kvm嵌套(kvm_intel,
kvm_amd)
CentOS6.5 x64默认不支持kvm虚拟机嵌套，CentOS 7内核升级为3.10默认就支持。以kvm_intel为例，amd
CPU也是调相同参数。

修改kvm_intel内核模块参数nested N ==>Y

[root@test ~]# cat

[root@test ~]# echo ‘options kvm-intel nested=1’
>>/etc/modprobe.d/kvm_nested.conf
[root@test ~]# modprobe -r kvm-intel

针对要嵌套的虚拟机，在控制台将物理CPU的属性copy给该虚拟机，按钮“Copy host CPU
configuration”，以支持虚拟机嵌套。

VMware ESXi
5.0
VMware ESXi 5.0 默认情况下不支持嵌套虚拟，需要修改配置文件/etc/vmware/config，添加如下行
vhv.allow =
“TRUE”后重启ESXi，并将虚拟机类型调整为VMware ESXi5.x

VMware
Fusion8.0

Mac Pro通过VMware Fusion跑CentOS 7,再在CentOS 7里跑KVM

VMware
Workstation

自定义安装虚拟机设置完成后，虚拟修改foo.vmx这个配置文件件，Kernel
panic – not syncing: Attempted to kill init!
CPU支持VT及电源管理  apic.xapic.enable
= FALSE
SAS硬盘支持 scsi0.virtualDev = “Isisas1068”

修改完成后也要重新启动VMware Workstation
