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.

Comment 10 Sibiao Luo 2015-02-26 09:51:17 UTC 
Tried to reproduce this issue on both 'Intel + rhel guest' and 'AMD + win7 guest', but did not reproduce it. I checked my steps with flang who reproduce/verify the bug #1074219 and also checked with coli for it.

host info:
3.10.0-229.el7.x86_64
qemu-kvm-1.5.3-60.el7.x86_64
guest info:
'Intel + rhel guest'
'AMD + win7 guest'

Steps:
Use the auto test script to install a RHEL7/Win7 guest with xhci device and keep ping-pong migration during installation.

Results:
Migration & installation successfully with xhci device.

############################

So here i just try 5 times with the latest qemu-kvm version with the same testing to verify this issue on both 'Intel + rhel guest' and 'AMD + win7 guest'.

host info:
3.10.0-229.el7.x86_64
qemu-kvm-1.5.3-60.el7_0.12.x86_64
guest info:
'Intel + rhel guest'
'AMD + win7 guest'

Steps:
Use the auto test script to install a RHEL7/Win7 guest with xhci device and keep ping-pong migration during installation.

Results:
Migration & installation successfully with xhci device.

## Also tried to query the patch changelog from the qemu-kvm package which i have saw the kvm-xhci-add-sanity-checks-to-xhci_lookup_uport.patch in the fixed qemu-kvm-1.5.3-60.el7_0.12.x86_64 package.

# rpm -q qemu-kvm
qemu-kvm-1.5.3-60.el7.x86_64
# rpm -q --changelog qemu-kvm-1.5.3-60.el7.x86_64 | grep 1180410

# rpm -q qemu-kvm
qemu-kvm-1.5.3-60.el7_0.12.x86_64
# rpm -q --changelog qemu-kvm-1.5.3-60.el7_0.12.x86_64 | grep 1180410
- kvm-xhci-add-sanity-checks-to-xhci_lookup_uport.patch [bz#1180410]
- Resolves: bz#1180410

Base on above, we can set verified this issue to verify status i think. Please correct me if any mistake, thanks.

Best Regards,
sluo
