openxVM

xVM is the intersection of virtualization and management. OpenxVM is a community hub for a number of related open source projects that together create the next generation of data center infrastructure.

Apparently VMware Server 2 beta lets you force VMs into BIOS setup mode :

- go to you VM with the VI client
- stop the machine
- then Options tab
- then "Boot options"
- check "Force BIOS setup".

Veeam FastSCP (Fast & Secure Copy) facilitates the deployment and simplifies backup of virtual machines(VMs) on VMware ESX server.

Veeam FastSCP is a fast, secure and easy-to-use tool to perform file management in ESX environment. FastSCP allows a user to copy files from ESX to Windows, Windows to ESX or ESX to ESX. This is the most natural way to deliver an ISO file to ESX Server, make a backup copy of an existing virtual machine (VM) or copy VMs and templates between ESX servers.

FastSCP ensures security by using a one-time password feature and works over 6 times faster than SCP.
