That's easy as 2+2=4! ;-)
You have 16384M of RAM memory in your Dell....
In your grub's menu.lst file, setup up this:
xenhopt=dom0_mem=512M
Now you have 15872M for your domUs... Let's see:
Setup each domU with 992M of RAM (~1G) so, you got 992*16=15872.
Don't forget to disable ballon in you /etc/xen/xend-config.sxp!
(dom0-min-mem 0)
(enable-dom0-ballooning no)
Cheers!

Hi,
I have a Dell machine, duel core xeon, with 16GB RAM. We are planning to run
Xen on it. The storage can be increased as required. For every guest host
the memory that is going to be allocated is 1 GB. These guest hosts are
going to run web applications (apache/tomcat) for which 1 GB Ram should be
more than sufficient.
Can I create more than 16 guest hosts in my physical host? If the total
number of host with 1GB RAM each exceeds 16, does XEN have any feature to
mange the memory efficiently so that memory will be allocated to guest host
based on the load on guest hosts at a particular point of time?
Thanks,
SV
