qemu: support new pci controller model "pcie-root-port" This is backed by the qemu device ioh3420. chassis and port from the <target> subelement are used to store/set the respective qemu device options for the ioh3420. Currently, chassis is set to be the index of the controller, and port is set to "(slot << 3) + function" (per suggestion from Alex Williamson).

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>

test: fix pcie-root-port-too-many test While reviewing a patch from Andrea that modified this test case, I realized that although it was "properly failing" (it's a negative test), that it was failing for the wrong reason (the MULTIFUNCTION cap wasn't set in the test case, so it was saying that multifunction=on wasn't supported by the QEMU binary; instead it should have been complaining that it had run out of PCI slots of the appropriate type and couldn't automatically add any more). This improper failure had started when I added the patch to automatically aggregate pcie-root-ports onto multiple functions of each pcie-root slot, but I hadn't noticed it because the test still failed. This patch corrects the test case to 1) set the MULTIFUNCTION flag in the caps, and 2) attempt to add 241 pcie-root-ports to a domain. Since there are 30 slots available on a pcie-root (slot 0 is reserved, and slot 31 is used by the integrated SATA controller), and a pcie-root-port can only be placed on a function of a slot on pcie-root, the maximum number of pcie-root-ports in any domain is 240.

qemu: support new pci controller model "pcie-root-port" This is backed by the qemu device ioh3420. chassis and port from the <target> subelement are used to store/set the respective qemu device options for the ioh3420. Currently, chassis is set to be the index of the controller, and port is set to "(slot << 3) + function" (per suggestion from Alex Williamson).

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>
