Any specific reason why the GUI limits a VM to 512GB of ram? I need to use far more than 512GB in a VM, is there anyway this can get added to proxmox GUI. It looks like KVM can support upto 2TB of ram, I am able to manually change this within the vm.conf. It would be great to go above 512GB within the GUI.

I see in redhat link that maximum kvm ram can be 4TB or "Supports the maximum supported memory in the host, all of which may be allocated to the virtualized guest. 32-bit guests with Physical Address Extension (PAE) support will only be able to access 64 GB. This is a virtual hardware limitation."

In a scenario that my server has 8TB available RAM can i boot a 7TB kvm using proxmox(3 or 4)?

You have a server with 8 TB ram? Can you give details specs from this monster?
 
The history shows that the software capabilities are always in sync or ahead of the available hardware, so nothing to worry here.
 
Sorry to grab this old thread but the limit in the GUI is still there, can it please be removed? Thank you!
