From: Andrew Jones Date: Fri, 27 Mar 2015 20:19:00 +0000 (+0100) Subject: Add ARM support X-Git-Tag: 1.15~2 X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=87d670b4c8b4e4e0cc314736562a9a6612d555ef;p=virt-what.git 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).
