Installing VMWare Server 2.0 Beta on Ubuntu is really a no-brainer, except for two things:

• Ubuntu is by default installed with IPv6, and VMWare is incompatible with this and fails to function.
• Ubuntu has no root account enabled, so the default administrative user needs to be altered.

Following is an account of the installation on my Ubuntu Hardy Heron.

VMware Server is currently not compatible with Debian-style IPv6 (or IPv6 at all), so we must disable that first. To do this, edit /etc/modules.d/aliases, and change

alias net-pf-10 ipv6

to

alias net-pf-10 ipv6 off
alias net-pf-10 off
alias ipv6 off

Add the following line to /etc/modprobe.d/blacklist :

blacklist ipv6

The IP-related modules are tightly tied, so the best option to get these changes picked up, is by rebooting the system.

Install an internet superserver that VMWare understands (xinetd)

sudo apt-get install xinetd

VMWare server is going to compile kernel modules etc, so we need the followin aswell:

sudo apt-get install build-essential

Now, go fetch the tar.gz package of VMWare Server 2.0 Beta from http://vmware.com/beta/server/ and unpack the tar to a suitable location and start the installer:

# assuming the tarball is located in your home directory, and is named "appropriately"  
cd /tmp
tar zxvf ~/VMware-server-e.x.p-*.tar.gz
cd vmware-server-distrib
sudo ./vmware-install.pl

Answer the questions presented during the installation. The defaults should be safe in most cases. Personally, I choose to change the HTTP and HTTPS ports, using 8222 and 8333

VMWare Server insists on using root as the only user available by default, and as that user is disabled in Ubuntu, we need to change the default username. This is done in the file /etc/vmware/hostd/authorization.xml, bu changing the option ACEDataUser form root to your username

sudo vim /etc/vmware/hostd/authorization.xml 

Basically, restarting VMWare at this point should give you a working setup. To be safe, I opted on rebooting.
