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 Sibiao Luo 2012-11-22 08:52:13 UTC 
Description of problem:
migration with usb-storage using remote-viewer to connect, then it can migration successfully, but after a while the destination qemu core dump.

Version-Release number of selected component (if applicable):
host info:
kernel-2.6.32-342.el6.x86_64
qemu-kvm-0.12.1.2-2.334.el6.x86_64
spice-server-0.12.0-2.el6.x86_64
spice-gtk-0.14-5.el6.x86_64
virt-viewer-0.5.2-16.el6.x86_64
guest info:
RHEL6.4-20121106.0-6.4-x86_64
kernel-2.6.32-342.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1.boot a guest with usb-storage using remote-viewer to connect.
eg:...-device usb-ehci,id=ehci -drive file=/dev/vg-90.100-sluo/lv-90-100-usb-storage1,if=none,format=qcow2,cache=none,werror=stop,rerror=stop,aio=native,id=usb-stick -device usb-storage,bus=ehci.0,drive=usb-stick,id=usb-disk,bootindex=3
2.do live migration.
(qemu) __com.redhat_spice_migrate_info 10.66.11.229 5931
(qemu) migrate -d tcp:10.66.11.229:5888

Actual results:
after step 2, the destination qemu core dump after migration complete successfully. i will attach all the qemu output logs later.
- destination qemu

Expected results:
the guest should work well after migration complete, the qemu should no any core dump.
