[Gluster-users] gluster and kvm livemigration

[BGM]

Hi Paul,
thnx, nice report,
u file(d) the bug?
can u do a
watch tree - pfungiA <path to ur vm images pool>
on both hosts
some vm running, some stopped.
start a machine
trigger the migration
at some point, the ownership of the vmimage.file flips from
libvirtd (running machnie) to root (normal permission, but only when stopped).
If the ownership/permission flips that way, 
libvirtd on the reciving side
can't write that file ... 
does group/acl permission flip likewise?
Regards
Bernhard
