OK,
I see.. the problem is, that I'm trying to hunt down bug causing hangs
when 2.6.32 guests try to run tcpdump - this seems to be reproducible even on latest 2.6.32.x, and seems like it depends on kvm-clock..
So I was thinking about bisecting between 2.6.32 and latest git which doesn't seem to suffer this problem but hitting another (different) problem in 2.6.32 complicates thinks a bit :(
If somebody would have some hint on how to proceed, I'd be more then grateful..
cheers
