[libvirt-users] DriveReady error after live migration

[Steve Gaarder]

I have three machines running libvirt under Scientific Linux (RHEL 
derivative) version 6.  The virtual machine disk images are running SL 5 
and 6, are all stored on NFS, and I can do live migrations with

virsh migrate --live guestname qemu+ssh://vmhostname.math.cornell.edu/system

Trouble is, within a day or two after the migration, the guest hangs up 
with repeated DriveReady errors and has to be shut down forcibly and 
rebooted.

I am using Sanlock, with the lock files also stored on NFS.

Any ideas?
