VMware software provides a completely virtualized set of hardware to the guest operating system. Virtualization is a technique used to implement a certain kind of virtual machine environment: one that provides a complete simulation of the underlying hardware. The result is a system in which all software capable of execution on the raw hardware can be run in the virtual machine. In this way you are able to run several Operating Systems on a single computer.
Virtualization separates an operating system from the underlying platform resources. There are two freeware products from VMware: VMware Player and VMWare Server. They are both “hosted” applications, which runs within an existing Linux or Windows operating system.
- VMware Player is provided as freeware. It can run, but not create, virtual machines
- VMware Server is provided as freeware. It is possible to create virtual machines with it.
To log in to VMWare Server 2.0, users will have to access https://localhost:8333/ui/ or http://localhost:8222/ui/ for non-secure connection (the URL may takes the form of your computer name). This will open the VMware Infrastructure (VI) Web Access management interface, which is VMWare Server Console. VMWare Server 2.0 installed Tomcat as web server in the background.
VMWare Infrastructure Web Access (VMWare Server 2.0) uses user account of the operating system, i.e Windows XP, Windows Vista, Windows Server 2003, Windows Server 2008 and Linux distro. So to login to VMWare Server 2.0 Web Console, logon with an administrative account’s user name of Windows or Linux (Administrator or root) and the corresponding password. Note the password is a must. In Windows, most built-in Administrator account does not have password by default even after been enabled, and so a password must be assigned.
VMware ESXi is antoher free product from VMware. This is an “unhosted” application, which runs without an existing Linux or Windows operating system (OS-independent). VMware ESXi is built on the same proven technology as VMware ESX, so it’s powerful enough to run even the most resource intensive applications and trusted enough for critical deployments. VMware ESX and ESXi Comparison
VMware ESXi is delivering greater performance than VMware Server, just as VMware ESX does. VMware ESXi differentiates itself from VMware ESX, because the Service Console is removed, and replaced with a minimal BusyBox installation, thus reducing the memory footprint, and the ability to manage the system directly from the console.
