From ec081984f4ae7017e30f58599be54271e1b66d29 Mon Sep 17 00:00:00 2001 From: Zhang Chen Date: Fri, 16 Oct 2020 13:52:06 +0800 Subject: [PATCH] net/colo-compare.c: Change the timer clock type MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The virtual clock only runs during the emulation. It stops when the virtual machine is stopped. The host clock should be used for device models that emulate accurate real time sources. It will continue to run when the virtual machine is suspended. COLO need to know the host time here.
