Add role parameter NovaLibvirtNumPciePorts which sets `libvirt/num_pcie_ports`
|
|
to specify the number of PCIe ports an instance will get.
|
|
Libvirt allows a custom number of PCIe ports (pcie-root-port controllers) a
|
|
target instance will get. Some will be used by default, rest will be available
|
|
for hotplug use. When using the 'q35' machine type, by default, it allows only
|
|
a *single* PCIe device to be hotplugged. And Nova currently sets
|
|
'num_pcie_ports' to "0" (which means, it defaults to libvirt's "1"), which is
|
|
not sufficient for hotplug use.
|
|
Default for NovaLibvirtNumPciePorts is 16.
