Can xen server be configured to address more than 4Gb RAM. Since its based on a 32 bit kernel,is it possible to address more than 4GB ram.I have heard about PAE can it solve this?
Will changing the default 750M to more than 4Gb results in any performance degradation?
The only reason i want to add more ram to host is to load a 5 GB VM to completely run on RAM,for maximum performance benefits,for some testing purpose.
Installed RAM is more than 64 GB,and a lot of unused RAM.
