[one-users] Problem with network

Mon May 17 08:13:27 PDT 2010

I tried your link but the file  /etc/udev/rules.d/70-persistent-net.rules is
empty. I also tried adding the INPUT and GRAPHICS options in the template
but i still cant connect to the vm (i used vncviewer localhost).

As I previously wrote, is it correct my network configuration? I have to use
192.168.122.0 network for my VMs because the IP of the bridge is
192.168.122.1 or i can use other ip (ES:10.0.0.0)? I added few lines in the
vmcontext.sh file to log the ip and mac used but when i shoutdown the vm and
launch manually with qemu i see no changes in the filesystem (i've a doubt
that the state running means that the vm is not running for real...).
