[Gluster-users] Migrating a VM makes its gluster storage inaccessible

[Paul Boven]

Hi everyone,

On the libvirt Wiki, I found the text below which might well apply to 
our live-migration issue:

"The directory used for storing disk images has to be mounted from 
shared storage on both hosts. Otherwise, the domain may lose access to 
its disk images during migration because source libvirtd may change the 
owner, permissions, and SELinux labels on the disk images once it 
successfully migrates the domain to its destination. Libvirt avoids 
doing such things if it detects that the disk images are mounted from a 
shared storage. "

So perhaps libvirtd fails to recognize that it is on shared storage, and 
it is the originating libvirt that throws a wrench in the wheels by 
changing the ownership?
