Re: [PATCH] kvm tools: adds a PCI device that exports a host shared segment as a PCI BAR in the guest

[David Evensky <evensky@dancer.ca.sandia.gov>]

I don't know if there is a PCI card that only provides a region
of memory. I'm not really trying to provide emulation for a known
piece of hardware, so I picked values that weren't being used since
there didn't appear to be an 'unknown'. I'll ask around.
