Can we run MPI programs using HPC rolls on nodes configured as VM Containers, just as we do if the appliace type was Compute. Is there any other configuration required. I dont have any virtual compute nodes inside the VM Containers.
in theory this is possible, just like using the cloud in practice you still need to partition the cpu and setup the queue with the vcpu of your VM these vcpu will not be used by the node or other VM IMHO, unless you need some security reason to hard partition your node/cluster a private cluster/cloud will have better utilization without VM -LT

Theoretically yes, but you have to do some work... You have to configure SGE to submit host to that machine (Rocks doesn't include it automatically as it does for compute).
Moreover Dom0 (at least on 5.4.3) are set up so that only 1 vcpu and 700MB of RAM are allocated to them, so you also have to change that.
I wouldn't go down for that path if I were in you.
