1. The first step is to take note of the network adapter's physical hardware MAC address. This is the MAC address assigned to the hardware. Enter the following commands and take note of the MAC addresses displayed. They will be used later in the procedure
   [dialogic@localhost dialogic]# ifconfig |grep HWaddr 
   Example:

2. Enter the grep command below. This command will display what the VM network scripts ifcfg\-eth0 and ifcfg\-eth1 are giving the network adapters for a MAC address.
   [root@localhost dialogic]# grep HWADDR /etc/sysconfig/network\-scripts/ifcfg\-eth*
   Example:

3. If the two MAC addresses from step 1 (VM script MAC's) and step 2 (Hardware MAC's) are the same, skip the next few steps and proceed to the next section to install the EMS software. If the MAC addresses are not similar the MAC addresses in the ifcfg-eth0 and ifcfg-eth1 files in the /etc/sysconfig/network-scripts directory will need to be replaced with the Physical Hardware MAC addresses from step 1.

4. Become a root user.
   [dialogic@localhost ~]$ su
   Password: Dial0gic (Capital D, zero for o)
   [root@localhost dialogic]#

5. Using the vi editor or some other text editor, open the ifcfg-eth0 file and replace the MAC address in the HWADDR="  " line with the physical hardware MAC address displayed for eth0. This was displayed from step 1 above.

6. Using the vi editor or some other text editor, open the ifcfg-eth1 file and replace the MAC address in the HWADDR="  " line with the physical hardware MAC address displayed for eth1. This was displayed from step 1 above.

7. Once completed, the network services need to be restarted. See below.
   [root@localhost network\-scripts]# service network restart

8. Verify the process worked. Enter the ifconfig command again for each adapter and verify the static IP address of 192.168.1.100 is now assigned to eth0 and dhcp has given eth1 an IP address as well.
   [root@localhost network\-scripts]# ifconfig eth0
   Example:

 Update System Software as Required

The procedure above installs the Virtual Machine application. Within the Virtual Machine just installed is the latest released version of EMS Software. If a newer version than the released version is required, a software upgrade must be performed. Refer to the Software Upgrade - EMS System topic to upgrade both the EMS Software running on the VM and the System Software running on the IMG 2020 nodes.
