Description Amit Shah 2010-05-06 16:19:10 UTC
Description of problem:

The current patches for spice-vmc don't save/restore guest or libspice data across migration, which will lead to data loss and unexpected conditions.

Comment 3 Alon Levy 2010-05-16 08:52:34 UTC
The patch currently in the queue isn't the latest, but generally the patch that should be here removes the ring so the bug is fixed in the empty sense.

That said, testing should include migrating a machine and verifying all the functionality that vdagent supplies works after. That functionality is a mouse channel and automatic resize of screen when spiceclient connects with right flag.

Comment 8 lihuang 2010-08-03 15:32:59 UTC
currently we can not verify this bug on the latest qemu-kvm version (-106.el6) due to bug#618168.
I have test migration(both live and offline) on -78.el6 with spicevmc device. PASS
setting to verified. please create new bug if problem is detected in later version.

Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
