I ran the kvm command with the -cpu qemu32 added and there was no
difference.

I removed qemu and ran kvm - no difference.

Here is the out of the 2 date commands, the run of kvm without qemu
installed,  and cat /proc/cpuinfo.  There was about a 5 second delay for
me get back to the screen and run the 2nd date command.

The long startup time is still there.  I shutdown the xp vm and
restarted - I had about an 8 second delay before I reran the 2nd date
command.
