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?

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?
