KVM Guest Network

Network Tools

Get the good old ifconfig command back.

apt-get install net-tools

Network Interfaces

The new network naming scheme does not fit me. I rather like the good old ethX names. The new naming scheme makes a lot of considerations about the hardware before giving it a name, which sometimes results in very long and weird interfaces names. This especially happens when using USB network devices.

The first thing to do is to tell the kernel that we want the old naming scheme. Edit /etc/default/grub.

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

Make sure to update the grub configuration.

update-grub

Since we are changing a kernel parameter this calls for a reboot.
