[libvirt] [PATCH v3 2/4] qemu: assign virtio devices to PCIe slot when appropriate

Laine Stump laine at laine.org
Wed Aug 17 11:29:34 UTC 2016


libvirt previously assigned nearly all devices to a hotpluggable
legacy PCI slot even on machines with a PCIe root complex. Doing this
means that the domain will need a dmi-to-pci-bridge (to convert from
PCIe to legacy PCI) and a pci-bridge (to provide hotpluggable legacy
PCI slots.

To help reduce the need for these legacy controllers, this patch
checks for the QEMU_CAPS_VIRTIO_PCI_DISABLE_LEGACY capability (if that
capability is present, then all virtio devices will automatically
present as PCIe when attached to a PCIe controller, or PCI when
attached to a legacy PCI controller), and assigns virtio devices to a
hotpluggable PCIe slot instead.

NB: since the slot must be hotpluggable, and pcie-root (the PCIe root
complex) does *not* support hotplug, this means that suitable
controllers must also be in the config (i.e. either pcie-root-port, or
pcie-downstream-port). For now, libvirt doesn't add those
automatically, so if you put virtio devices in a config for a qemu
that has PCIe-capable virtio devices, you'll need to add extra
pcie-root-ports yourself. That requirement will be eliminated in a
future patch, but for now, it's simple to do this:

   <controller type='pci' model='pcie-root-port'/>
   <controller type='pci' model='pcie-root-port'/>
   <controller type='pci' model='pcie-root-port'/>
   ...
