Live Migration Problem with Solaris Guest

[M@ario]

Hello!

I got the most strage error message today, when I tried to live migrate a KVM Solaris guest with ZFS disks.

ERROR: online migrate failure - VM 57355 qmp command 'migrate' failed - Block format 'vpc' used by device 'drive-ide0' does not support feature 'live migration'

Now I'm confused because all my disks are container LVs on a shared FC storage. Does proxmox/qemu actually look inside of the LVs when live migrating?

Do not use vpc (convert it).

Do not use vpc (convert it).

Actually I wasn't aware that I did. But probably this is because the VM was migrated from some Xen server. I hope qemu-img convert can fix this.

Hi,
How did you migrate from Xen Server? Last time I tried I couldn't use qemu-img conversion because Xen also use qemu.
I ended it up using clonezilla and worked perfectly.

Hth,

Hth,

I copied (dd) the Xen LV over ssh to an empty Proxmox LV. Thats why I originally expected to have a raw volume on Proxmox.
I converted the proxmox LV with qemu-img today and live migration now works as expected.
