qemu: add dmi-to-pci-bridge controller This PCI controller, named "dmi-to-pci-bridge" in the libvirt config, and implemented with qemu's "i82801b11-bridge" device, connects to a PCI Express slot (e.g. one of the slots provided by the pcie-root controller, aka "pcie.0" on the qemu commandline), and provides 31 *non-hot-pluggable* PCI (*not* PCIe) slots, numbered 1-31. Any time a machine is defined which has a pcie-root controller (i.e. any q35-based machinetype), libvirt will automatically add a dmi-to-pci-bridge controller if one doesn't exist, and also add a pci-bridge controller. The reasoning here is that any useful domain will have either an immediate (startup time) or eventual (subsequent hot-plug) need for a standard PCI slot; since the pcie-root controller only provides PCIe slots, we need to connect a dmi-to-pci-bridge controller to it in order to get a non-hot-plug PCI slot that we can then use to connect a pci-bridge - the slots provided by the pci-bridge will be both standard PCI and hot-pluggable. Since pci-bridge devices themselves can not be hot-plugged into a running system (although you can hot-plug other devices into a pci-bridge's slots), any new pci-bridge controller that is added can (and will) be plugged into the dmi-to-pci-bridge as long as it has empty slots available. This patch is also changing the qemuxml2xml-pcie test from a "DO_TEST" to a "DO_DIFFERENT_TEST". This is so that the "before" xml can omit the automatically added dmi-to-pci-bridge and pci-bridge devices, and the "after" xml can include it - this way we are testing if libvirt is properly adding these devices.

tests: unify qemu binary paths for all qemu related tests Our test data used a lot of different qemu binary paths and some of them were based on downstream systems. Note that there is one file where I had to add "accel=kvm" because the qemuargv2xml code parses "/usr/bin/kvm" as virt type="kvm". Signed-off-by: Pavel Hrdina <phrdina@redhat.com>

tests: qemuxml2xml: assign device addresses We use the PreFormat callback for this. Many test cases need to be extended to pass in proper qemuCaps flags so AssignAddresses doesn't throw errors. One test case (pcie-root-port-too-many) is dropped, since it was meant only for checking an error condition in qemuxml2argv, and one we add in AssignAddresses it errors here too. Long term I think AssignAddresses should be handled in qemu's PostParse callback, but that's not entirely straightforward. Handling it here means we can get the test suite churn over with.

device: cleanup input device code The current code was a little bit odd. At first we've removed all possible implicit input devices from domain definition to add them later back if there was any graphics device defined while parsing XML description. That's not all, while formating domain definition to XML description we at first ignore any input devices with bus different to USB and VIRTIO and few lines later we add implicit input devices to XML. This seems to me as a lot of code for nothing. This patch may look to be more complicated than original approach, but this is a preferred way to modify/add driver specific stuff only in those drivers and not deal with them in common parsing/formating functions. The update is to add those implicit input devices into config XML to follow the real HW configuration visible by guest OS. There was also inconsistence between our behavior and QEMU's in the way, that in QEMU there is no way how to disable those implicit input devices for x86 architecture and they are available always, even without graphics device. This applies also to XEN hypervisor. VZ driver already does its part by putting correct implicit devices into live XML. Signed-off-by: Pavel Hrdina <phrdina@redhat.com>

qemu: populate <audio> element with default config Currently the QEMU driver secretly sets the QEMU_AUDIO_DRV env variable - VNC - set to "none", unless passthrough of host env variable is set - SPICE - always set to "spice" - SDL - always passthrough host env - No graphics - set to "none", unless passthrough of host env variable is set The setting of the QEMU_AUDIO_DRV env variable is done in the code which configures graphics. If no <audio> element is present, we now auto-populate <audio> elements to reflect this historical default config. This avoids need to set audio env when processing graphics.
