Since I usually run qemu-kvm from command line instead of using VMM,
might I suggest you try that and see if you are using the virtualization
hardware rather than emulation? Because it sounds a lot like my install
of x86_64 on an i686 host, totally emulated. And it wasn't hung, just
I'm not suggesting that you drop VMM for normal operations, just that
you try without it to be sure you are getting what you need.
