The qemu side is not merged in yet, so there is a chance that the interface will change. Don't detect the capability just yet then.

If 1) dbus-vmstate is required for migration of a domain using a slirp-helper and 2) we enable this automatically for existing XML configs with <interface type='user'/> if a) QEMU has QEMU_CAPS_NET_SOCKET_DGRAM b) the slirp-helper process is installed on the system then we've effectively made their machines unmigratable So if we want to enable it automatically, we should add: c) QEMU has QEMU_CAPS_DBUS_VMSTATE regardless of whether dbus-vmstate gets merged into QEMU until libvirt's next release Jano
