Curious, if libvirt auto discover a bunch of pci devices on the host, should agent report all of them to user/admin? If not, based on what kind of criteria to filter pci devices? > imagine it will be available in the Ubuntu 14.04 release as well, assuming > they're targeting current versions. > > On Thu, Feb 13, 2014 at 1:21 PM, Edison Su <edison...@citrix.com> wrote: > > Hi Ryousei, > > The patch sounds good to me, don’t know why it’s not got checked into > 4.2 or 4.3.
