on portals? At the moment I see the well known Red Hat logo.... fedora has its own even if sponsored by Red Hat as I imagine oVirt is... Just for knowledge, not debate... PS: at the moment it seems the ovirt.org has no favicon, so it could be the occasion to make both... Thanks, Gianluca

[Users] VM crashes and doesn't recover
by Limor Gavish 10 Apr '13

10 Apr '13

Hello, I am using Ovirt 3.2 on Fedora 18: [wil@bufferoverflow ~]$ rpm -q vdsm vdsm-4.10.3-7.fc18.x86_64 (the engine is built from sources). I seem to have hit this bug: https://bugzilla.redhat.com/show_bug.cgi?id=922515 in the following configuration: Single host (no migrations) Created a VM, installed an OS inside (Fedora18) stopped the VM. created template from it. Created an additional VM from the template using thin provision. Started the second VM. in addition to the errors in the logs the storage domains (both data and ISO) crashed, i.e went to "unknown" and "inactive" states respectively. (see the attached engine.log) I attached the VDSM and engine logs. is there a way to work around this problem? It happens repeatedly. Yuval Meir
