As I published in my previous post, I installed Virtual Box 1.5.
Now that I am using it, I found a couple of problems. First, I wanted to copy the virtual disks (VDI), and to my surprise, to copy the files just won't do the trick. We must use the disks cloning tool, as in the following example:
VBoxManage clonevdi source.vdi destination.vdi
The next problem I had is that the network didn't work in 'Host Interface'. After looking at the help, and a few rounds with google, ubuntuforums and etcetera, I found a way to make it work. Here's a mini howto.
First we install necessary packages:
sudo apt-get install bridge-utils
sudo apt-get install uml-utilities
Then we must define network interfaces. We edit the interfaces file:
sudo gedit /etc/network/interfaces
We add the necessary interfaces (replacing 'user' for the user that will use the virtual machines, and obviously a correct IP):
iface br0 inet dhcp
bridge_ports eth0 br0
iface tap0 inet manual
up ifconfig $IFACE 192.168.0.150 up
down ifconfig $IFACE down
We restart the network:
sudo /etc/init.d/networking restart
We add the user to the uml-net group:
sudo gpasswd -a user uml-net
According to the help, this shoud work, but no. I found that for this to work we must execute:
sudo chmod 0666 /dev/net/tun
sudo chmod 0666 /dev/vboxdrv
After this, we may set 'Host Interface', and in the interface name we enter 'tap0'.
And that's it.
