Xen devel - Nov 2013 - Change on_poweroff while domain is running

Hello,

Is it possible to change the ''on_poweroff'' attribute while a
domain is running?
That is, without having to destroy the instance and creating it again.

Best regards,
Jose

Using xl, not currently AFAIK.

I can see how this might be useful though, so it''s is something we
could
consider for 4.5, patches welcomed. I''d think that stashing the setting
in xenstore and providing a command to change it, with the attendant
watches in the xl monitoring daemon would be the way to go.

It might also be useful to have a mechanism to have xl start monitoring
a domain which it didn''t just create, which would allow the daemon to
be
restarted e.g. on upgrade.
