[Pkg-virtualbox-devel] Possible bug with vboxsf module

[Parke]

Hi Virtualbox Team,

Today I may have discovered a bug that caused wrong version of the
vboxsf module to be installed on a Debian guest.

Here is what I think happened:

1) I installed a 32-bit Debian guest on a 64-bit Ubuntu 14.04 host.  I
probably used debian-7.0.0-i386-netinst.iso to do the installation,
but it was a while ago.

2) The guest installed using kernel 3.2.0-4-486

3) However, the guest vboxsf module installed in:
/lib/modules/3.2.0-4-686-pae/updates/dkms/vboxsf.ko

To work around the problem, I did apt-get install linux-image-686-pae.
I also enabled PAE/NX for the guest in VirtualBox.  Then I booted the
686-pae kernel.

Another possible workaround:  It appears that I have been able to
build the 486 version of the module by running apt-get install
linux-headers-486.

I have not tried to reproduce the problem by creating a fresh Debian
guest, but I would be willing to try to reproduce it if the Debian
Virtualbox Team is interested in fixing it.

Thanks!
