[Qemu-devel] [Bug 1635339] Re: qxl_pre_save assertion failure on vm "save"

[Gerd Hoffmann]

Will be fixed in the windows driver, yes.

But throwing core dumps isn't exactly nice, even in case the guest is
buggy, thats why the qemu workaround, so we simply refuse to live-
migrate instead of crashing.
