[Xen-devel] Is there a way to get notification, when a domain shutdown/restarts
Hi, I would like to write a script, which will run, every time my (specific) domain reboots or shutdown. Is there any way, to "catch" those events, or to be notified when it happens?

There should be some method to be called every time the domain reboots/shuts down. There you can add a call to you script or write it purely in python. I think it''s somewhere in XendDomainInfo.py file somewhere in python site-packages directory.

Well, i was looking for a solution, which won''t require me to modify teh code, but to use an already-built mechaism for this, but i guess none exists, so i''ll modify the code for this. Thanks!

You could use something like the monit package to monitor the domU through a variety of methods, ping, socket connect, etc. The config allows one to specify multiple rules to detect and take action based upon events. It would be trivial to monitor a domU via ping and restart it if it stopper responding. It''s also less code you have to maintain yourself :-) -Bruce On Mon, Sep 21, 2009 at 4:25 AM, Tom Rotenberg <tom.rotenberg@gmail.com>wrote:> Well, i was looking for a solution, which won''t require me to modify > teh code, but to use an already-built mechaism for this, but i guess > none exists, so i''ll modify the code for this. > > Thanks! > > > On Fri, Sep 18, 2009 at 5:01 AM, Michal Novotny <minovotn@redhat.com> > wrote: > > On 09/16/2009 03:51 PM, Tom Rotenberg wrote: > >> > >> Hi, > >> > >> I would like to write a script, which will run, every time my > >> (specific) domain reboots or shutdown.
