QEMU with network boot

[Edwin Groothuis]

Hello,

First time user with QEMU, trying to get things up and running...

I got routing working, I can reach the internet from my emulated
FreeBSD 6.3 OS. Thanks to nox on #bsdports for that.

When I start the qemu host with "-boot n", I see the DHCP requests
and answers going over the wire (... tap device ...) but the NIC
keeps saying that it can't get an IP address. This is the network
output of it:

It is giving option 150, which I don't really know what for.
And it is asking for vendor specific information, which I don't
really know which one that is neither.

Has anybody managed to get this working? How did the relevant part
of your dhcp.conf look like?
