10.13. Enabling Nested Virtualization in Virtual Machines¶

Virtuozzo supports nested Intel VT-x virtualization in virtual machines.

To enable nested virtualization, do the following:

1. Stop all running or paused virtual machines on the node.

2. Unload the kvm-intel module from the kernel:

   # rmmod kvm_intel
   

3. Add the line options kvm-intel nested=y to the dist.conf file:

   # echo 'options kvm-intel nested=y' >> /etc/modprobe.d/dist.conf
   

4. Load the kvm-intel module:

   # modprobe kvm_intel
   

5. Enable nested virtualization in the desired virtual machine:

   # prlctl set MyVM --nested-virt on
