qemu: Avoid sending STOPPED event twice
In some circumstances, libvirtd would issue two STOPPED events after it stopped a domain. This was because an EOF event can arrive after a qemu process is killed but before qemuMonitorClose() is called. qemuHandleMonitorEOF() should ignore EOF when the domain is not running. I wasn't able to reproduce this bug directly, only after adding an artificial sleep() into qemudShutdownVMDaemon().
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.
