Description of problem:
This is more a "heads up" for now.
rhel-6.0 has a __redhat.com_spice_migrate_info monitor command to pass the informations needed for spice client migration. The patch has been submitted upstream, but isn't merged (yet). If the patch is accepted upstream in time for 6.1 the monitor command will loose the "__redhat.com" prefix in 6.1.
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.
Moving to MODIFIED, as we have had patch for this a long time:
tested with libvirt-0.9.4-11.el6.x86_64
1. start a guest with spice graphical framebuffer
2. connect to guest spice client session
3. migrate guest
Actual result :
guest could be migrated seamlessly , so set bug status to VERIFIED
Technical note added. If any revisions are required, please edit the "Technical Notes" field
accordingly. All revisions will be proofread by the Engineering Content Services team.
Cause: QEMU changed monitor command that tells SPICE some migration infos (e.g. where are we gonna migrate, what port)
Consequence: Libvirt would be unable to send these information to SPICE, so session could break which will break down seamless migration
Fix: Libvirt adapted to new monitor command
Result: Users can perform seamless migration
