>From 51782a44eecf5801e5100920e5965d8dfc46e4cc Mon Sep 17 00:00:00 2001 From: Zhou Yimin <zhouyimin(a)huawei.com&gt; Date: Thu, 2 Jan 2014 16:32:46 +0800 Subject: [PATCH] qemuStateInitialize: Create qemu log directory When an error occurred in qemuProcessStart before qemu log directory created, it will fail to create qemu log file in qemuProcessStop during qemuProcessStart's cleanup phase. So when I start a VM whose PCI device not exist, the last error will be overwrited as "failed to create logfile XXX: No such file or directory" not the real reason "Device XXX not found:could not access XXX: No such file or directory". I fix it as following.
