qemu with network

[Juraj Fedel <w4m@inmail.sk>]

I am having troubles with useing tun/tap network with qemu.
If I start qemu as ordinary user it complains that it can not
connect to tun device. If I run it with 'sudo qemu' it create
tun0 network device and than I can connect to virtual system.
$ ls -l /dev/net/tun
crw-rw----  1 root root 10, 200 2005-07-12 14:09 /dev/net/tun
Should I change permisson or owner or what to make it usable as
non priviledged user?

Another question is how do I start second (or more) qemu
and make them apear as to be connected to the same tun0
device so two virtual computers can talk to each other?

Thanks
Juraj
