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 Jun Li 2014-12-29 10:15:56 UTC 
Description of problem:
boot guest and then do migration. Can not use the PS/2 mouse inside dst guest after migration.

Version-Release number of selected component (if applicable):
qemu-kvm-rhev-2.1.2-17.el7.x86_64
Host kernel:
3.10.0-220.el7.x86_64
guest:
win2012r2-64

How reproducible:
100%

Steps to Reproduce:
1.boot guest cli:
# /usr/libexec/qemu-kvm -name test -machine pc,dump-guest-core=off -cpu Broadwell,+movbe,+bmi1,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff,hv_time,check,enforce -enable-kvm -sandbox on -m 2G -vnc :1 -realtime mlock=off -smp 4,sockets=1,cores=2,threads=2 -uuid b123c5df-d85b-2ce9-5e93-926f4f4ce03b -nodefconfig -nodefaults -rtc base=utc -drive file=/home/win2012r2-64.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=none,snapshot=on -device virtio-blk-pci,bus=pci.0,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,id=hostnet0,vhost=on,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:13:20:fe:11:11,bus=pci.0 -drive file=/home/en_windows_server_2012_r2_x64_dvd_2707946.iso,if=none,id=iso1,media=cdrom -device ide-cd,drive=iso1,id=sys-iso1 -drive file=/usr/share/virtio-win/virtio-win-1.7.2.iso,if=none,id=virtio-win-driver,media=cdrom -device ide-cd,drive=virtio-win-driver,id=sys-virtio-win-driver -monitor stdio -vga cirrus
2.boot dst guest cli(on the same host).
# /usr/libexec/qemu-kvm -name test -machine pc,dump-guest-core=off -cpu Broadwell,+movbe,+bmi1,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff,hv_time,check,enforce -enable-kvm -sandbox on -m 2G -vnc :2 -realtime mlock=off -smp 4,sockets=1,cores=2,threads=2 -uuid b123c5df-d85b-2ce9-5e93-926f4f4ce03b -nodefconfig -nodefaults -rtc base=utc -drive file=/home/win2012r2-64.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=none,snapshot=on -device virtio-blk-pci,bus=pci.0,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,id=hostnet0,vhost=on,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:13:20:fe:11:11,bus=pci.0 -drive file=/home/en_windows_server_2012_r2_x64_dvd_2707946.iso,if=none,id=iso1,media=cdrom -device ide-cd,drive=iso1,id=sys-iso1 -drive file=/usr/share/virtio-win/virtio-win-1.7.2.iso,if=none,id=virtio-win-driver,media=cdrom -device ide-cd,drive=virtio-win-driver,id=sys-virtio-win-driver -monitor stdio -vga cirrus -incoming tcp::5800
tap1
3.do migration from src to dst.
(qemu) migrate -d tcp:127.0.0.1:5800
4.check the guest mouse can be used or not inside dst guest.

Actual results:
After step4, can not use the mouse inside dst guest.

(qemu) info mice 
* Mouse #2: QEMU PS/2 Mouse

Expected results:
Can use the mouse as normal inside dst guest.

Doesn't reproduce.  Please retest with qemu 2.3
Comment 3 Jun Li 2015-05-05 06:34:53 UTC 
Retest with qemu-kvm-rhev-2.3.0-1.el7.x86_64.

rebase fixed this appearently.  setting to modified then.
Comment 5 Shaolong Hu 2015-06-18 09:00:40 UTC 
Verified on qemu-kvm-rhev-2.3.0-2.el7.x86_64:

1. boot guest on src host:
/usr/libexec/qemu-kvm -name test -machine pc,dump-guest-core=off -cpu Broadwell,+movbe,+bmi1,hv_relaxed,hv_vapic,hv_spinlocks=0x1fff,hv_time,check -enable-kvm -sandbox on -m 2G -vnc :1 -realtime mlock=off -smp 4,sockets=1,cores=2,threads=2 -uuid b123c5df-d85b-2ce9-5e93-926f4f4ce03b -nodefconfig -nodefaults -rtc base=utc -drive file=/mnt/windows_img/win2012-64r2-virtio.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,cache=none,snapshot=on -device virtio-blk-pci,bus=pci.0,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,id=hostnet0,vhost=on,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,id=net0,mac=00:13:20:fe:11:11,bus=pci.0 -drive file=/home/en_windows_server_2012_r2_x64_dvd_2707946.iso,if=none,id=iso1,media=cdrom -device ide-cd,drive=iso1,id=sys-iso1 -drive file=/usr/share/virtio-win/virtio-win-1.7.2.iso,if=none,id=virtio-win-driver,media=cdrom -device ide-cd,drive=virtio-win-driver,id=sys-virtio-win-driver -monitor stdio -vga cirrus

2. boot guest on same host, with same cmd plus "-incoming tcp:0:5555"

3. do migration:
(qemu) migrate -d tcp:127.0.0.1:5555

4. after migration, guest mice works correctly.
