From ad0ce642799c15e3e5783bfcad60450c3f5687e1 Mon Sep 17 00:00:00 2001 From: Pavel Dovgalyuk Date: Mon, 29 Mar 2021 11:06:03 +0300 Subject: [PATCH] qcow2: use external virtual timers Regular virtual timers are used to emulate timings related to vCPU and peripheral states. QCOW2 uses timers to clean the cache. These timers should have external flag. In the opposite case they affect the execution and it can't be recorded and replayed. This patch adds external flag to the timer for qcow2 cache clean.
