Hi !

> 1) Refuse to install if there are DomU's running; or

That's probably the 'safe way'.

The 'xendomains stop' usualy saved the state of the DomU's in a file
(at least on our end).

Will Xen 4.3 after reboot be able to read those state-files so the
DomU's will only have a small window of unavailability without having
to restart?

bye,
Chris
