We are able to pre-create the storage given that a full copy is
requested (copy-storage-all, not copy-storage-inc) and the images reside
in a location covered by a libvirt 'directory' storage pool at least on
the destination of the migration.
Really interesting. I see an option "--migrate-disks" and I guess this
will do this. Something like:
virsh migrate --live --p2p --copy-storage-all --persistent \
--undefinesource --verbose ----migrate-disks vda \
$vm qemu+ssh://$other/system
Is there a way to simply migrate all writeable disks without specifying
them?
Unfortunately we can't do it for incremental at this point.
So far I understand it, incremental means something like a
synchronisation like rsync does. So parts what are allready there, don't
have to be copied again. Please correct me when I am wrong.
When the disks are not there at the other side, an incremental backup
would be the same as a full copy.

I'm not sure now whether the new size will be picked up, but nothing
should break, so you can give it a try. Certainly a shutdown and start
of the VM will fix it if it's not picked up or a blockresize.
Again thanks for your help!
