[Xen-devel] Hypervisor Memory Limitations on 64-bit Architecture?

[Joshua West <jwest@xxxxxxxxxxxx>]

Hey all,

I'm wondering if anybody could shed some light on this subject.  Are
there limitations as to how much RAM a 64-bit Hypervisor will
recognize/support under the Xen 3.1.x or 3.2.x series (or the upcoming
3.3.x if anything has changed)?

>From what I recall, a 32-bit Xen Hypervisor will recognize up to 16GB of
RAM and a 64-bit Xen Hypervisor will recognize up to 32GB -- but I'm not
certain on if 32GB is in fact the upper limit for 64-bit Xen.

Thanks.
