Install VMWare on Ubuntu
At first install those package:
apt-get install linux-headers-`uname -r` libx11-6 libx11-dev xspecs libxtst6 psmisc build-essential
Then download binaries on http://www.vmware.com/download/server/ (server & mui tgz source).
During the download, get a license number (http://register.vmware.com/content/registration.html) it’s totally free!
If you use kernel 2.6.27 please launch:
wget -c http://www.insecure.ws/warehouse/vmware-update-2.6.27-5.5.7-2.tar.gz
Then launch ./vmware-install.pl on each directory (update&mui or install&mui).
At the end of the mui installation you will get a starting failed message, to correct this bug please change in /etc/init.d/httpd.vmware file:
start)
vmware_exec "Starting httpd.vmware:" vmware_start_httpd
;;
stop)
vmware_exec "Shutting down http.vmware: " vmware_stop_httpd
;;
by
start)
if [ ! -d /var/run/vmware/httpd ]

echo "Directory: var/run/vmware/httpd Not found. Creating it."
mkdir /var/run/vmware/httpd
echo "Setting user and group ownership to: User: www-data, Group: nogroup"
chown www-data:nogroup /var/run/vmware/httpd
echo "Setting directory permissions to: RWX------ (700)"
chmod 700 /var/run/vmware/httpd
fi
echo "Starting httpd.vmware:"
vmware_start_httpd
