Anyway, the first major thing was, I didn't want to install new machine from the scratch over and over. We have several Ubuntu servers and I just needed one install which I would reuse as a base for different servers.
The way to do it in ESXi is:
- Prepare one virtual machine for cloning. In my case it was to make a basic installation of Ubuntu server. Don't forget to install VMWare Tools, so you don't have to do it for each of your clones later.
- Then go to your datastare and make a directory for a new virtual machine. Go back to the directory of your Ubutu server installation from previous step. Copy all *.wmx and *.wmdk files over to your new directory.
- When done go to the new directory, right click on *.wmx file and choose "Add to Inventory". Finish the wizard.
- Start your new virtual machine.
- Go to console and edit /etc/hostname file to have the name you want your virtual machine to have.
- Go to console and edit /etc/hosts. Change hostname from the name of your cloned machine to the one form previous step.
- Go to console and edit /etc/udev/rules.d/70-persistent-net.rules You just need to comment first line and change eth1 to eth0 in the second line.
- In console edit /etc/network/interfaces and change IP of your machine.
