5 p.m.
I am observing a crash with libvirt ruby bindings. Please see stack
trace below. I am using libvirt-0.4.2 and ruby-libvirt-0.0.6. I have
upgraded to new versions of both today, so I am not sure which one is
to blame. The problem happening when I try to do domain shutdown.
I can reproduce the problem, so if somebody will be looking into that,
I can aid debugging it.
Sincerely,
Vadim
