I using it with Xen and vserver. With Xen and large disk images it
works. Live migration and failover works. Healing is a major problem. It
blocks the image for sometime so you have downtime anyway. I have to
write a heartbeat ressource to manage the healing before restart the
VM. Linux Vserver works to but there are performance issues im working
on. It is no problem to "dd" a file to gluster with reasonable speed but
in "realtime" vserver is much faster on drbd then on gluster. Maybe I hit
a "lot of small files" Problem here or there is a problem with vservers
COW mechanism. I use 1.3.12 only.
