Virtualbox

Running on Grsec kernel

If someone out there should face the same problems as I did here are the Grsecurity features I had to disable to get VirtualBox running correctly:

  • grsecurity -> address space protection -> hide kernel symbols
  • grsecurity -> filesystem protections -> proc restrictions
  • pax -> non-executable pages -> enforce non-executable kernel pages
  • pax -> miscellaneous hardening features -> prevent invalid userland pointer dereferences

PXE Boot

  • Needs extenstions
  • On older versions only via bridged network support
