Then I've got one more question. As far as I know, passthrough device can be assigned to only one single guest. right?

But what if multiple guest OS's need that passthrough device? Can we make it happen to passthrough a single device to multiple guest OS's?

It sounds like what you want is to give the guest direct access to the wifi adapter. You'll need to pass it through rather than bridging the NIC. PCI passthrough should work if you have the compatible hardware, and USB passthrough may work as well (though I've never tried that with a wireless adapter).

Hello folks,

I'm wondering why Xen doesn't provide WiFi interface for guest OS.

I can only find rtl8139, e1000 kind of wired ethernet interfaces.

Here is a thing.

My system has a WiFi interface on host and have no problem to make guest OS's leverage Host-side WiFi interface for their internet connection.

But in this case, guest OS's always have only ethernet interface.

The reason why I'm trying to figure out how to make guest OS's have a WiFi interface is to make guest OS's being able to scan WiFi access points

Just like the guest OS has an actual WiFi interface. Somehow different from network bridge through WiFi.

Any brilliant tip?

Cheers,

Nate
