------=_Part_19443521_333909629.1436796129418 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Dear Listmembers, I have a 3 node ovirt system, it's based on self-host glusterfs. Today, I did a vm migration but it was unsuccessful. The vm got a paused state and it was unable to resume and it was impossible to switch off. Cause I killed it on the compute node, but it's remains as paused state. How can I switch to power-off state this machine? At this moment I can't power on this vm.....:( In this case are there any "friendly" solution for the future? If I do a restart for vdsmd, that will cause other "bad" things? Thanks in advance.

This VM is not managed by the engine
by Mark Steele 13 Jul '15

13 Jul '15

I have a VM that was not started and is now showing as running. When I attempt to suspend or stop it in the ovirt-shell, I get the message: status: 400 reason: bad request detail: Cannot hibernate VM. This VM is not managed by the engine. Not sure how the VM was initially created on the ovirt manager. This VM is not needed - how can I 'shutdown' and remove this VM?

Host failed to attach one of the Storage Domains attached to it

This is a multi-part message in MIME format. --------------050503030109030902030106 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hello, We have a small oVirt deplopyment, with 2 INTEL CPUs and 1 AMD, therefor we defined 2 clusters. One of the Intel machines is running the management as well (We called this SOL). This deployment is connected to a NAS through NFS shares. Suddenly (no more than 2 days) SOL is reported as "Non operational" and in the Action Items is saying " Host failed to attach one of the Storage Domains attached to it." All other machines seems to be fine.

Live VM Backups
by Chris Jones - BookIt.com Systems Administrator 10 Jul '15

10 Jul '15

From what I can tell, you can only backup a VM to an export domain if the VM is shut down. Is a live VM backup not possible through oVirt? If not, why not? Most other virtualization tools can handle this. If it is possible, how do I do it through the backup API? api.vms.myvm.export requires it to be shutdown so what would the alternative be? Thanks. -- This email was Virus checked by UTM 9. For issues please contact the Windows Systems Admin.
