Thanks,
After running for awhile vcpus=1 hangs as well. There
are no errors in any of the logs.
I've tried using xen in the interim and it all works: 1 cpu, 1+cpu,
and hvm. I guess I'll just stick with that until kvm is working
on intel i7. My machine is a Gateway FX6801-01 in case that
helps.
thanks
Chandra
