In addition, in connection with the deal, Qumranet's talented team of professionals that develop, test and support Qumranet solutions, and its leaders of the open source community KVM project, will join Red Hat.

According wikipedia:

Kernel-based Virtual Machine (KVM) is a Linux kernel virtualization infrastructure. KVM currently supports native virtualization using Intel VT or AMD-V. A wide variety of guest operating systems work with KVM, including many flavours of Linux, BSD, Solaris, Windows, Haiku, ReactOS and AROS Research Operating System.

VMware Server (formerly GSX Server) is an entry-level server virtualization solution which is proprietary, freeware software. VMware released version 2.0 beta of Server on July 1, 2008. VMware Server offers virtualization benefits such as:

+ You can create, edit, and play virtual machines.
+ Install any guest operating system for testing purpose.
+ Improve security.
+ Reduce downtime.
+ Control guest oses and VMware server from browser itself.
+ Improve resource utilization i.e. resource virtualization etc.

It uses a client-server model, allowing remote access to virtual machines.

Download VMware Server 2.0 Release Candidate 1

Please note that to use this version, you will need to register for your free serial number(s).

How do I install vmware?

Once downloaded simply use rpm command to install VMware software under CentOS / RHEL 5.x:
# rpm -ivh VMware-server-2.0.0-101586.x86_64.rpm
Before running VMware Server for the first time, you need to configure it for your running kernel by invoking the following command:
# /usr/bin/vmware-config.pl

How do I access and control my guest operating systems?

Fire a webbrowser and type the following url:
https://your.server.com:8333/
OR
https://your.server.ip.address:8333/

(Fig.01: Vmware server web login)
Once logged in you can see all your virtual machines and you can start / stop VPS oses:

You need to install Firefox add-on called "VMware Remote Console Plugin", once installed you can install any os or view guest / vps oses console:

You can easily list all running Virtual machines from a Linux shell prompt without accessing GUI. This is useful to scripts or to get status for any VM.

vmrun is a command line application for controlling various VM operations. Type the following command:
vmrun -T server -h 'https://vmserver.example.com:8333/sdk' -u VMUSERName -p 'yourVMPassword' list
Where,
=> -T server : This is VMWARE server version 2.x

=> -h 'https://vmserver.example.com:8333/sdk' : VMWare server hostname. This can be local or remote server.

=> -u VMUSERName : VMWare server username (usually it is root)

=> -p 'yourVMPassword' : VMWare server password

=> list : List all running vms

List all running VMs

vmrun -T server -h 'https://server.nixcraft.in:8333/sdk' -u root -p 'myPassword' list
Sample output:

Total running VMs: 2
[DISK315k] Debian5/Debian5.vmx
[DISK315k] CentOS52_64/CentOS52_64.vmx

Listing a virtual machine with Workstation on a Windows host (open dos prompt and type the command):
vmrun -T ws list
OR
vmrun -T ws -gu guestUser -gp guestPassword list
