Hello,
I just wanted to know
What is PAE/NX?
And VT-x/AMD-V I can't find anything about it and it seems quite strange to me
Actually, I simply installed VirtualBox and installed Linux Opensuse11 and I need to enable PAE/NX? and VT-x/AMD-V but I really don’t know what it actually does and it’s just out of curiosity.
Thank you in advance and I wish you a good day and/or good evening

I’m bringing up the subject again, but better late than never...
Intel VT and AMD-V are virtualization technologies. They were developed by Intel and AMD to create a semblance of paravirtualization with unmodified (and unmodifiable) systems like Windows, for example.
As a reminder, paravirtualization allows virtualized systems to communicate directly with the hypervisor without going through the driver layer that solutions like VMware Workstation or VirtualBox require.
The most well-known paravirtualizers are KVM and Xen (from Citrix).
For those in the know, Intel-VT and AMD-V simulate the installation of the hypervisor on a "ring -1" to make way for the guest OS on ring 0. Windows, which can only run on ring 0, sees nothing amiss.
...and the PAE/NX option allows for more than 4GB of RAM to be allocated to a 32-bit virtualized OS on a machine with more RAM.

Simple, clear, and precise.
