There was a problem hiding this comment.
we need to clarify it's the axvisor itself uses 4-level page table or it's the guest kernel that uses 4 level pt.
Maybe "4-level-ept" is better?
Btw, can we make sure that the hardware does not support 4-level pet?

"4-level-ept" is modified.
yes, The Cortex-A55 core supports a 40-bit physical address range, which allows 1TB of physical memory to be addressed. which is mentioned in Cortex-A55 TRM A5.1.1 Main functions. If the page size is 4KB, 4-level-ept required at least 48-bit.
