Re: Migrating a VM makes its gluster storage inaccessible

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?
