Problem is still there with the latest kernel & virtualbox-4.1:
oem@oem-desktop:~$ sudo /etc/init.d/vboxdrv setup
[sudo] password for oem:
* Stopping VirtualBox kernel modules
[ OK ]
* Uninstalling old VirtualBox DKMS kernel modules
[ OK ]
* Removing old VirtualBox netadp kernel module
[ OK ]
* Removing old VirtualBox netflt kernel module
[ OK ]
* Removing old VirtualBox kernel module
[ OK ]
* Trying to register the VirtualBox kernel modules using DKMS
Error! Bad return status for module
build on kernel: 3.2.0-2-generic-pae (i686)
Consult /var/lib/dkms/vboxhost/4.1.6/build/make.log for more information.
* Failed, trying without DKMS
* Recompiling VirtualBox kernel modules
* Look at /var/log/vbox-install.log to find out what went wrong
Some kernel change related to iommu seems to break the Oracle package:
https://lkml.org/lkml/2011/6/22/106
/var/lib/dkms/vboxhost/4.1.6/build/vboxpci/linux/VBoxPci-linux.c have
some #include entries:
#include <linux/intel-iommu.h>
#if LINUX_VERSION_CODE < KERNEL_VERSION(3, 1, 0)
# include <asm/amd_iommu.h>
#else
# include <linux/amd-iommu.h>
we can see they are not found apparently:
oem@oem-desktop:~$ sudo find / -name amd-iommu.h
[sudo] password for oem:
/usr/src/linux-headers-3.2.0-2/include/linux/amd-iommu.h
/usr/src/linux-headers-3.2.0-2-generic/include/linux/amd-iommu.h
/usr/src/linux-headers-3.2.0-3-generic-pae/include/linux/amd-iommu.h
/usr/src/linux-headers-3.2.0-3/include/linux/amd-iommu.h
/usr/src/linux-headers-3.2.0-2-generic-pae/include/linux/amd-iommu.h
so its amd-iommu.h (with hypen, not underscore) & kernels are 3.2 of
course.
