If a client disconnects while it has a stream active, there is a race condition which could see libvirtd crash. This is because the client struct may be freed before the last stream event has triggered. This is trivially solved by holding an extra reference on the client for the stream callbak * daemon/stream.c: Acquire reference on client when adding the stream callback
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.
