Hey folks, I’m looking into what I would think would be a simple problem, but
is turning out to be more complicated than I would have anticipated. A
virtual machine managed by OpenNebula was blown away, but the backing RBD
images remain. Upon investigating, it appears
that the images still have watchers on the KVM node that that VM previously
lived on. I can confirm that there are no mapped RBD images on the machine and
the qemu-system-x86_64 process is indeed no longer running. Any ideas?
Additional details are below:
