KVM磁盘性能优化

磁盘性能是虚拟技术中的一个瓶颈,虚拟机由于经过封装以后,磁盘有所下降,尤其要对磁盘性能进行优化。

优化要点:

1、在母机(host)上,设置磁盘调度器为 deadline,有两种方法

– 在启动的时候,加入参数(需要重新启动):
elevator=deadline

– 或者实时调整参数(不需要重新启动,但是下次启动时丢失):
for f in /sys/block/sd*/queue/scheduler; do echo “deadline” > $f; done

2、使用 virtio,一定注意,否则导致磁盘性能严重下降

3、在虚拟机(VM)上,设置磁盘调度器为 noop,有两种方法

– 在启动的时候,加入参数(需要重新启动):
elevator=noop

– 或者实时调整参数(不需要重新启动,但是下次启动时丢失):
for f in /sys/block/sd*/queue/scheduler; do echo “noop” > $f; done

4、尽量使用 LVM 作为虚拟机的磁盘,qcow2会带来额外的负担,从而导致IO性能下降

 5、注意虚拟机内的 virtio驱动程序一定是最新的,特别是windows虚拟机
