Red Hat Enterprise Linux 6 as a virtual guest, upholding Red Hat’s

commitment to refining the overall virtualization experience.

Virtualization updates in Red Hat Enterprise Linux 6.6 Beta include

support for a host to feed randomness to a virtual machine, increasing

security for cryptographic applications, multi-queue performance
