Hi Martin,
there may be more kinds of reboot in context of RHEV: "warm" reboot that
keeps qemu process intact, or "cold" that would involve qemu process
termination and start of new one - and this could be done with keeping
of current configuration, or with applying settings that "take effect
after reboot" that have changed during VM runtime; and all of these can
be "soft" - when the guest OS reboots itself and "hard" when you
perform
the reboot right away.
we plan to have 2 of them which seem to make most sense
"warm" without applying config changes and keeping qemu process (i.e. also keeps
Run Once,Stateless, pooled VM config/state)
"cold" which kills qemu and is completely driven by Engine, and applies config
changes
and a policy option in VM properties to specify whether you should forcibly proceed with
reboot/shutdown when graceful methods fail/timeout
is there anything not covered for a typical user? We intentionally don't want to
provide all possible options, just those making sense. The feature is about providing a
convenient shortcut.
Thanks,
michal
All of these have their use cases, so it should be documented what will
you implement, and you may expect somebody asking you to implement the
rest. ;)
