conf: Make specifying <memory> optional Now that the size of guest's memory can be inferred from the NUMA configuration (if present) make it optional to specify <memory> explicitly. To make sure that memory is specified add a check that some form of memory size was specified. One side effect of this change is that it is no longer possible to specify 0KiB as memory size for the VM, but I don't think it would be any useful to do so. (I can imagine embedded systems without memory, just registers, but that's far from what libvirt is usually doing). Forbidding 0 memory for guests also fixes a few corner cases where 0 was not interpreted correctly and caused failures. (Arguments for numad when using automatic placement, size of the balloon). This fixes problems described in https://bugzilla.redhat.com/show_bug.cgi?id=1161461 Test case changes are added to verify that the schema change and code behave correctly.

conf: add support for specifying CPU "dies" parameter Recently CPU hardware vendors have started to support a new structure inside the CPU package topology known as a "die". Thus the hierarchy is now: sockets > dies > cores > threads This adds support for "dies" in the XML parser, with the value defaulting to 1 if not specified for backwards compatibility. For example a system with 64 logical CPUs might report <topology sockets="4" dies="2" cores="4" threads="2"/> Reviewed-by: Jiri Denemark <jdenemar@redhat.com> Reviewed-by: Daniel Henrique Barboza <danielhb413@gmail.com> Signed-off-by: Daniel P.

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.

qemu: capabilities: Move setting QEMU_CAPS_DEVICE_VIDEO_PRIMARY to virQEMUCapsInitQMPBasicArch Until we clean up and remove all capabilities which no longer make sense to have separately, we should use virQEMUCapsInitQMPBasicArch to set the defaults as it's used by qemuxml2argvtest when testing with fake capabilities. This allows us to prevent testing dead code paths with the fake capability tests.
