RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.

Comment 9 releng-rhel@redhat.com 2010-11-10 21:24:50 UTC
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.
