Changing EPT Level to 4?
Hi all

I am experimenting with Xen and I tried to change the EPT level from 3 to 4.
so in xen/include/asm-x86/hvm/vmx/vmcs.h I changed the value of ept_wl from
3 to 4.

Unfortunately Windows 7 can no longer boot with the change.

Is this expected?
What could be the problem?
Is there a workaround for this?

I would be willing to invest some time coding a fix for this, without
pointers or hints though it might take a lot longer though...

Thanks in advance and kind regards,
