There are several ways to connect a virtual machine included in a VNX scenario to an external network:
Option 1: Bridge associated with external interfce (recomended)
- Create a virtual bridge associated with external interface (eth0 in this example). For example, for an Ubuntu host you have to edit /etc/network/interfaces file and :
auto lo iface lo inet loopback auto br0 iface br0 inet static address 10.1.1.7 netmask 255.255.255.0 gateway 10.1.1.1 bridge_ports eth0 bridge_stp on bridge_maxwait 0 bridge_fd 0
This will create a new bridge, br0, connected to the host interface eth0 and assign the
IMPORTANT: be aware that you are modifying the network configuration of your host interfaces and in case of problem you will connectivity to the host. This modifications should be done from the host console to avoid problems.
- Define a VNX <net> using that bridge:
<net name="Net0" mode="virtual_bridge"/>
- Configure VM interface on that net:
<vm name="vm1" type="libvirt" subtype="kvm" os="linux"> ...
<if id="1" net="net0"> <ipv4>10.1.1.40/24</ipv4> </if>
