Bug Description
It looks like the libvirtd daemon is leaking file descriptors to the logfile that it sets up for each VM. I've attached a typescript showing the symptom (start vm, inspect lsof, stop vm, inspect lsof, start vm, inspect lsof, stop vm, inspect lsof), note that the descriptors referring to the VM logfiles are never closed. After a thousand or so VMs, the daemon stops accepting new VM creation events until libvirtd is restarted.
