Re: [Xen-devel] Re: xm list dropping domain?
Thanks for the information Mike,
I supposed it was getting destroyed, hmm. I'm making the controller
part of a grid service and the VM's are distinguished by an assigned
distinguished name which maps to a local name (so that ID #s can
change). The controller is only dealing in local names now. It looks
like one of the domain events is restart:
(event xend.domain.exit (gridvm1 3 reboot))
(event xend.domain.restart (gridvm1 3 schedule))
(event xend.domain.destroy (gridvm1 3))
(event xend.domain.died (gridvm1 3))
(event xend.domain.restart (gridvm1 3 begin))
(event xend.domain.create (gridvm1 3))
(event xend.domain.restart (gridvm1 3 success))
(event xend.domain.unpause (gridvm1 3))
..where "gridvm1" is the local name. So I don't think a domain object
is necessary, couldn't I poll 8001 for any changes concerning the local
name (as long as nothing at a higher level started a domain with the
same name in that window)?. That's pretty cool, I didn't know you could
receive the events, I thought you could only 'ask.'
That makes me think I should write a polling thread that any class could
register callbacks with? My thinking is that the 'right way' is to
decouple any higher level functionality. Unless I'm missing a
programming trick here..

Thanks, I would definitely like to take a look. I started an http
interface, but I do need to think about all of this some more (if I
combined or made improvements I'd make that available to anyone also).
Thanks to you both for you help!
