Lowering cluster CPU level : safe?
by Nicolas Ecarnot 04 Aug '14

04 Aug '14

Hi, I'm trying to add some Westmere hosts into a Sandybridge cluster, and of course, they get refused : "Host xxxxxxxxx moved to Non-Operational state as host does not meet the cluster's minimum CPU level. Missing CPU features : model_SandyBridge" I tried to lower the cluster level but I get this warning : "Change Cluster CPU level There are running VMs. Lowering the Cluster CPU level might prevent migration of these VMs to some of the Hosts in the Cluster. Are you sure you want to continue?" As a frightened chicken, I clicked "Cancel" and turned to you : how safe is it to lower the CPU level? I understand some instructions will be missing, and maybe performance will change, but we don't have heavy CPU usage yet, so this may not be a big issue. I was wondering what will happen to my existing VMs? Will I have to modify some setup? What may prevent migration between westmere and sandybridge hosts? Regards, -- Nicolas Ecarnot

status disks locked
by Andy Michielsen 23 Jul '14

Hello, I have a vm in my ovirt setup which has it's disks locked after I wanted to take a snapshot. I have a separate node and an engine and already rebooted them both but it still keeps on telling me it's disks are locked. Where does this info come from and what can I do to rectify the situation. Kind regards.

Can HA Agent control NFS Mount?
by Andrew Lau 22 Jul '14

22 Jul '14

Hi, I was just wondering, within the whole complexity of hosted-engine. Would it be possible for the hosted-engine ha-agent control the mount point? I'm basing this off a few people I've been talking to who have their NFS server running on the same host that the hosted-engine servers are running. Most normally also running that on top of gluster. The main motive for this, is currently if the nfs server is running on the localhost and the server goes for a clean shutdown it will hang because the nfs mount is hard mounted and as the nfs server has gone away, we're stuck at an infinite hold waiting for it to cleanly unmount (which it never will) If it's possible for instead one of the ha components to unmount this nfs mount when it shuts down, this could potentially prevent this. There are other alternatives and I know this is not the "supported" scenario, but just hoping to bounce a few ideas. Thanks, Andrew

Online backup options
by Steve Dainard 21 Jul '14

21 Jul '14

Hello Ovirt team, Reading this bulletin: https://access.redhat.com/site/solutions/117763 there is a reference to 'private Red Hat Bug # 523354' covering online backups of VM's. Can someone comment on this feature, and rough timeline? Is this a native backup solution that will be included with Ovirt/RHEV? Is this Ovirt feature where the work is being done? http://www.ovirt.org/Features/Backup-Restore_API_Integration It seems like this may be a different feature specifically for 3rd party backup options. Thanks, Steve

[QE] Hardening Guide
by Sandro Bonazzola 17 Jul '14

17 Jul '14

Hi, while I was working on Bug 1097022 - ovirt-engine-setup: weak default passwords for PostgreSQL database users I was wondering where to write hardening tips described in comment #18. It looks like we don't have any page on oVirt wiki about hardening. Anyone interested in contributing to such page? I guess it can be created as http://www.ovirt.org/OVirt_Hardening_Guide Thoughts? -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration.

VM HostedEngie is down. Exist message: internal error Failed to acquire lock error -243
by Andrew Lau 14 Jul '14

Hi, I'm seeing this weird message in my engine log 2014-06-06 03:06:09,380 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (DefaultQuartzScheduler_Worker-79) RefreshVmList vm id 85d4cfb9-f063-4c7c-a9f8-2b74f5f7afa5 status = WaitForLaunch on vds ov-hv2-2a-08-23 ignoring it in the refresh until migration is done 2014-06-06 03:06:12,494 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.DestroyVDSCommand] (DefaultQuartzScheduler_Worker-89) START, DestroyVDSCommand(HostName = ov-hv2-2a-08-23, HostId = c04c62be-5d34-4e73-bd26-26f805b2dc60, vmId=85d4cfb9-f063-4c7c-a9f8-2b74f5f7afa5, force=false, secondsToWait=0, gracefully=false), log id: 62a9d4c1 2014-06-06 03:06:12,561 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.DestroyVDSCommand] (DefaultQuartzScheduler_Worker-89) FINISH, DestroyVDSCommand, log id: 62a9d4c1 2014-06-06 03:06:12,652 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-89) Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: VM HostedEngine is down. Exit message: internal error Failed to acquire lock: error -243. It also appears to occur on the other hosts in the cluster, except the host which is running the hosted-engine. So right now 3 servers, it shows up twice in the engine UI. The engine VM continues to run peacefully, without any issues on the host which doesn't have that error. Any ideas?

Can we request images for the ovirt image repository?
by Andrew Lau 14 Jul '14

14 Jul '14

Hi, Is there a form where we can request images in the public ovirt image repo? Either way, it'd be nice if we could get the project atomic images added http://rpm-ostree.cloud.fedoraproject.org/project-atomic/images/f20/qemu/ Cheers.
