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 the external interface (eth0 in this example). For example, for an Ubuntu host you have to edit /etc/network/interfaces file and change it in the following way (adapt the addresses and masks values to your case):
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 IP address 10.1.1.7 previously assigned to eth0 to the new bridge.
IMPORTANT: be aware that you are modifying the network configuration of your host interfaces and, in case of problems, you will loose the connectivity to the host. This modifications should be done from the host console to avoid problems.
