I think the important detail is that HVMOP_flush_tlbs doesn't take a target
domain - it always flushes the _caller's_ TLBs. I guess you want to
flush the TLBs of another domain for some reason? AFAICS the version in
mainline Xen has never taken an argument so perhaps you could add one
(making sure to keep backward compatibility, of course).

Thanks, Tim.

Yes, I am trying flush a guests TLBs from dom0. I am using mem_events, and are seeing events that are not caught all the time. The difference appears to be that the guest does a mov cr3 in the case where they are caught.

I was hoping it was a simple matter of flushing the guest TLBs somehow.
