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 4 Min Deng 2022-03-17 07:02:55 UTC 
QE could reproduce the issue on the following build
qemu-kvm-6.0.0-32.module+el8.5.0+12949+ac589a5c.x86_64
qemu-kvm-6.1.0-1.module+el8.6.0+12721+8d053ff2.x86_64
1.On a guest on src host
  See attachment for qemu command line.
2.Start a guest on dst host witn "-incoming defer" 
Expected result,
Migration passed and guest works as expected.
Actual result,
(qemu) qemu-kvm: get_pci_config_device: Bad config data: i=0x34 read: 54 device: 90 cmask: ff wmask: 0 w1cmask:0
qemu-kvm: Failed to load PCIDevice:config
qemu-kvm: Failed to load pcie-root-port:parent_obj.parent_obj.parent_obj
qemu-kvm: error while loading state for instance 0x0 of device '0000:00:04.0/pcie-root-port'
qemu-kvm: load of migration failed: Invalid argument
Comment 6 Min Deng 2022-03-17 07:25:37 UTC 
I'd like to do a summary,
1.The issue can be reproduced on the following builds
qemu-kvm-6.0.0-32.module+el8.5.0+12949+ac589a5c.x86_64/qemu-kvm-6.0.0-33.module+el8.5.0+13041+05be2dc6 (it's the fix version for bug 1999141)
qemu-kvm-6.1.0-1.module+el8.6.0+12721+8d053ff2.x86_64
2.The issue wasn't reproducible on the following builds 
qemu-kvm-6.0.0-33.module+el8.5.0+13041+05be2dc6
qemu-kvm-6.2.0-8.module+el8.6.0+14324+050a5215.x86_64

I will do full regression test for case 2, will update the results later. Thanks !
