[Fedora-xen] Memory in xen kernel < physical memory

[Danny_Trinh at Dell.com]

I have a system with 4 CPUs and 8GB RAM. I noticed that:
- When I boot up the machine with hypervisor kernel (fc5t3), I saw less
than 4GB RAM (/proc/meminfo). 
- When I boot up the machine with up kernel (fc5t3), I saw 4GB RAM
(/proc/meminfo). 
- When I boot up the machine with smp kernel (fc5t3), I saw 8GB RAM
(/proc/meminfo). 

Is that supposed to be for fc5t3?

Thanks,
