Thread-topic: [Xen-devel] Xen 64 but supported memory limit
User-agent: Microsoft-Entourage/12.19.0.090515
The current limit is theoretically 1TB, but that should be easily
increasible. I think the largest tested memory configuration is 256GB. Max
per VM I think may actually be limited only by available memory.
