Hmm, if you use the gEDF scheduling algorithm, this may not be
possible. Let me explain why.
In the MPR2 model, it computes the interface with the minimum
number
of cores. To get 2 VCPUs for a VM, the total utilization (i.e.,
budget
/ period) of these two VCPUs must be larger than 1.0. Since you ask
for 2 domains, the total utilization of these 4 VCPUs will be
larger
than 2.0, which are definitely not schedulable on two cores.
Well, if we are speaking about test-cases similar to described in

Missing the link?
Yep, I've missed the link.
