or Fibre Channel based cluster of virtual nodes. The VI Center installed on both Windows and Linux. After installation, the administrator had to configure a "management network" for the purpose of communicating with nodes in the cluster. The VI Center used the management network to PXE boot any server that was connected and correctly configured (for PXE boot). The included LiveRecovery tool could configure high availability. Additionally, CPU or power-consumption load-balancing was configurable using the LiveCapacity or LivePower tools respectively. Additional features included disk and virtual machine cloning (snapshots), IPMI/ILO support, etc.

s and had the advantage of hardware advances for better performance. Virtual Iron, Inc claimed to have pioneered the implementation of ''native virtualization''. Virtual Iron discussed paravirtualization and ''native virtualization'' in its blog:

Virtual Iron has decided against paravirtualization in favor of "native virtualization." With hardware advances coming out of Intel and AMD, we see native virtualization capable of matching physical hardware performance without any of the complexity and engineering efforts involved in paravirtualizing an OS. From our discussions with a broad range of users, they simply do not want to roll out modified OSs unless the trade-off is heavily in their favor. This Faustian trade-off is no longer necessary.
