This means that neither in-guest suspend/resume nor qemu-kvm migrate-to-file (which fails for a different reason I'm trying to debug now) works.

It does not work with any version of windows I tried, too (which is winXP, win7 32 and win7 64bits). Windows enters an endless loop with a black screen during suspend (eating 100% CPU time). What's wrong/broken in linux? Can it be fixed?
