RE: [Xen-users] State of a rebooting vm

        Actually, when a VM is rebooted, it is destroyed and a new one is
created.  This should only take as long as a destroy and create would take
on the command line.  The only way to determine how long it took or when it
happened would be to look at the appropriate line(s) in the appropriate
logs.  I'm not an expert here and can't tell you where to look, and in
reality, I am simply making an assumption that is the opposite of Simons.
My reasoning for this assumption is as follows:
1) The VM ID in xm list changes 
2) The cpu time counter in xm list resets
        I can't tell you which log(s) to look in to figure out what you
want, but I should imagine it is possible.

Firstly, that fact that your question wasn't answered probably means 
that no-one has the answer - just asking again isn't the best way to 
go about things.

As far as I know, the VM remains running when a guest is rebooting - 
but I'm no expert.

WANTED: "Software CD ROM Kit" for Canon CLBP 360-PS printer (Canon 
part no RH6-3612, or possibly RH6-3810, or RH6-3610 might do). I've a 
dead HD and need this CD so I can replace the disk and re-install the 
printer OS on it.
This is NOT the same thing as the printer drivers to load on the 
computer - there's no problem there.
If anyone knows where I might get hold of one I'd be grateful - 
requests to Canon drew a blank, it's been out of support for years.
Alternatively, if anyone has one of these and would let me image 
their hard disk ...
