The libvirtd daemon uses systemd-machined D-Bus API when manipulating
domains. The systemd-machined is D-Bus activated on demand.
However, during system shutdown systemd-machined is stopped concurrently
with libvirtd and virsh users also doing their final cleanup may
transitively fail due to unavailability of systemd-machined. Example
error message
> libvirtd[1390]: 2017-12-20 18:55:56.182+0000: 32700: error : virSystemdTerminateMachine:503 : Refusing activation, D-Bus is shutting down.
To circumvent this we need to explicitly specify both ordering and
requirement dependency (to avoid late D-Bus activation) on
systemd-machined. See [1] for the dependency debate.

We recently added a generic XHCI USB3 controller to QEMU, and libvirt
supports adding that controller rather than the NEC XHCI USB3
controller, but when auto-adding a USB controller to Q35 domains we
were still adding the vendor-specific NEC controller. This patch
changes to add the generic controller instead, if it's available in
the QEMU binary that will be used.

qemuDomainDefValidateVideo() (called from qemuDomainDefValidate()) is
just a loop performing various checks on each video device. Rather
than maintaining this separate function, just fold the validations
into qemuDomainDeviceDefValidateVideo(), which is called once for each
video device.
Commit 10c73bf1 fixed a bug that I had introduced back in commit
70249927 - if a vhost-scsi device had no manually assigned PCI
address, one wouldn't be assigned automatically. There was a slight
problem with the logic of the fix though - in the case of domains with
pcie-root (e.g. those with a q35 machinetype),
qemuDomainDeviceCalculatePCIConnectFlags() will attempt to determine
if the host-side PCI device is Express or legacy by examining sysfs
based on the host-side PCI address stored in
hostdev->source.subsys.u.pci.addr, but that part of the union is only
valid for PCI hostdevs, *not* for SCSI hostdevs. So we end up trying
to read sysfs for some probably-non-existent device, which fails, and
the function virPCIDeviceIsPCIExpress() returns failure (-1).
By coincidence, the return value is being examined as a boolean, and
since -1 is true, we still end up assigning the vhost-scsi device to
an Express slot, but that is just by chance (and could fail in the
case that the gibberish in the "hostside PCI address" was the address
of a real device that happened to be legacy PCI).
Since (according to Paolo Bonzini) vhost-scsi devices appear just like
virtio-scsi devices in the guest, they should follow the same rules as
virtio devices when deciding whether they should be placed in an
Express or a legacy slot. That's accomplished in this patch by
returning early with virtioFlags, rather than erroneously using
hostdev->source.subsys.u.pci.addr. It also adds a test case for PCIe
to assure it doesn't get broken in the future.
Commit 8708ca01c added virNetDevSwitchdevFeature() to check if a network
device has Switchdev capabilities. virNetDevSwitchdevFeature() attempts
to retrieve the PCI device associated with the network device, ignoring
non-PCI devices. It does so via the following call chain
virNetDevSwitchdevFeature()->virNetDevGetPCIDevice()->
virPCIGetDeviceAddressFromSysfsLink()
For non-PCI network devices (qeth, Xen vif, etc),
virPCIGetDeviceAddressFromSysfsLink() will report an error when
virPCIDeviceAddressParse() fails. virPCIDeviceAddressParse() also
logs an error. After commit 8708ca01c there are now two errors reported
for each non-PCI network device even though the errors are harmless.
To avoid the errors, introduce virNetDevIsPCIDevice() and use it in
virNetDevGetPCIDevice() before attempting to retrieve the associated
PCI device. virNetDevIsPCIDevice() uses the 'subsystem' property of the
device to determine if it is PCI. See the sysfs rules in kernel
documentation for more details

This is a variant of Nehalem with indirect branch prediction protection.
The only difference between Nehalem and Nehalem-IBRS is the added

Thus the diff matches QEMU, but the new CPU model itself is different.
The QEMU's versions of both models contain "vme" feature, while this
feature is missing in libvirt's models. While we can't change the
existing Nehalem CPU model, we could add "vme" to Nehalem-IBRS to make
it similar to QEMU, but doing so would fool our CPU detecting code so
that any Nehalem CPU with "vme" feature would be detected as
Nehalem-IBRS CPU without spec-ctrl. Not adding "vme" to Nehalem-IBRS is
safe as QEMU will just provide the feature anyway, which matches what
happens with Nehalem (and new enough machine types).
