[PVE-User] backup restore - drive not bootable anymore

Please try cache=writeback in  your VM configuration file. It looks like a problem with "cache=none" (the default setting) I have. "writeback"  is just a workaround. Example:

cat /etc/qemu-server/100.conf
virtio0: data1:vm-100-disk-1,cache=writeback

Hope it's helpful,

Betreff: [PVE-User] backup restore - drive not bootable anymore

Hello to all

I have one cluster (1.9) with two proxmox nodes.
There is one ubuntu 10.04 server VM that I succesfully made backup of.

But when I do (successfull) restore on the second node, under different VMID, this hdd does not appear to be bootable. (error no bootable device

The intesion was to check backup-restore procedure.

I kindly ask for help
and every tip would be very appreciate

Thank you very much in advance
