VMware Inc. announced yesterday the release of VMware Server, a free new entry-level hosted virtualization product for Linux and Windows servers.

VMware Server, the successor to VMware GSX Server, enables users to quickly provision new server capacity by partitioning a physical server into multiple virtual machines, bringing the powerful benefits of virtualization to every server.

While not open-source, this entry-level virtualization server enables users to partition x86 and x86-64 Linux and Windows servers into multiple virtual machines (VMs). Server administrators can either roll their own servers or use such pre-built servers as IBM WSE (Workplace Services Express), MySQL, or Oracle 10G.

Jerimy Katz is a Fedora developer. In a post to the fedora-devel-list he said:

We'll adjust the final schedule sometime next week based on the progress of the rebuilding efforts.

The script is very simple I give it here:

If for some reason you need to see what's running on another user's desktop, when you're both behind the same firewall, VNC is a good solution. But there is a problem when each user is behind different firewalls and you need a secure connection. Rob Reilly demonstrates how to make this secure connection happen when each user is behind different firewalls using VNC while tunneling over SSH.
