Hello, =20 at the moment we are investigating stalls of Windows XP VMs during live migration.

In parallel the SPICE console allows to move open windows. But as soon as one clicks on the start the menu the system gives no response. =20 Even after updating to qemu 2.0 with virt-preview respositories the behaviour stays the same. Looks like the system cannot access
This really seems more either SPICE or QEMU related=85. You can isolate the behavior to that single VM? Or single OS type(others = work ok)? or it's happening for any other VM randomly? Thanks, michal
