Bug Description
Binary package hint: libvirt-bin
Quoting Daniel P. Berrange:
> The core problem was that the event loop was getting confused when we
> removed a monitored file handle. It would then start running the wrong
> event handler callbacks. So the xenstore watch handler got called even
> though no watch was pending :-( This also caused clients to get stuck
> because the watch detecting end-of-file on the socket wasn't getting
> called.
The patch at
http://
fixes this repeatable problem both in my stress-testing of libvirtd, and in
upstream testing of libvirt-cim by Daniel Veillard.
This bug is serious enough that it should be included in Jaunty.
