Originally virtualization was slow on grsec/pax with either uderef or |
14 |
kernexec enabled. Pipacs overcame this limitation in 3.5.4-r1 and |
15 |
overcame a memory commit issue kvm was having in 3.5.4-r2. He overcame |
16 |
it using nested page tables on newer CPUs, which means older CPUs will |
17 |
likely still be slow. |
