This a problem that gets reported repeatedly. I have a fix uploading to jaunty-proposed, in conjunction with a much higher SRU.

The kvm-source package is a dkms build of the kvm module. In order to build this, you *must* have the kernel headers installed for any kernel that you want to build kvm and boot.

Currently, we're depending on "linux-headers-server | linux-headers-generic | linux-headers".

This isn't good enough, though, as the user might have linux-headers and linux-headers-generic installed, but is running the linux-server kernel. In which, the dkms build fails, and reports the following helpful, informative message:

*************************************************

ERROR: Missing kernel headers.

You appear to have at least some kernel headers

installed, but you do not have the necessary

headers to build kvm-source against this kernel.

You might try installing the meta package:

 $ sudo apt-get install linux-headers-server

or specifically

 $ sudo apt-get install linux-headers-2.6.28-13-server

to obtain the necessary build dependencies.

*************************************************

This message tells users exactly how to solve the problem, however we still get bug reports by the truckload.

Thus, I'm proposing that we depend on all of "linux-headers-server, linux-headers-generic, linux-headers". This will involve installing extra headers on some systems. However, this is contained to users installing kvm-source, and will help avoid a lot of headaches.

Proposing for SRU, in conjunction with Bug #359447 and Bug #382077.

I think this is because apport suggests to report a bug when the
installation fails. It doesn't know about the helpful message.

[Dustin Kirkland  (kirkland)]

Good point. Thanks. Should be fixed in the upload proposed.

No, it's because the package fails to install. This should be avoided at all costs, the message should rather say how to fix the problem (install missing packages) and then manually start the build process. Or, already fail in the preinst, so that you don't end up with unconfigured packages in your system. However, I'm fine with adding all the -headers dependencies.

[Martin Pitt (pitti)]

Accepted kvm into jaunty-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!

[Dustin Kirkland  (kirkland)]

To verify this, you will need a rather trim system, without kvm, build-essential, dkms, or much along the lines of kernel headers. Enable -proposed and 'apt-get install kvm-source'. That should pull in a stack of build dependencies and headers, and the kvm module should then build, using dkms.

I should be able to verify this fix with a fresh server install next
week.

[Kenyon Ralph (kralph)]

I just installed kvm-source 1:84+dfsg-0ubuntu15 on a latest karmic server install. It installed cleanly.

[Kenyon Ralph (kralph)]

Just installed kvm-source 1:84+dfsg-0ubuntu12.3 from jaunty-proposed on a fresh jaunty server install with all updates. Installed cleanly.
