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 xiagao 2017-05-10 06:47:34 UTC 
Description of problem:
guest hang after do migration with scsi controller under q35


Version-Release number of selected component (if applicable):
qemu-kvm-rhev-2.9.0-3.el7.x86_64
kernel-3.10.0-663.el7.x86_64
OVMF-20170228-4.gitc325e41585e3.el7.noarch

How reproducible:
3/3

Steps to Reproduce:
1. boot guest with qemu cmd line [1]
2. start dst guest with “-incoming tcp:0:5800 ”
3. doing live migration to dst host
{"execute": "migrate","arguments":{"uri": "tcp:0:5800"}}
4. after migration,check guest

Hit the same issue on q35+seabios.
Comment 3 Dr. David Alan Gilbert 2017-05-10 18:38:29 UTC 
1) Can you try with a different NIC than e1000e - I'm tracking a separate e1000e migration bug
2) Does a Linux guest fail in the same way?

Try with "virtio-net-pci", can not reproduce.

> 2) Does a Linux guest fail in the same way?
Not fail in the same way.

Hmm in that case I wonder if it's related to bz 1447935 that's a windows migrate problem with e1000e.

Comment 6 Dr. David Alan Gilbert 2017-05-11 11:51:44 UTC 
when you say 'guest hang' is it completely hung? Does the mouse still move?
On bz 1447935 the mouse still moves, just nothing else happens - or if it does happen it happens very slowly.


(My suspicion is the network card is giving out lots and lots of false interrupts so the guest gets nothing else done)

Hi, in my test environment the guest is completely hung and the mouse can not move.
