Hello,
Quickly : a short experience with the restoration of a VM to another server.
I made a backup of all my VM from Proxmox 2.1 on the server 1 to an external USB disk drive. All my VM are KVM one, the format is raw, the disks are IDE and by default it use no cache.
I prepared a server 2 with Proxmox 2.2. This is absolutely not the same material as the server 1 : no RAID, no power supply redundancy ...
I took the backup from y external disk to restore them on the server 2. So far it works.
But, when I started the VMs (all) I got this annoying message : "Boot failed: could not read the boot disk" ...
After some searches and tests, I finally got a workaround from this post : http://forum.proxmox.com/threads/11330-VM-hdd-only-with-cache-write-through-possible
I had to change the default (No cache) disk option to "Write through" option. Maybe it's me that not master this topic or maybe there's something wrong. I don't have the time to search deeper about that, but maybe that could help somebody.
