Re: AW: [Xen-users] lspci in domU shows nothing

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

You shouldn't see any PCI devices in lspci if you're in a paravirt domU.  In 
an HVM (full virtualisation) domU you will see output from lspci.

HVM has to fake out a real PC so the guest OS won't know it's being 
virtualised; real PCs always have pci, so it has to fake a PCI bus ;-)

PV guests know they're running on Xen, so none of this faking-out is needed.  
They don't get given any fake PCI devices because it's not needed to make 
them happy ;-)

What you've observed in lspci output is perfectly normal, nothing to worry 
about :-)

Cheers,
Mark
