qemu: command: Override HOME variable for system QEMU By default, qemu user's home dir points to '/' which shouldn't be used at all. We therefore pass the HOME variable from the current variable iff not running as SUID, which means that for systemd we never set it. This patch makes sure, that for system QEMU this is always set to libDir/<driver>, session mode is left untouched. Signed-off-by: Erik Skultety <eskultet@redhat.com> Reviewed-by: Daniel P.

qemu: Store default CPU in domain XML When starting a domain without a CPU model specified in the domain XML, QEMU will choose a default one. Which is fine unless the domain gets migrated to another host because libvirt doesn't perform any CPU ABI checks and the virtual CPU provided by QEMU on the destination host can differ from the one on the source host. With QEMU 4.2.0 we can probe for the default CPU model used by QEMU for a particular machine type and store it in the domain XML. This way the chosen CPU model is more visible to users and libvirt will make sure the guest will see the exact same CPU after migration. Architecture specific notes - aarch64: We only set the default CPU for TCG domains as KVM requires explicit "-cpu host" to work. - ppc64: The default CPU for KVM is "host" thanks to some hacks in QEMU, we will translate the default model to the model corresponding to the host CPU ("POWER8" on a Power8 host, "POWER9" on Power9 host, etc.). This is not a problem as the corresponding CPU model is in fact an alias for "host". This is probably not ideal, but it's not wrong and the default virtual CPU configured by libvirt is the same QEMU would use. TCG uses various CPU models depending on machine type and its version. - s390x: The default CPU for KVM is "host" while TCG defaults to "qemu". - x86_64: The default CPU model (qemu64) is not runnable on any host with KVM, but QEMU just disables unavailable features and starts happily. https://bugzilla.redhat.com/show_bug.cgi?id=1598151 https://bugzilla.redhat.com/show_bug.cgi?id=1598162 Signed-off-by: Jiri Denemark <jdenemar@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>

qemu: Use memory-backend-* for regular guest memory So far, Libvirt configures memory-backend-* for memory hotplug, possibly NUMA nodes and in a few other cases. This patch switches to constructing the memory-backend-* command line for all cases. To keep ability to migrate guests a little hack is used: the ID of the object is set to the one that QEMU uses internally anyways. These IDs are stable (first started to appear somewhere around v0.13.0-rc0~96) and can't change. In fact, this patch does exactly what QEMU does internally. The reason for moving the logic into Libvirt is that QEMU wants to deprecate the old style of specifying memory. So far, only x84_64 test cases are changed, because tests for other architectures use older capabilities, which still lack the QEMU_CAPS_MACHINE_MEMORY_BACKEND capability and they don't report the RAM ID.

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.
