I have installed Xen 3.10 on ubuntu 7.04 through repositories following instructions given at    
and have installed Dapper guest domains. I have a quad-core processor and the host domain uses all the four processors and has 4 vcpus. But for each guest domain, I am able to use only 1 vcpu and hence can increase it's cap value to 100% only. Including lines like vcpu = 4 in the config file does not help as I am unable to log into the guest domain after that neither using xm console, nor using ssh. Also, xm vcpu-set does not work.
Has this anything to do with the old version of ubuntu?? How can I achieve more than 1 vcpu for guest domains?
