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.

I retested on 6.2 host, reproduced again when doing ping-pong migration.
Log and CLI attached as well as a snapshot

What is the kernel version ?
Can you also add systems logs (/var/log/messages) especially for the dest host

I want to confirm, the internal error was in the destination machine which was the Sandy bridge ?
I'm asking because I saw that you did live migration ping pong.

Yes, one of the Intel host was Sandy Bridge. This is reproducible on local Sandy Bridge when local migrating. Let me try non Sandy Bridge host and update here.
Comment 15 Orit Wasserman 2012-06-21 04:46:52 UTC 
There is a fix for BZ 756044 https://bugzilla.redhat.com/show_bug.cgi?id=756044
Can you try to see if it helps with the issue ?
Comment 19 RHEL Program Management 2012-07-10 07:16:50 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 20 Orit Wasserman 2012-07-10 11:13:07 UTC 
Hi, any progress with checking the patch ?
Comment 21 RHEL Program Management 2012-07-11 02:06:52 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Comment 22 Chao Yang 2012-07-11 11:57:11 UTC 
It is still reproducible while local migrating on 2.6.32-284.el6.x86_64, qemu-kvm-0.12.1.2-2.295.el6.x86_64 on Sandy Bridge host.

I think this is a duplicate of BZ 852612

can you try to reproduce with qemu-kvm-0.12.1.2-2.325.el6?
