From b87a2d79ce8c5eee3a2f945b8eb00d893104fd10 Mon Sep 17 00:00:00 2001 From: Andrew Jones Date: Fri, 27 Mar 2015 21:19:00 +0100 Subject: [PATCH 16/27] Add ARM support Currently only detects LKVM, QEMU/KVM, and Xen. Also only works if the guest is booted with DT (which is the only way that currently exists).
