Hi,
I've done a git bisec between v1.2.16 and v1.2.17 to try to debug this
problem myself, and I found that the "problem" comes from the following
commit:
93a19e283e5a147d147d84383aaaa8be63b6a68d qemu: migration: selective
block device migration
So it seems that I miss something :-).
This commit implements a --migrate-disks option on virsh migrate
command which allow to select which disks are to be migrated. By
default, disks are not migrated, this is why I got this error.
Good news, this new feature also solves my problem to migrate VMs with
local + rbd disks.
