[Xen-users] DomU max 32GB memory

[Bert Sarens <Bert.Sarens@xxxxxxxx>]

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
