RE: [Xen-devel] [PATCH] Minor fix to xentop to stop it dying when domains go away at the wrong time

["Graham, Simon" <Simon.Graham@xxxxxxxxxxx>]

OK - I've reworked the fix to put it in libxenstat -- still not
completely convinced I like it, but take a look and let me know what you
think - as you suggested, I've made the collectors return a value
indicating if a fatal error occurred (-ve), a retryable error occurred
(0) or they were successful (+ve) and put in code to retry from the top
when a retryable error occurs (with a small 1/4s delay so we don't spin
wildly whilst things stabilize).

-----------------------------------------------------------

Currently, xenstat_get_node exits with a failure if a VM is deleted
between the time
it gets the list of VMs and the time it queries xenstore for it's name
and other
parameters. This patch modifies xenstat_get_node to retry the process
from scratch
if a recoverable error occurs.

Note that the patch supplied is against 3.0.testing although I think
unstable is basically the same.
