DriveReady error after live migration
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?
