Hi @naY9yjoS6ZqhOd35sIFH

nested virtualization support is ongoing work and is currently not supported by the KVM-Backend for VirtualBox.

tpressure commented 2 months ago

You can try the following test branch for nested VMX (Intel). Note that SVM (AMD) is not supported right now.

https://github.com/tpressure/virtualbox-kvm/tree/nested_vmx_dev

To enable nested virtualization, you have to run VBoxManage modifyvm <vm_name> --nested-hw-virt on

Nested virtualization for Intel systems is now officially supported with the latest release: https://github.com/cyberus-technology/virtualbox-kvm/releases/tag/dev-20240502
