Network

• Create bridge manually
  • Edit /etc/network/interfaces

auto veth0
iface veth0 inet static
 address 192.168.128.1
 netmask 255.255.255.0
 pre-up ip link add veth0 type veth peer name veth0p
 post-down ip link del veth0

auto br0
iface br0 inet static
 address 192.168.128.254
 netmask 255.255.255.0
 bridge_ports veth0p
 bridge_stp on
 bridge_maxwait 0
iface br0 inet6 auto

• Create a VM (using virt-manager) and joing its interface to the bridge (br0)

    <interface type='bridge'>
      <mac address='52:54:00:36:3e:86'/>
      <source bridge='br0'/>
      <model type='e1000'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
    </interface>
