XenServer Configuration Maximums

I am trying to prepare config maximum for XenServer 5.6 . I will keep it updating till I test it .

For Virtual Machine

*A maximum of 8 VCPUs are supported by XenCenter.
†except for SLES 10 SP1 and RHEL 4.x, which support 3. RHEL 5.0/5.1/5.2 support 3, but can support 7 when the kernel is patched with the Citrix Tools for Virtual Machines. The same applies for Oracle and CentOS 5.0/5.1/5.2

Some 32-bit Windows operating systems can support more than 4 GB of RAM through the use of a special
mode - physical address extension (PAE) mode. Administrators wishing to reconfigure a VM with greater
4 than 4 GB of RAM must use the xe CLI, and not XenCenter, as the CLI does not impose any upper bounds for
memory-static-max

I will update this with XenServer config.
