Any idea on which hypervisors (preferably free and opensource ones) support it? Thanks.

I actually don know. My goal is to do what I explained in my question and I am looking for a solution that does that. Since it is an academic research, I want to be able to that in code.

2013-11-12 19:21:13 -0600 asked a question How to change vCPU and pCPU mapping at runtime?

Is it possible to change the mapping of vCPUs to pCPUs in OpenStack at runtime. For example, suppose I have a CPU socket with 4 cores (A, B, C, D) and four vCPUs (V1, V2, V3, V4). Also suppose in the beginning the mapping is as follows:

V1 -> A

V2 -> B

V3 -> C

V4 -> D

Would it be possible to change this mapping at runtime to something like this?

V1 -> B

V2 -> A

V3 -> C

V4 -> D

My goal is to do what I explained in my question and I am looking for a solution that does that. Since it is an academic research, I want to be able to that in code. Any idea on which hypervisors (preferably free and opensource ones) would help me solve this problem?
