尝试创建自己的 profle
|

mkdir /etc/tuned/virt-guest-alternative |
|

cat /etc/tuned/virt-guest-alternative/tuned.conf [main] include=virtual-guest [sysctl] vm.swappiness=10 [disk] devices=!vda readahead=4096 |
解释一下：
include 表明是继承virtual-guest的模版
剩下的常用模块为： cpu,disk,mount,net,vm,sysctl
我们还可以调用script模块：

[script] script=script.sh |
常用的函数可以通过如下命令查找：
