Hi Ben, Thanks for your insightful reply. Allow me to re-phrase my question. Hope you can comment further.
Basically, we have a need to run a application that needs a wifi interface in a virtual machine. You can think of the application as this command "iwlist eth1 scan". What this does is that it scans the airspace and lists all the networks(essid) it detects. Now if I want to run this command in a VM, the VM should see a wifi interface. This is my query. The virtual wifi interface must support the upward/downward movement of layer2 wifi frames. Can we have a wifi interface in a VM that can support queries like the above ? There is a physical wifi device at the host. I am thinking that just as Qemu links the virtual device to the actual nic card in the host, can it links the virtual wifi device to the actual wifi device ?

I have used qemu with -net user with my hosts' wifi interface. However, due to the nature of how wifi works, I think it would be impossible to setup a bridge (like you can do with a wired lan) and use the tap interface to provide full access to a qemu guest. One reason is one-to-one mapping between a wifi interface and it's AP. > Example: Qemu_VM could be configured to use wireless (in a different > subnet) while the host be on wired interface. I suspect that using a tap interface, and some ipfilt rules, you might be able to make this work. Assuming that the host doesn't have anything to do with that interface, you could write the ipfilt rules to push all the packets to the tap interface with a rewrite rule. However, I can't give you much help beyond that. I don't do ipfilt these days.
