Hi Arsene,

i have to apologize, your hint to the QXL driver was right.
after searching in the wrong places for most of the time i finally 
looked into the logs of the hypervisor host and found

libvirtError: internal error: unable to execute QEMU command 'migrate': 
qxl: guest bug: command not in ram bar

which led me to https://bugzilla.redhat.com/show_bug.cgi?id=1446147

you can't use 
https://www.spice-space.org/download/windows/qxl-wddm-dod/qxl-wddm-dod-0.18/ 
in windows 2012, but when uninstalling the Red Hat QXL driver completely 
the VM is finally able to migrate

thanks
matthias
