Hi Anthony,
There seems to be a problem with these. With all 4 patches applied,
I can't boot a domU (4-way, 4G). My dom0 is configured as a 2-way, 16G.
Trying to boot the domU results in the panic below. Also, it would be
nice to include performance data when submitting patches which improve
performance. Thanks,
Alex
