Hello all,
I've searched for this error in several places but no luck.
I am trying to set up a virtual machine connected to a LAN out of the
computer running Netkit. I've followed the instructions in the FAQ and
either no tap is established or I get the error I include below.
Some things I've tried:
- Using eth0 for the tap (in the error below it's eth2, but it's the
same in both cases)
- Creating interfaces with the IP addresses in the host and the guest,
in the host but not the guest, the other way around and none of them.
- Using lab.conf and command 'vstart vm ...' below. With lab.conf, the
line that lstart uses is something like 'vstart vm
--eth2=tap10100101010002', that is, no commas nor dots.
Maybe I'm just missing something here. My Netkit version is as follows:
netkit at intersection-netkit:~$ /opt/netkit2/bin/vstart --version
vstart version 2.3
Netkit version: 2.4
Netkit kernel version: K2.3 (2.6.23.1)
Netkit filesystem version: F3.0a
Host kernel version: 2.6.24-16-generic
Also, my system information is:
netkit at intersection-netkit:~$ uname -a
Linux intersection-netkit 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42
UTC 2008 i686 GNU/Linux
It's a recently installed Kubuntu 8.04.
