Hi all,

I'm going to install Xen on a new 64bit capable machine with 16GB RAM and two 
quad-core Xeon.
The domU's are (for migration issues) all 32bit PAE PV.
My question is, should I install a 32bit PAE (which i prefer) or a 64bit Xen?
Are there any known performance issues running 32bit PAE PV's on a 64bit Xen?
It's really unlikely that the machine will be upgraded to more than 16GB.

And btw. does someone know if the 32bit PAE PV domU's memory limit is also at 
16GB or smaller (well, assuming more
physical RAM)?

Thanks for any suggestions in advance!

Greetings
