Just a follow-up on this issue, we're getting the best uptime ever with 
the VM using scsi/virtio, so the problem seems fixed.

I have also checked and it looks like we created the VM with default 
scsi config, so I'm almost sure we tried changing network interfaces but 
not disk drives.

Thanks a lot for your help.
