DKMS does not support multiple kernels -> fixed in 5.1 and later releases

Description
The way DKMS is used on Linux does not support multiple kernels on the same machine. This is true both through "/etc/init.d/vboxdrv setup" and "do_dkms install".
The problem is that do_dkms first uninstalls *all* instances of the kernel modules across all kernel versions. Then it only builds/installs the modules for the current kernel. If you reboot to a different kernel, vboxdrv is not there; if you use the existing scripts, the modules for the other kernel will be gone when you come back to it.

Still happening on version 5.0.24. Why doesn't virtualbox generate kernel modules for all installed kernels ?

This should work for 5.1 releases. The fix will not be back-ported to 5.0. 5.1 does not use DKMS at all, but it uses the same hooks to build the modules when a new kernel is installed.

Please reopen if still relevant with a recent VirtualBox release.
