Qemu Networking Setup

Install qemu and some utilities as following:

sudo apt-get install bridge-utils libvirt-bin virt-manager vde2 qemu qemu-common qemu-kvm qemu-utils
sudo setcap cap_net_admin=ei $(ls /usr/bin/qemu-system-x86_64 /usr/bin/qemu 2>/dev/null)

Modify the file /etc/network/interfaces in such a way (eth0 parameters will be moved into br0):

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

auto br0
iface br0 inet static
        address 10.0.0.3
        network 10.0.0.0
        netmask 255.255.0.0
        broadcast 10.0.255.255
        dns-search mylan.local
        dns-nameservers 10.0.1.2 8.8.8.8
        #append domain-name-servers 10.0.1.2 8.8.8.8
        #supersede domain-name-servers 10.0.1.2 8.8.8.8
        gateway 10.0.1.1
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0
        bridge_maxwait 0

Modify (or create) the file /etc/resolvconf/resolv.conf.d/tail as following:

nameserver 10.0.1.2
nameserver 8.8.8.8
