PCI pass-thru). That is correct - once the host device enumeration stuff is done we'll be in a better position to address this limitation, because we'll at least be able to figure what devices are available for passthrough. Passthrough in Xen at least is quite a complex thing requiring multiple admin steps outside the context of the guest config file which makes it rather unpleasant to deal with. I'm honestly not sure how this will map into the API, because I'd rather like this steps to not be exposed to users. > You should be able to do this by starting the domain using an ordinary > Xen configuration file. It also needs manual setup of the pciback driver & steps to hide the device from the host drivers.
