It's an architectural requirement to have LPAE if the virtualization extensions are present. Theoretically you could code the kernel so you could run it without LPAE enabled and still support KVM, but you would have to change all the page table manipulation code to use custom defines for these purposes. I don't see the point, and it's not something that's going to go in mainline. -Christoffer _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
