Peter Krempa	e546785dce	tests: qemuxml2argv: Make tests based on DO_TEST_CAPS_LATEST stable ... To avoid problems with test cases specifying an alias machine type which would change once capabilities for a newer version are added strip all alias machine types for the DO_TEST_CAPS_LATEST based tests.

Daniel P. Berrangé	30fb2276d8	qemu: support passing pre-opened UNIX socket listen FD ... There is a race condition when spawning QEMU where libvirt has spawned QEMU but the monitor socket is not yet open. Libvirt has to repeatedly try to connect() to QEMU's monitor until eventually it succeeds, or times out. We use kill() to check if QEMU is still alive so we avoid waiting a long time if QEMU exited, but having a timeout at all is still unpleasant. With QEMU 2.12 we can pass in a pre-opened FD for UNIX domain or TCP sockets. If libvirt has called bind() and listen() on this FD, then we have a guarantee that libvirt can immediately call connect() and succeed without any race. Although we only really care about this for the monitor socket and agent socket, this patch does FD passing for all UNIX socket based character devices since there appears to be no downside to it. We don't do FD passing for TCP sockets, however, because it is only possible to pass a single FD, while some hostnames may require listening on multiple FDs to cover IPv4 and IPv6 concurrently.

John Ferlan	87973a45f9	qemu: Add VM Generation ID to qemu command line ... https://bugzilla.redhat.com/show_bug.cgi?id=1149445 If the domain requests usage of the genid functionality, then add the QEMU '-device vmgenid' to the command line providing either the supplied or generated GUID value. Add tests for both a generated and supplied GUID value. Signed-off-by: John Ferlan <jferlan@redhat.com> ACKed-by: Michal Privoznik <mprivozn@redhat.com>	2018-05-25 08:15:58 -04:00
