[Xen-users] Co-scheduling HVM domains...

["Roger Cruz" <rcruz@xxxxxxxxxxxxxxxxxxxxxxxx>]

I have a multi-processor, multi-core environment where I will be running an application on one HVM domain A (Windows 2003) and another app in another HVM domain A’ (Windows as well).  There will be multiple instances of this pair combination.  For performance reasons, I would like to find out if there is any way to control the scheduling of the paired domains, such that

 

1)       if domain A is scheduled on a physical CPU 1, domain A’ is also scheduled at the same time on cpu 2. or

2)       if domain A is scheduled on physical CPU, domain A’ is the next domain to be scheduled on the CPU, even if domain B was the next legal owner of the time slice.

 

Assigning a higher priority to a domain type (A or A’) may not work because multiple domains of one type may be available simultaneously.  I need to guarantee that once a domain is scheduled, its corresponding pair will run simultaneously (in another CPU) or  immediately after.

 

I’m new to Xen so forgive me if this is trivial question to which I have not found the answer yet.
