Public bug reported:

Binary package hint: kvm

I got a new intel i7 (950) and installed Ubuntu 9.04 and kvm-84
on it.  I use this same config for a bunch of other machines
and it works fine.  All my other machines are core2/xeon boxes
though.  All are 64bit.

I try to run guestVM from an image that works on another box.
If I set vcpus in the config to 1 the guest starts.  Otherwise
it hangs during boot after the lines:

<hang's hard here -- I can only leave the console and do a virsh destroy to kill>

If I set vcpus=1 then guest starts fine.
If I start another guest, the first one hangs hard.
During either of these cases there is no information/error in syslog.
I do see "kvm: 10933: cpu0 unhandled wrmsr: 0xc0010117 data 0" during
boot but other users/bug reports say that thisis fixed or doesn't
cause a problem.
