Hi Jim,
i use libvirt 1.1.3.5 on fedora core 20, the vm´s i startet are xen-vm´s.
i also take a look on libvirt 1.1.2 on an openSuSE 13.1 und also on libvirt 1.0.2 on an OpenSuSE 12.3 and i didn´t see threads that are created and not closed . But on the openSuSE-Systems the vm´s are KVM/qemu.
on the fedora-system i will attach gdb to the libvirtd-process, and hope to see what´s doing on.
all the best
max
