It would be useful if all shutdown/reboot operations were

I'd prefer an extra sched_op (maybe SCHEDOP_remote_shutdown with
accompanying sched_remote_shutdown structure). This will need to be
invokable by the emulator mini domain at some point in the future, so
adding this as a dom0_op isn't really for the best.

Ok, that's workable. Is there anything else that needs modification ?
Do you foresee a need for any sort of need for filtering and/or
permissioning of allowable domains as specified in remote_shutdown ?
As long as a non-privileged domain may execute this op, what
level of protection(s) need to exist? (That also was part of my
factoring it into a DOM0 op).
I'm willing to go with anything that gets the job done. This is
one of several points of asymmetry that I'd like to see get
resolved.
Thanks,
