This is still the case in oneiric:

$ dpkg -x linux-image-3.0.0-11-virtual_3.0.0-11.18_amd64.deb .

As discussed in the ubuntu server team meeting
http://irclogs.ubuntu.com/2011/09/20/%23ubuntu-meeting.html#t16:02

There will be a -extras package that will contain the additoinal modules that were built.

If there is going to be a new package to handle this going forward, what is going to be the SRU process for older releases, specifically LTS?

As a first step it would help to have a bit more help in reasoning why those modules are needed. The virtual package was targeted to be used as a guest kernel in a vm. To keep the package footprint small some modules were not packaged. Now to get them added to the older releases it helps to have a real-world use case to make the argument.

Lucid (10.04) is even more a special case. Back then, the virtual packages are just module subsets of the generic-pae (i386) or server (amd64) packages. While later virtual became its own flavour which allowed us to use slightly tuned compile options.
So, as confusing as all of this is, in Lucid one can use generic-pae or server and get all modules, while later on there is a difference (though mainly whether xen drivers are built-in or modules).

Without the quota modules, a server cannot have data quotas per user on the filesystem. This effects all versions up to Oneiric. When a person uses any kind of quota restriction whether it's manual, or via an application such as Plesk or CPanel, it will not work since these modules are missing.

Yes, this can be worked around by downloading a different kernel and loading up the modules from that kernel, but it is just that, a workaround. The environment we are using Ubuntu in, has automated deployments that needs/uses the -virtual kernel. It would cause more overhead to use this workaround every time we deploy a new Ubuntu box.

This is a standard module that is needed no matter what kernel or server is in use, and should be considered as a bug that needs to be fixed.

For Lucid (10.04) this is actually already fixed for the kernel in updates at least:

dpkg --contents linux-image-2.6.32-33-virtual_2.6.32-33.72_i386.deb |grep quot
-rw-r--r-- root/root 4476 2011-07-30 02:37 ./lib/modules/2.6.32-33-generic-pae/kernel/net/netfilter/xt_quota.ko

-rw-r--r-- root/root 6952 2011-07-30 02:37 ./lib/modules/2.6.32-33-generic-pae/kernel/fs/quota/quota_v2.ko

Maverick (10.10) is not really worth fixing. But I'll queue up changes for Natty (11.04). As mentioned for Oneiric we will have an extra package with anything not added to the kernel package directly, so that should be resolved.

"Maverick (10.10) is not really worth fixing"

Why is that? There's still seven months to go.

I have this -exact- (quota) problem with a 10.10 Amazon EC2 instance (2.6.35-24-virtual i386/i686, I don't have the ami & aki to hand)

It seems it wouldn't be that difficult to roll quota* into the next kernel -virtual update for 10.10?

At present, I can't see what the valid workaround is. Apparently:

* -server doesn't have the right Xen bits for Amazon EC2
* -ec2 is the "old" Amazon EC2 kernel and we should be using -virtual from now on

This leaves me with -: roll our own (obviously more work and not future proofed) or do a complete in place upgrade to 11.04?

I would appreciate views on what the valid workaround is.

I can see how you might want to drop hardware specific drivers or obscure functionality but there seems to have been some pretty rampant pruning done for -virtual all around. It doesn't take much Googl'ing to find at least a couple of bug reports showing the dropping of nfs related stuff, modules relating to character sets that I would have thought were 'core' OS.

Mostly because of trying to minimize changes that are not critical for older releases that are not LTS or the current one. Ok and probably the assumption that with virtual deployments those things would move quicker to the current release. But no, the change is not really hard to make and if there is a real need and someone to do testing feedback, it could be done.

Thanks. When will this be available for testing, and/or fully released? Wondering if there is anything further I need to do.

Stay tuned here. There will be an announcement when a new kernel package that contains this change is uploaded into proposed for testing. Make sure to verify/comment whether that package has the modules missing. It should be in the next one but I cannot give an exact timeline.

This bug is awaiting verification that the kernel for Natty in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-natty' to 'verification-done-natty'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.
