To learn more about the current state of support, search the qubes-devel and qubes-users mailing lists for terms such as VirtualBox, KVM and/or nested virtualization. Running VirtualBox, KVM or Qubes inside Qubes is difficult and is not offically supported by the Qubes developers this is unrelated to Kicksecure ™. This demonstrates that extra code is required for this functionality and that also implies a greater attack surface.īy mixing virtualizers - for example by running VirtualBox inside the VMware virtualizer - the attack surface is increased because the virtualizer code of both products is involved which increases risk of a "break out". As one of the best free emulators in the. For example while the VirtualBox virtualizer has existed for years, the ability to run VirtualBox inside VirtualBox using Intel CPUs was only offered as a feature in v6.1 released in 2020. Methods to fix the loading failure when facing the situation that the virtual box stops at 94, 50, 30, etc. Nested virtualization is not automatically offered as a feature and this is also true for various third party virtualizers. Nested virtualization is not a simple by-product of developing a virtualizer. Not all hypervisors and operating systems support nested virtualization. Further nested virtualization would result in a level 2 (L2) hypervisor inside the nested VM, then a level 3 (元) hypervisor within that nested VM, and so forth. The hypervisor running the main virtual machine is considered a level 0, or LO hypervisor, and the initial hypervisor running inside the virtual machine is referred to as a level 1 or L1 hypervisor. With nested virtualization, you're effectively nesting a hypervisor within a hypervisor. In other words, it's the ability to run a hypervisor inside of a virtual machine (VM), which itself runs on a hypervisor. Nested virtualization refers to virtualization that runs inside an already virtualized environment. This configuration is known as nested virtualization: It is possible to run virtual machines (VMs) inside other VMs. 6 Running Kicksecure ™ in a Nested Virtual Machine.
