[Qemu-devel] Migration of WinXP Guest -> usb+network failure

[Peter Lieven]

Hi,

is there any known issue when migrating a WinXP SP3 guest with qemu-kvm 0.13.0 
or qemu-kvm-0.12.5?

If I migrate such a guest with a Realtek rtl8139 Network Device and an USB 
Mouse Tablet 
after migration the USB Tablet doesn't work any more and network stalls. I have 
seen the mouse
moving a few seconds after migration and that stop moving.

If I go to hardware manager and disable + reenable USB Controller and Network 
Controller
it works perfectly again.

Command Line:
/usr/bin/qemu-kvm-0.13.0  -net tap,vlan=141,script=no,downscript=no,ifname=tap0 
-net nic,vlan=141,model=rtl8139,macaddr=52:54:00:ff:00:93   -drive 
format=host_device,file=XXX,if=ide,boot=on,cache=none,aio=native  -m 1024 
-monitor tcp:0:4001,server,nowait -vnc :1 -name 'winxp-test'  -boot 
order=c,menu=on  -k de  -incoming tcp:172.21.55.35:5001  -pidfile 
/var/run/qemu/vm-265.pid  -mem-path /hugepages -mem-prealloc  -rtc
