Anyone familiar with XenServer, knows one of its weaknesses is the processing power of dom0. This is something XenServer admins have been complaining about for awhile. Although Citrix has made efforts in the past to address this issue, I think their latest effort in XenServer 6.1.0 is the best to date. Now, with a simple command line, you can adjust the vCPU assigned to dom0. (Up to 8 processors) I've noticed in large XenServer based CloudStack implementations, the hypervisor began to struggle under heavy provisioning loads. Although I have not had the chance to test CloudStack w/ XenServer 6.1.0, I suspect this new feature was introduced to address such issues. Check out the link below for more information about this feature.
