VMware Server and 64 bit guests

Although VMware Server 2 should be able to support 64 bit guests it needs to be installed ontop of  a 64 bit OS on a 64 bit CPU  which has VT support.

For example a Dell PowerEdge 1800 with Intel(R) Xeon(TM) CPU 3.00GHz can only run 32 bit guests ! and if you try to install or run a 64 bit guest you’ll get the error message:

Message on www: This host does not support VT.
You have configured this virtual machine to use a 64-bit guest operating system.
However, this host is not capable of running 64-bit virtual machines
or this virtual machine has 64-bit support disabled.
For more detailed information, see http://vmware.com/info?id=152

HOWTO Disable VMware Server 2 autostart & mgmt

By default the VMware Server 2 file /etc/rc.d/init.d/vmware starts and stops all three vmware services (core, mgmt, autostart) so if you never want autostart to run you can comment out all the “service_vmware_autostart” lines !

red hat 5.x 64bit & vmware server 1.x

red hat enterprise linux 5.x 64bit with vmware server 1.x does not work out of the box ! since when you try and install it you may get the following error(s):

The correct version of one or more libraries needed to run VMware Server may be missing.
libX11.so.6 => not found
libXtst.so.6 => not found
libXext.so.6 => not found
libXt.so.6 => not found
libICE.so.6 => not found
libSM.so.6 => not found
libXrender.so.1 => not found
This program cannot tell for sure, but you may need to upgrade libc5 to glibc before you can run VMware Server.

and then when you try and enter your serial number you may get:

Please enter your 20-character serial number.

Type XXXXX-XXXXX-XXXXX-XXXXX or ‘Enter’ to cancel:


error while loading shared libraries:


cannot open shared object file:

No such file or directory

The serial number XXXXX-XXXXX-XXXXX-XXXXX is invalid.

this is because vmware server has been compiled against the 32bit X libraries which dont exist by default on a centos 64bit, oracle 64bit or red hat 64bit linux system so you’ll need to install them manually using:

# yum install libX libXtst libICE libSM

then re-run

# vmware-config.pl

VMware Server 1.x is alive and well

VMware Server 1.x is alive and well and still works fine with a CentOS/OEL/RHEL 5.x host and CentOS/OEL/RHEL 5.x guests

If you’ve ever struggled with VMware Server 2.x security configuration you should  find VMware Server 1.x security model much easier !
