Each qemu process manages exactly one VM, so qemu doesn't care what id a guest has. Higher-level management software, such as libvirt, has notions of a VM name and UUID (both of which can be specified on the command line parameters given to qemu, and the UUID can even be propagated to the guest, such as by SMBIOS readable by dmidecode in the guest), as well as a VM id (in libvirt's case, a sequentially increasing number for each VM that libvirt spawns a qemu process for). But that's getting outside the realm of qemu, since qemu doesn't care what name or uuid you picked, only whether you have access to the monitor of the qemu process. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
