Problem description:

After installing a HVM guest, edit your guest config file and increase the
number of vcpus to > 1. Then, boot up your guest and check "xm list" to see the
number of vcpus and then check "xm top" and look at the number of vcpus. You
will notice that "xm list" is reporting only one.

In xend.log everything looks good as far as the parameters that get passed in.
the problem is that the gusts are not picking up more than 1 vcpu.

Detail:

- hvm-config file has "vcpus=4" set. 

when booting guest os, here are the actual status:
