Yes.
If you alloc two vcpus to dom0, you must add dom0_max_vcpus=2 to
command line of xen. If you don't add dom0_max_vcpus, xen alloc one
vcpu to dom0. This is default as you said the above.

e.g. my elilo.conf

image=vmlinuz-2.6.18-xen
        vmm=xen.gz
        label=xen
        initrd=initrd-2.6.18-xen.img
        read-only
        append="com2=115200,8n1 console=com2,vga dom0_mem=1G dom0_max_vcpus=2
sync_console -- rhgb root=LABEL=/ 3 console=tty0 console=ttyS1,115200,8n1"

Okay thanks, so this may seem like a dumb question but, if I have 8
other domUs running all with one vcpu is the xen kernel still going to
use the other cpus? and does `xm top` show the current cpu usage for
the system then (all xen cpus) regardless of how many cpus are on
dom0?

Thanks,
