Hi,

I freshly installed kernel 2.6.32-rc2 using userspace qemu-kvm 0.12.4.

When I live migrate a 32-bit opensuse-11.2 VM, the incoming VM shows
the following error after the mem transfer has finished:

kvm: unhandled exit 80000022
kvm: kvm_run returned -22

cmdline:
/usr/bin/qemu-kvm-0.12.4 -net none -drive format=host_device,file=/dev/mapper/iqn.2001-05.com.equallogic:0-8a0906-e1861b105-4cb000e7e8c4bf3b-opensuse-11-2-i586,if=ide,boot=on,cache=none,aio=native -m 1024 -monitor tcp:0:4003,server,nowait -vnc :3 -name 'opensuse-11.2-i586' -boot order=dc,menu=on -k de -incoming tcp:172.21.55.20:5003 -pidfile /var/run/qemu/vm-154.pid -mem-path /hugepages -mem-prealloc -rtc base=utc -usb -usbdevice tablet -cpu qemu64,model_id='Intel(R) Xeon(R) CPU E5430 @ 2.66GHz'

Migrating the same VM worked with 2.6.34 kvm module.

Thanks,
Peter
