This how-to summarizes how to create a new Ubuntu or CentOS virtual machine in the labs. To follow these steps, you need sudo/root access on Dns1 and the Dom0 that you wish to run this VM on.


The new virtual machine will be based off of one of the following generic VMs:

  • Choose whether the new VM needs to be on the server room network. Note: For security reasons, most VMs should not be on the server room network.

  • Choose whether the new VM needs to be on the internal network. Note: Most VMs don't need to be on the internal network.

Post Creation

Receive Email

The initial user should receive an email in roughly 5-10 minutes with details about their VM and their initial password to log in. If an error occurs, the initial user and several other members of the labs will receive a failure email indicating what part of the process failed.


The email should look similar to the following:

Update VM

It is recommended that you update your new VM after it is successfully created. You will have to restart your VM to apply kernel updates.

  • On Ubuntu 
apt-get update && apt-get upgrade
  • On CentOS 
yum clean all && yum update

Extra Packages

If you need web services, you can install them using the following:

  • On Ubuntu 
apt-get install apache2 php5 libapache2-mod-php5 mysql-server mysql-client php5-mysql php5-suhosin
  • On CentOS 
yum install httpd php php-mysql mysql mysql-server

Newer Distribution

If you need to update Ubuntu to the latest distribution, update apt 

apt-get update

and then install the package update-manager-core. 

apt-get install update-manager-core

Next, edit the file /etc/update-manager/release-upgrades to change Prompt=lts to Prompt=normal

Lastly, run 

do-release-upgrade

to start the distribution upgrade.

Conclusion

The virtual machine should now be up and running. Be sure to add it to the List of VMs.
