esxi 5.5 打开二次虚拟化

# vi /etc/vmawe/config

vhv.enable = "TRUE"

后面的都可以采用修改增加如下配置实现，无需要安装vCenter server, Web client等操作。

virtualHW.version = "9"

guestOS = "vmkernel5"

monitor.virtual_mmu = "automatic"

monitor.virtual_exec = "automatic"

vhv.enable = "TRUE"

改完重新启动esxi。

验证：

egrep '(vmx|svm)' --color=always /proc/cpuinfo

[root@kvm1 ~]# egrep '(vmx|svm)' --color=always /proc/cpuinfo
