Xen indeed sees all the memory.
But the client domU does not.
On the database domU:
free -m
total used free shared buffers cached
Mem: 32764 3519 29245 0 11 100
-/+ buffers/cache: 3407 29357
Swap: 2047 4 2043
Is this the domUs fault or how can I fix this?
Greetings,
bert

So Xen sees all of the memory.

Dear all,
I installed a xen hypervisor on a server with 96 GB ram.
I chose 64Gb ram for one domU called database. However when the domU
starts
it only has 32GB memory available.
I thought the max was up to 1TB. Am I doing something wrong?
Operating system: debian amd64 squeeze.
Thank you for your time,
Bert
