      docs: Clarification for when allowed to use 'lun' for "volume" · 91b96438
      由 John Ferlan 提交于 
      While re-reading what I wrote for commit id '785a8940', I realized
I needed to clarify that being able to present as a 'lun', the mode
property for the pool source element needed to be "host" (or empty)
and not "direct".

It was described correctly later in the mode host description, but
this just ensures it's not missed here as well.

      docs: document when pcie-root/dmi-to-pci-bridge support was added · 10e207bb
      由 Laine Stump 提交于 
      Also move the mention of version numbers for the various PCI
controller models up to the end of the sentence where they are first
given, to avoid confusion.

      qemu: ignore assumptions about hotplug requirement when address is from config · 9a12b6cd
      由 Laine Stump 提交于 
      Certain PCI buses don't support hotplug, and when automatically
assigning PCI addresses for devices, libvirt is very conservative in
its assumptions about whether or not a device will need to be
hotplugged/unplugged in the future. But if the user manually assigns
an address, they likely are aware of any hotplug requirements of the
device (or at least they should be).

In short, after this patch, automatically PCI address assignment will
assume that the device must be plugged in to a hot-pluggable slot, but
manually assignment can place the device in any bus that is
compatible, regardless of whether or not it supports hotplug. If the
user makes a mistake and plugs the device into a bus that doesn't
support hotplug, then later tries to do a hot-unplug, qemu will give
an appropriate error.

(in the future we may want to add a "hotpluggable" attribute to all
devices, with default being "yes" for autoassign, and "no" for manual
assign).

      qemu: always permit PCI devices to be manually assigned to a PCIe bus · 1e15be1b
      由 Laine Stump 提交于 
      When support for the pcie-root and dmi-to-pci-bridge buses on a Q35
machinetype was added, I was concerned that even though qemu at the
time allowed plugging a PCI device into a PCIe port, that it might not
be supported in the future. To prevent painful backtracking in the
possible future where this happened, I disallowed such connections
except in a few specific cases requested by qemu developers (indicated
in the code with the flag VIR_PCI_CONNECT_TYPE_EITHER_IF_CONFIG).

Now that a couple years have passed, there is a clear message from
qemu that there is no danger in allowing PCI devices to be plugged
into PCIe ports. This patch eliminates
VIR_PCI_CONNECT_TYPE_EITHER_IF_CONFIG and changes the code to always
allow PCI->PCIe or PCIe->PCI connection *when the PCI address is
specified in the config. (For newly added devices that haven't yet
been given a PCI address, the auto-placement still prefers using the
correct type of bus).

      qemu: refactor qemuBuildControllerDevStr to eliminate future duplicate code · 1074fc50
      由 Laine Stump 提交于 
      The PCI case of the switch statement in this function contains another
switch statement with a case for each model. Currently every model
except pci-root and pcie-root has a check for index > 0 (since only
those two can have index==0), and the function should never be called
for those two anyway. If we move the check for !pci[e]-root to the top
of the pci case, then we can move the check for index > 0 out of the
individual model cases. This will save repeating that check for the
three new controller models about to be added.
