xen_platform_pci=1
This setting is not supported in the libvirt libxl driver, but AFAICT libxl sets the default to 'true' for HVM guests.
pci_msitranslate=1
This is also not supported in libvirt and unfortunately defaults to 'false'.
pci_permissive = 1
Patches have been submitted for this setting but so far there has not been agreement on the schema change

thats bad :(
max_grant_frames = "128
This, along with max_event_channels, is supported as an attribute on the xenbus controller, e.g.
<controller type='xenbus' maxGrantFrames='128' maxEventChannels='2047'/>
yep I know but why does virsh not translate it from xen-xm->xml?
and the pci passthrough devices are not there...
Is setting maxGrantFrames (and possibly maxEventChannels) on the xenbus controller enough to see the devices in the guest?
no and I know these settings are suported but here the same, why does virsh not translate it?
