I certainly do not expect a config file reload to terminate all active guests. Since QEMU is a full virt system, there is no graceful shutdown process, and so this is equivalent to ripping the power cable out of all your VMs. IMHO this makes SIGHUP essentially useless. We already have the ability to store a secondary config against any active guest VMs, which will be automatically activated upon next boot of the guest - this is how we let virDefineDomain() override the config of an existing VM. IMHO, sending SIGHUP to the daemon should just scan for config files and if any VMs are active, load into the secondary config.
