I am evaluating XEN to see if we might be able to use it in
place of Vmware ESX for our Linux guests.  (Obviously will not work for
our Windows servers….)
 
I booted the demo CD under Vmware ESX and it worked
fine.  Xen guests under Vmware….
 
From the specs, I see there is a 4GB limit.  Is that
limit per domain, for all guests, or for the entire server?  Right now our
vmware servers are dual CPU Xeons with 12-16GB of ram each, running about 15
guests.
 
Is there an estimate when the 64 bit version will be released,
and if it will support a mix of 32 and 64 bit, or will it all have to be 64
bit?  (I don’t have any 64-bit hardware yet, but…)
