[Xen-users] 32bit vs 64bit memory usage question

["Jamie Burns" <fantasticjamieburns@xxxxxxxxxxx>]

Hello,

I recently installed a minimal 32bit version of Debian Etch, and then also 
installed Xen from Debian's package repository.
When Xen booted up, memory usage was just below 40MB (typical for such a 
debian install).
Then I decided to do the exact same install, but using the 64bit version of 
Debian Etch and Xen.
This time when Xen booted up, memory usage was just over 90MB - at least 
double that of the 32bit version.
Can anybody explain this to me? Why 64bit XEN would use double the memory?

If I try 32bit vs 64bit debian without using XEN, then memory use about 30MB 
with each - no doubling.
Jamie Burns.
