It doesn't matter - any VM can run on any CPU core and none require a dedicated CPU core. If your application is such that you are concerned about latency, the chances are that no virtualization solution is going to be good enough. Otherwise don't worry about it.

[keyboard, network] I am planning vnc to view the ubuntu's running in VM's So I have to pin 1st core for dom0 and on second core my actual VM's would run ? Would you think it would be a feasible solution in terms of latency ?

From a conceptual level if I have to run 2 os (VM) on xen, then in effect there would 3 VMs running 2 guest os's for my purpose and the dom0. How would 3 VM's run on two cores ? Is it possible to affine cores in xen ?If it is anything like x86, then you can overbook cores - Xen will manage what gets to run fairly. You can also specify how many cores you want dom0 to use and pin them, as well as specifying how many and which cores domU should run on.
