Situation as follows: mixed cluster with 3.5 and 3.6 nodes. Now in

migrate VM's while they're running on different versions.
Live migration should always work within a single cluster. What do Vdsm
logs say on both the source and target hosts when the migration fails?
The most interesting part is happening when I power down a VM, and
then run
it on a 3.6 node. Only on CentOS 7 VM's, I'm getting a "no bootable
device"
error. I have a mixed setup of ubuntu, CentOS 6 and CentOS 7. Ubuntu &
CentOS 6 are fine.
Tried shooting grub in MBR again, to no effect. I start the VM then on a
3.5 node and all is fine.
So the VM is indicated as starting in Engine and BIOS or GRUB can't find
the device to boot from? Could you provide Vdsm logs from both
successful and unsuccessful boot of the same VM?
