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 ZhangQian 2010-08-17 05:12:03 UTC 
Description of problem:
After migration, the mouse in rhel3.9 guest does not work.

Version-Release number of selected component (if applicable):
# uname -r
2.6.32-63.el6.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.109.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Start rhel3.9 guest on src host
# /usr/libexec/qemu-kvm -m 2G -smp 2 -cpu qemu64,+x2apic -balloon none -no-kvm-pit-reinjection -rtc base=localtime,clock=host,driftfix=slew -usbdevice tablet -drive file=rhel3.9.raw,if=none,format=raw,cache=none,werror=stop,rerror=stop,id=drive-virtio0 -device virtio-blk-pci,drive=drive-virtio0,id=virtio-blk-pci0,addr=0x8 -netdev tap,id=hostnet0,vhost=on,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,mac=20:20:78:90:12:93 -boot c -monitor stdio -vnc :8 -qmp tcp:0:4445,server,nowait

2.Start listening mode on dst host

3.Do migration
src host:
(qemu)migrate -d tcp:10.66.65.134:5888
(qemu) info migrate
Migration status: active
transferred ram: 2016856 kbytes
remaining ram: 180816 kbytes
total ram: 2113920 kbytes
(qemu) info migrate
Migration status: completed
(qemu) info status
VM status: paused

dst host:
(qemu) info status
VM status: running 

Actual results:
After migration complete, the mouse do not work, keyboard can work normally.


Expected results:
The guest can be operated by mouse and keyboard smoothly. 


Additional info:

(1)rhel3.9 guest info
# uname -r
2.4.21-63.EL

(2)I also tried the rhel5.4-32 guest, no such issue found.
Comment 2 RHEL Program Management 2010-08-17 05:38:49 UTC 
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
Comment 4 Amit Shah 2010-10-13 12:20:15 UTC 
Can this still be reproduced?
Comment 7 Gerd Hoffmann 2010-11-25 12:23:07 UTC 
Can't reproduce locally.

What does 'info mice' print before and after migration?
What does 'info usb' print before and after migration?

Does it happens with other RHEL/Win guests?
