Re: [Xen-devel] Is it possible to follow a rebooted domain (with a different ID)?



Xenstore will keep track of the name of the domain, which has to be
unique, so you should be able to "find" your domain again by looking for
its name. I've just reinstalled everything on my test-box, so I can't
look at exactly where the name is stored [I don't have any VM's on
there!], but I think you can figure it out yourself with a bit of
"xenstore-ls".
[...]
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)?
You can have a xenstore watch for that.

I was looking at some code that does that the other day in xenconsoled
[it watches for "new domain appearing"]. Have a look at
xen/tools/console/daemon/io.c (I think!)

Thank you for all the replies, I appreciate your help! I'll look those up.

Thanks,
Razvan Cojocaru
