KVM 嵌套虚拟化

KVM for Intel-based Machines

$ cat /sys/module/kvm_intel/parameters/nested
N

$ sudo rmmod kvm-intel
$ sudo sh -c "echo 'options kvm-intel nested=y' >> /etc/modprobe.d/dist.conf"
$ sudo modprobe kvm-intel
$ cat /sys/module/kvm_intel/parameters/nested
Y

$ modinfo kvm_intel | grep nested
parm:           nested:bool

KVM for AMD-based Machines

$ cat /sys/module/kvm_amd/parameters/nested
0

$ sudo rmmod kvm-amd
$ sudo sh -c "echo 'options kvm-amd nested=1' >> /etc/modprobe.d/dist.conf"
$ sudo modprobe kvm-amd
$ cat /sys/module/kvm_amd/parameters/nested
1

$ modinfo kvm_amd | grep -i nested
parm:           nested:int

编辑虚拟主机CPU字段

<cpu mode='host-passthrough'>
</cpu>

完毕！
