Hi All,
I am trying to provide services to guest VMs where I wish to run guest VMs in a loop.
I wish to use a core to schedule a guest VM, service it eg. execute an ISR etc and then return to the context of Xen on that core, so that I can then schedule the next VM on that core.
In doing all this, the goal is to avoid the calls to VMEntry and VMExit. Is there a workaround for this to be done or will I always have to face a VMExit to return to the Xen context on that core ?
Looking forward to some pointers.
Thanks,
Devdutt.
