Gourd CentOS 6 Migration

Gourd is currently running RHEL 5.11. The goal is to upgrade Gourd to CentOS 6.

The steps to take is to first install a gourd clone on Tomato. Virtualize a Roentgen clone on Tomato. Once everything is all setup we can simply swap the hard drive on Gourd with Tomato's harddrive.

Logs

CentOS 6.6 is installed on Tomato. It has gourd's username, no users, no internet-connection, and the expected root password. It is connected to Pumpkin's unused interface and set with a temporary address 172.16.0.3. The interface for Pumpkin is set with a temporary address of 172.16.0.2. For internet access I plugged Tomato into my personal laptop and bridged my wifi with my ethernet connection. Tomato was updated. A list of all packages on Gourd was generated and a yum install was executed for all of those packages. Unavailable packages were logged.

It was found that Tomato's CPU did not have virtualization support. As an alternative we tried installation on one of the computer clusters but it seems the power supplies died whenever we tried to move them around. This resulted in two dead power supplies with unknown cause of death. Creating Tomato on a VM would work, but I didn't want to deal with any problems that could arise with nested virtual systems. In the end we took Tomato's hard drive and installed Gourd on that.
