linux-image-virtual (i386): many modules missing on Karmic

Bug Description

linux-image-virtual doesn't contain module binfmt_misc, whereas linux-image-generic does.

I am using virtual machine to have "boxed" environment for cross-compilation with scratchbox, which needs binfmt_misc to execute ARM binaries.

Currently, I need to use the "generic" flavour of the Linux kernel in the virtual machine.

$ dpkg -l "*virtual*"
ii linux-image-2.6.31-14-virtual 2.6.31-14.47 Linux kernel image for version 2.6.31 on x86/x86_64
ii linux-image-virtual 2.6.31.14.27 Linux kernel image for virtual machines
ii linux-virtual 2.6.31.14.27 Complete Linux kernel for virtual machines

$ uname -a
Linux vm-xubuntu 2.6.31-14-generic-pae #47-Ubuntu SMP Thu Oct 15 03:26:34 UTC 2009 i686 GNU/Linux

$ cat /proc/version_signature
Ubuntu 2.6.31-14.47-generic-pae

I just checked and found out that the module is missing only in the deb for i386, but is there in the package for AMD64.

I compared the list of files for amd64 and i386 of the virtual linux flavours 2.6.31-14.47. The difference is huge. It seems that the compete kernel/fs is missing in the i386 version of the deb.

Or am I misreading something?

When I upgraded my virtual host to karmic, autofs stopped working because of this bug, which meant that the host didn't work at all. The diff in comment #2 also shows nfs missing, which probably means that A LOT of virtual hosts will break due to this bug. This is a very serious bug.

A workaround is to install linux-image-2.6.31-14-generic and use that kernel instead.

I confirm the bug which is very serious: Upgrading to Karmic disables LOTS of functionalities that were working in Jaunty. For me:

sudo modprobe smbfs
FATAL: Module smbfs not found.

Workaround by installing the generic kernel works perfectly.

I got a bug fix for that in the pipe. The packages in my Karmic PPA are including that. It would be good if someone could check those and give me feedback on it. Thanks. (https://launchpad.net/~stefan-bader-canonical/+archive/karmic/+packages)

I installed linux-image-2.6.31-14-virtual (i386) from your ppa and it boots correctly and the autofs4 and nfs modules load and seem to work.

Accepted linux into karmic-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I just installed version 2.6.31-15 of 32-bit linux-image-virtual and the missing kernel modules are there. Thanks for fixing this problem.

The modules nfs and autofs4 that were missing from 2.6.31-14 are working in linux-image-2.6.31-15-virtual 2.6.31-15.49. Thank you.

This bug was fixed in the package linux - 2.6.32-3.3
