To install VMware Server, open a terminal (Applications > System Tools > Terminal) and become root:
su
Then go to the location where you saved the VMware Server .tar.gz file, e.g. /home/falko/Download (replace falko with your own username!):
cd /home/falko/Download
Unpack the VMware Server .tar.gz file and run the installer:
tar xvfz VMware-server-*.tar.gz
cd vmware-server-distrib
sudo ./vmware-install.pl
The installer will ask you a lot of questions. You can always accept the default values simply by hitting <ENTER>.
When it asks you:
In which directory do you want to keep your virtual machine files?
[/var/lib/vmware/Virtual Machines]
... you can either accept the default value or specify a location that has enough free space to store your virtual machines.
At the end of the installation, you will be asked to enter a serial number:
Please enter your 20-character serial number.
Type XXXXX-XXXXX-XXXXX-XXXXX or 'Enter' to cancel:
Fill in your serial number for VMware Server.
After the successful installation, you can delete the VMware Server download file and the installation directory:
cd /home/falko/Download
rm -f VMware-server*
rm -fr vmware-server-distrib/
You will now find VMware Server under Applications > System Tools > VMware Server Console:
When you start it, select Local host:
Afterwards, you can create virtual machines (or import your virtual Windows machine that you created with VMware Converter):
