가상화로 구현된 VM 내에 가상화로 구성하는걸 nested virtualization이라고 합니다.

HOST

nested KVM 커널변수값 확인

root@ubuntu:~# cat /sys/module/kvm_amd/parameters/nested

KVM AMD 커널모듈 제거하고 리부팅 이후에도 nested 가상화가 지원될수 있게 커널모듈 추가

root@ubuntu:~# lsmod |grep kvm

kvm_amd 60026 0

kvm 455843 1 kvm_amd

root@ubuntu:~# rmmod kvm-amd

root@ubuntu:~# lsmod |grep kvm

kvm 455843 0

root@ubuntu:~# sh -c "echo 'options amd nested=1' >> /etc/modprobe.d/dist.conf"

root@ubuntu:~# modprobe kvm-amd

root@ubuntu:~# modinfo kvm_amd | grep -i nested

parm: nested:bool
