#10487 obsolete VirtualBox upgrade should not fail, if the old kernel modules cannot be removed Harri
Description

Debian Linux host (Squeeze):

If VirtualBox is running, then the postinst script does not allow to complete the upgrade to a newer version. The new user space binaries are all put into place (AFAICS), but the new kernel modules are not built and the upgrade fails.

In an enterprise environment this means a lot of additional work for the IT folks, begging the users to stop their VirtualBox sessions before leaving. Highly painful. And the users don't want to be bothered by this, either.

It would be much smarter if the postinst script wouldn't fail about this. Since the old vbox* modules are already loaded in the kernel, the module files(!) can be overwritten without affecting the running VirtualBox sessions (similar to the user space binaries).

To be on the safe side the VirtualBox startup script could check the vbox* kernel modules on the next reboot and rebuild them, if they don't match the installed VirtualBox version. This check should be trivial.

#11818 duplicate running Virtualbox guest dies with warn_alloc_failed Harri
Description

Starting a guest on a Linux desktop machine failed with the attached kernel error messages. AFAICS this is not documented, so I wonder what it is trying to tell me?

The host is a Sandybridge i7 with 16 GByte RAM. There is plenty of RAM available (>8GByte, as reported by free -m).

#16286 fixed Kernel module does not compile with Linux 4.9 HarryE
Description

The kernel module is not compiling with Virtual Box 5.1.10 for Debian Jessie and Linux 4.9. I get the following compile error:

I included my kernel configuration.
