[libvirt] [PATCH 0/2] nodedev: fix virtual_functions element

[Laine Stump]

Moshe Levi pointed out yesterday in an email to libvir-list that there
was no way to tell from the node device API that a PCI was capable of
having SRIOV virtual functions (VFs) if it was currently setup to not
have any:

 https://www.redhat.com/archives/libvir-list/2015-November/msg00894.html

These two patches modify the node device XML in two ways:

1) if the device has a file called sriov_totalvfs, the value contained
in that file will be included in the capabilities element as the
attribute "maxCount".

2) in this case, even if there are currently no VFs active/visible for
the device, the virtual_functions capability will still be reported.

  conf: support reporting maxCount attribute for virtual_functions cap
  nodedev: report maxCount for virtual_functions capability
