Yes.

I am using xen that comes default with redhat/centos 5.4 which is 3.0.3. So this is not possible with this version?

Thanks
Paras.

Assuming you have newish version of Xen (3.3 is new enough), you can try

vcpus=8
vcpu_avail=1

That would start domU with 1 vcpu, but allow it to be increased later
up to 8 vcpus.
