Except for your host machine, all the Virtual Machines in this course will have '''static network configuration''' (as opposed to Automatic or DHCP).Sometimes, you will be required to debug networking problems quickly by changing the network configuration of your VMs. 

<li value="7">Edit the '''ifcfg-''interfacename''''' file for each of your VMs to use a static IP address (refer to previous OPS235 lab on networking: [ [http://zenit.senecac.on.ca/wiki/index.php/OPS235_Lab_6_-_CentOS7#Part_4:_Configuring_VM_Network_Setup_via_Command_Line_.28centos3.29 Network Config - CLI] ].<br> You should be configuring the BOOTPROTO ('''static ''' instead of dhcp), IPADDR, NETMASK, GATEWAY, and DNS1 for this file. Note the following information for this setup:<ul><li>You will be using your last 2 digits in your student number for the third octet in your IPADDR. Your vm1 should use the first available address in the subnet, vm2 the second, and vm3 the third. Make certain that the '''IPADDR does not interfere with the GATEWAY or DNS!'''</li><li>Don't forget to set the default gateway and DNS server for your VMs. You can use your host's IP address as a DNS server (''libvirt'' will proxy the requests to the real DNS server).</li><li> You can refer to your previous lab to obtain information for setup of these options: [ [http://zenit.senecac.on.ca/wiki/index.php/OPS335_Installation_Lab#Configuring_a_VM_host Configuring a VM Host] ]<br><br></li></ul><li>Make note of the files used and entries required and note them in your lab log-book.</li><li>Save your editing session, and then restart each VM and run the following command to ensure they still have the network configuration you set:</li></ol>
