Snapshots auto generated for live Storage
by André Freitas 23 Jul '14

23 Jul '14

Hi, after i had successfully migrated the disks to a different nfs datastore, i now have a vm with 3 snapshots: 1 current with the description "Active VM" and 2 more with the description "Auto-generated for Live Storage". For what i have been reading online, i can only delete snapshots with the vm offline. is this true? Second, should i commit the live storage snapshots before i delete them or its safe to delete them without commit?

Backup solutions for Ovirt
by saurabh 22 Jul '14

22 Jul '14

Hi All, I am using Ovirt for my QA environment almost 15 virtual servers, and it is working as expected. The only thing I am worried about is the backup solutions in case of failure or system crash. I tried looking into the LVM structure that is created by Ovirt but it seems a bit complex. Please let me know the proper solution (if there is any) for backing up my environment in case of failure.

Misaligned Disk after resize
by Neil 22 Jul '14

22 Jul '14

Hi guys, We re-sized (expanded) a Server 2003 VM a few weeks back and since then the CPU load seems to be rather excessive. Also in the oVirt GUI it reports the disk is misaligned, I've done a bit of reading and it sounds like the only way to correct the alignment again is to re-install, is this the only option? Thank you. Regards. Neil Wilson.

Server Engine and Host Server at the same Hardware
by William Juliano Gutierres 22 Jul '14

22 Jul '14

Hi, I'm testing the oVirt and reanding the documentation I discovered that oVirt needs two separeted servers: the Engine and at least one host server. So, I have two main questions: - No 1: I have just one good hardware enough to run this solution. So, before I go out running for an another new hardware, I would like to know if is that possible run the oVirt Engine and the oVirt Host Server in the same hardware (install the engine, and when add a host, point to the same Engine address). Is it possible? - No 2: I read about the self-hosted engine, but it was not clear how do I start it (assuming that I have one hardware, wich one I install first?). And if it is possible in that way, I would like to know about you if you have a normal performance doing this way. Thank you!

Guest VM CPU Information Different from the Host
by Punit Dambiwal 22 Jul '14

22 Jul '14

Hi, In my Ovirt cluster i am using the following CPU (Intel(R) Xeon(R) CPU E5-2648L v2 @ 1.90GHz),but in the guest machine it shows "Intel Xeon E312xx (Sandy Bridge)" Seems it recognize E5 CPU as E3 CPU....is there any way to modify it to "Intel Xeon E526xx (Sandy Bridge)" instead of "Intel Xeon E312xx (Sandy Bridge)" Thanks, Punit
