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.

Fixed In Version: qemu-kvm-1.5.3-60.el7_0.1
Doc Type: Bug Fix
Doc Text:
Prior to this update, a bug in the migration code caused the following error on specific machine types: after a Red Hat Enterprise Linux 6.5 guest was migrated from a Red Hat Enterprise Linux 6.5 host to a Red Hat Enterprise Linux 7.0 host and then restarted, the boot failed and the guest automatically restarted. Thus, the guest entered an endless loop. With this update, the migration code has been fixed and the Red Hat Enterprise Linux 6.5 guests migrated in the aforementioned scenario now boot properly.

Steps of Reproduce:
1.boot a rhel6.5 guest and win8-64 guest on src host(rhel6.5)

3.migration
(qemu) migrate -d tcp:10.66.11.149:5555

4. reboot guest inside guest
#reboot

Actual results:
for rhel6.5 guest, reboot fail.  this is guest console log.
