Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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:	Due to a mismatch in interrupt request (IRQ) routing, migration of a Red Hat Enterprise Linux 6.5 guest from a Red Hat Enterprise Linux 6.5 host to a Red Hat Enterprise Linux 7.0 host could produce a call trace. This happened if memory ballooning and a Universal Host Control Interface (UHCI) device were used at the same time on certain machine types. With this patch, the IRQ routing mismatch has been amended and the described migration now proceeds as expected.	Story Points:	---

2.do migration

3.inside guest, do twice reboot

4. on qemu-kvm side, do system_reset

Actual results:
after step2, there is no call trace on serial console and dmesge.
after step3 and step4, guest can reboot successfully and no call trace.

Additional info:
1. I also test "-M rhel6.5.0" for rhel6.5-64 guest, the result is pass as above.
2. I also test "-M rhel6.5.0" for win8-32 guest, after migration, the guest can reboot successfully.

2.do migration

3.inside guest, do twice reboot

4. on qemu-kvm side, do system_reset

Actual results:
after step2, there is no call trace on serial console and dmesge.
after step3 and step4, guest can reboot successfully and no call trace.

Additional info:
1. I also test "-M rhel6.5.0" for rhel6.5-64 guest, the result is pass as above.
2. I also test "-M rhel6.5.0" for win8-64 guest, after migration, the guest can reboot successfully.
