Subject: Is it possible to follow a rebooted domain (with a different ID)?
Date: Mon, 07 Jan 2013 12:48:28 +0200 [thread overview]
Message-ID: <50EAA7FC.1090602@gmail.com> (raw)
Hello,
I have an application, running in dom0 userspace, that receives
mem_events about a domU HVM guest. At some point, the HVM guest (a
Windows machine) restarts, at which point I need to shut down my
userspace application, find it's new ID (with 'xm list'), then re-start
my application passing the new ID as a parameter.
What I'd like to be able to do is to automatically follow the domain
after it has started again. Is it possible to do this from dom0
userspace (using libxc), and if it is, how?
A related question is this: is it possible to get notifications from
userspace about a new domU that's just been started (regardless of
whether it's a reboot of a previously watched domU or not)?
Thanks,
Razvan Cojocaru
