[Xen-devel] Avoiding VmEntry/VmExit.

["Devdutt Patnaik" <xendevid@xxxxxxxxx>]

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.
