with Oracle VM 2.2.1 + the latest xen version in the channel (xen-3.4.0-0.1.21) you can run 1TB RAM, 128 threads.

When Oracle released its Sun Fire X4800 a few weeks ago, its documentation described the high-end x86 enterprise system as providing up to 8 sockets of Intel Xeon Processor 7500 series CPUs, huge memory, hot-plug PCI-Express gen 2 IO options, including access to up to 8 x 1GbE and 8 x 10GbE NICs and compute scalability up to 64 cores (128 threads with Intel Hyperthreading enabled). Now with Oracle VM, Wim Coekaerts reports full utilization of all 64 cores can be had even without hyperthreading enabled.

"We just now released a hypervisor update on ULN to also enable all the threads," writes Coekaerts, who is senior vice president of Linux and Virtualization Engineering at Oracle. "So with Oracle VM 2.2.1 + the latest xen version in the channel (xen-3.4.0-0.1.21) you can run 1TB RAM, 128 threads."

Oracle VM 2.2.1 is primarily a bug fix from the 2.2.0 release. This platform provides a fully equipped environment for better leveraging the benefits of virtualization technology. Oracle VM enables the deployment of operating systems and application software within a supported virtualization environment. The components of Oracle VM are Oracle VM Manager and Oracle VM Server.
