Description Gerd Hoffmann 2011-01-06 09:48:03 UTC

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.

Comment 2 RHEL Program Management 2011-04-04 01:48:52 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.

Comment 3 Michal Privoznik 2011-09-09 15:15:04 UTC

Moving to MODIFIED, as we have had patch for this a long time:

libvirt-qemu-Fix-seamless-SPICE-migration-with-older-qemu.patch

Comment 6 Vivian Bian 2011-09-13 09:34:49 UTC

tested with libvirt-0.9.4-11.el6.x86_64

Steps :
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

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
