The answer is 42, er no 64
The newly announced UltraSPARC-T2 processor is choc-full of thread goodness, 64 of them in all. So what to do with this bounty? Run Logical Domains on them of course!
Here is screenshot displaying in xterms the primary domain console (lightgreen) and 63 guest domain consoles (orange) of 64 domains running on a single UltraSPARC-T2 processor.
There is also a flash demo made by Ash showing a single UltraSPARC-T2 starting and booting Solaris on 64 logical domains.
That is very cool, I assume you have one processor dedicated to each LDOM, correct? and how is your memory allocated for that many LDOM's?

Yes, each LDOM had one virtual processor (i.e. hardware thread) dedicated to it. The system had 32GB of memory installed. 4GB was allocated to the primary domain and each of the other domains was allocated 400MB.
