How reproducible:
100%


Steps to Reproduce:
1、source :/home/autotest/client/tests/kvm/qemu -name vm1 -monitor stdio  -serial unix:/tmp/serial-20101018-180959-y4MT,server,nowait -drive file=/home/autotest/client/tests/kvm/images/RHEL-Server-6.0-64-virtio.qcow2,index=0,if=virtio,media=disk,cache=none,boot=on,format=qcow2 -net nic,vlan=0,model=virtio,macaddr=02:6F:EB:00:60:e3 -net tap,vlan=0,ifname=virtio_0_8000,script=/home/autotest/client/tests/kvm/scripts/qemu-ifup-switch,downscript=no -m 2048 -smp 2 -cpu qemu64,+x2apic -soundhw ac97  -spice port=8000,disable-ticketing -qxl 1 -rtc-td-hack -M rhel5.5.0 -usbdevice tablet -no-kvm-pit-reinjection

2、dest :/home/autotest/client/tests/kvm/qemu -name vm1 -monitor stdio  -serial unix:/tmp/serial-20101018-180959-y4MT,server,nowait -drive file=/home/autotest/client/tests/kvm/images/RHEL-Server-6.0-64-virtio.qcow2,index=0,if=virtio,media=disk,cache=none,boot=on,format=qcow2 -net nic,vlan=0,model=virtio,macaddr=02:6F:EB:00:60:e3 -net tap,vlan=0,ifname=virtio_0_8001,script=/home/autotest/client/tests/kvm/scripts/qemu-ifup-switch,downscript=no -m 2048 -smp 2 -cpu qemu64,+x2apic -soundhw ac97  -spice port=8001,disable-ticketing -qxl 2 -rtc-td-hack -M rhel5.5.0 -usbdevice tablet -no-kvm-pit-reinjection -incoming tcp:0:5200

3、execute the following command in the source:
   (qemu) migrate -d tcp:localhost:5200
   
Actual results:
the dest guest will reboot after execute the command " migrate -d tcp:localhost:5200 " and the source guest won't stop.

Expected results:
the source guest stop and the dest guest will continue to  run 


Additional info:

if executing the command "migrate -d tcp:0:5200" instead of  the command "migrate -d tcp:localhost:5200" ,the migration will finish normally.

there is no problem with vnc

Comment 2 Gerd Hoffmann 2010-10-18 13:38:25 UTC

The configuration must be identical on both ends.  You have '-qxl 1' on the source and '-qxl 2' on the destination though.  Please fix and test again.

 there is no problem after '-qxl 2' changed to '-qxl 1' .
thanks!
