NetBSD as virtual machine in KVM

[Goran <netbsd-list%arcor.de@localhost>]

Hi all!

I'm new to this list and to NetBSD too.

I've started to install NetBSD without problems inside a virtual machine
with KVM on Linux (Ubuntu 7.04).

After that I configured NetBSD to use dhcp for the one and only NIC
"ne1". And there comes my first problem:

Mar  8 23:32:26 crusty /netbsd: ne1: device timeout

I've started NetBSD with:

kvm -m 512 -net nic,model=ne2k_isa -net user -hda Desktop/netbsd.img

With this command I usually start my virtual machines. Dhcp and routing
is automatically enabled by kvm. But inside my virtual NetBSD machine
dhclient tolds:

DHCPDISCOVER on ne1 to 255.255.255.255 port 67 intervall 5
DHCPDISCOVER on ne1 to 255.255.255.255 port 67 intervall 14
DHCPDISCOVER on ne1 to 255.255.255.255 port 67 intervall 9
DHCPDISCOVER on ne1 to 255.255.255.255 port 67 intervall 3
No DHCPOFFERS received.

What should I do to enable networking in my virtual NetBSD machine?

Thanks in advance,
Goran
