we plan to have 2 of them which seem to make most sense
"warm" without applying config changes and keeping qemu process (i.e. als=
o keeps Run Once,Stateless, pooled VM config/state)
"cold" which kills qemu and is completely driven by Engine,
and applies c=
onfig changes
and a policy option in VM properties to specify whether you should
forcib=
ly proceed with reboot/shutdown when graceful methods fail/timeout
=20
is there anything not covered for a typical user?=20
I think you covered it all. Based on the original emails by Martin, I
presumed you only covered "warm" reboot, having "cold" reboot
available
as well is cool.
David
We intentionally don't want to provide all possible options, just
those m=
aking sense. The feature is about providing a convenient shortcut.

Thanks,
michal
