From 939dd2d350b966016f2a1fa126242c094e71cd82 Mon Sep 17 00:00:00 2001 From: Roman Kagan Date: Mon, 27 Nov 2017 16:05:18 +0300 Subject: vmgenid: use UUID property type MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Switch vmgenid device to use the UUID property type introduced in the previous patch for its 'guid' property. One semantic change it introduces is that post-realize modification of 'guid' via HMP or QMP will now be rejected with an error; however, according to docs/specs/vmgenid.txt this is actually desirable.
