NB BMR and guests on RedHat KVM Hypervisor

Hello, did anybody have experience with Bare Metal Restore and VM guests on RH KVM hypervisor?
We have a RH KVM hypervisor with RHEL6. We successfully BMRestored a VM Linux RHEL5 guest with IDE disks, but we could not with a Vm linux guest with VirtIO disks, because the full backup with BMR option fails to import the config file.

Did anybody have any info/test experience about Netbackup andVirtIO disks with NB BMR option?
Thanks in advanced.

Best Regards,

Andrea

Which volume manager the guest is running with?

Please can you attach bmrsavecfg debug level 6 log generated on your RHEL 5 guest.

We're using LVM as volume manager.
The output of fdisk command is following:

[root@bmrsource netbackup]# fdisk -l

Disk /dev/vda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/vda1   *           1          64      514048+  83  Linux
/dev/vda2              65         325     2096482+  83  Linux
/dev/vda3             326         390      522112+  82  Linux swap / Solaris
/dev/vda4             391        1044     5253255   8e  Linux LVM

Attached the bmrsavecfg debug level 6 log file form guest (I changed file extension from .log to .txt)

Thanks

Hi Andrea,

Thanks for pasting the fdisk output. It clears my doubt.

BMR today does not understand VirtIO disks configuration (/dev/vda and partitions based on it) during client backup. Hence bmr import process will fail.

I would recommend you to check with NetBackup Product Management on this requirement.

Thanks.

Thank you for reply, Mandar.

I supposed was something something related to VirtIO, we did not have any issue using IDE disks.
So, may I open a case with Symantec to deep investigate for that?
It could be useful for everybody to have BMR to understand VirtIO disk configuration also. Isn't it?

Thank you, again.

Andrea, thats very good aim but I afraid if the case would get closed at front-line support being the feature not supported.

If you can make sure it reaches to engineering and gets added into enhancement list then that would work well. Else if you are fine I can register it into list of BMR future items TBD :)

Thanks.

That's ok, Mandar.
