Now after the discussion is over against hyper-v, we have a new one.
I think this time about red hat virtualization will be not so easy.
Anyone allthough is doing comparision ?
•Consolidation ratios of more than 400 virtual machines with enterprise workloads running on a single server.
That is equal to the vmmark benchmark for 4 socket server with nehalem ex.
Reliability, Availability, and Serviceability (RAS)
•RAS hardware-based hot add of CPUs and memory is enabled.
•When supported by machine check hardware, the system can recover from some previously fatal hardware errors with minimal disruption.
•Memory pages with errors can be declared as "poisoned", and will be avoided.

Page 20 Future expectations
Red Hat claims RHEL 6 is designed to provide a focus on rock-solid physical computing, along with true virtual and cloud activity support. To that end, RHEL 6 includes kernel improvements for resource management, “RAS” (reliability, availability, serviceability), and more power-saving features. The KVM hypervisor can support guest operating systems with up to 64 virtual CPUs, along with 256GB of virtual RAM and 64-bit guest operating system.
