One final thing which come to mind given your request which you might or might not be aware of:Â Xen has "arinc653", a maintained realtime scheduler which will likely be more appropriate to your requirements than the default "credit" scheduler.

For simplicity's sake at the moment I propose to runÂmy VM as the onlyÂVM on a vcpu.ÂMy assumption is that this way there will be no scheduling.ÂIs this assumption correct?

Your best option would be to create a cpupool for the individual cpu you want your VM to be running on. This way you can schedule that cpu using arinc653 independently of dom0 and domU being scheduled using regular credit.
