Comment 2 Vivian Bian 2011-03-18 05:15:27 UTC 
# virsh save local /opt/test.save
Domain local saved to /opt/test.save

# virsh restore /opt/test.save
Domain restored from /opt/test.save

# virsh save local local.save
error: Failed to save domain local to local.save
error: operation failed: Migration unexpectedly failed

# pwd 
/root

Tried some times , found if we save the guest to /root , then will always
failed . Save to other directories , will succeed .

Comment 4 Osier Yang 2011-03-18 07:25:46 UTC 
I considered to duplicate this to https://bugzilla.redhat.com/show_bug.cgi?id=619846, but as this BZ is to 6.0.Z, so perhaps we need to keep it, and
backport the fix when 619846 is fixed.
Comment 5 RHEL Program Management 2011-04-04 01:59:23 UTC 
Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

I agree that this BZ is a dup of 619846, and I'm closing as such.

*** This bug has been marked as a duplicate of bug 619846 ***
