KVM for Linux 2.6.16?

KVM for Linux 2.6.16?

[Fischer, Anna]

Hi, I am trying to compile the kvm-87 module for Linux 2.6.16. I thought that it has been back-ported to such an old kernel. However, I don't seem to be able to compile the module on my kernel. I get the following error:

Is KVM not supposed to work on 2.6.16?

May I ask for the reason you want to run KVM on such an old kernel and  
even compile it yourself? :-)

Hi Anna,

I'm afraid that I have some bad news for you. Usually KVM versions are
tailored to kernel versions contemporary with them. Version 87 is
supposed to need 2.6.26 kernels and newer, IIRC. So for your 2.6.16 you
should try some of the incipient KVM versions, and if you are lucky
enough, they might work.

Anyway, are you so tied to that specific kernel version?

Regards,
Cristi

So if I run an ancient Linux kernel, then I can only run with an ancient KVM version? I thought the code was kept backwards compatible to some extend?

It is, but nobody really tested it on such old systems I think.

The issue you're running into is in userland though and related to usb  
passthrough. So you should be able to get away with disabling HOST_USB  
in your config-host.mak file.

May I ask again why you need to have things running on 2.6.16?

That's incorrect.  We try to keep compatibility from 2.6.16 forward.  
Due to the huge test matrix we often have problems, but once we get 
automatic testing going this will improve.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

./configure --extra-cflags='-D__user=""'

Will fix this.  The usbdevice_fs.h in sles10 is broken.
