Package: virtualbox Version: 5.1.4-dfsg-1 Severity: minor Tags: upstream Hi,
I am trying to do nested virtualization and wanted to use virtualbox as the "inner layer" of the nest. This is needed because I want to test software using test-kitchen, which does not have a KVM driver. Because test-kitchen is not in Debian, I decided to move the entire setup in a scratch VM that I can easily snapshot and scrap. There are a few bug reports in the upstream tracker that virtualbox does not support nested virtualization and probably never will. As the bug reports are not clear whether they are talking about virtualbox as inner or outer layer of the virtualization, I decided to try it anyway. Actually, I do not know whether the _inner_ layer of a nested virtualization does need to know that it is running virtualized in the first place. That being said, virtualbox used as the inner layer of nested virtualization hangs at "Starting virtual machine (2/2) 20%". Clicks on the window close button are ignored, but it is possible to kill off the VirtualBox process. Virtualbox should properly detect situations it will not run in and report this to not confuse people. It should also document more clearly that "does not support nested virtualization" even applies to the inner layer of a nest.
