Hi Akemi, Thanks for the reply.

Do you mean no src.rpm of your custom kernel? If so, rpmbuild -bs will build >it.

The only source rpm I can find is from the CentOS Extras. FIlename makes it appear that you need the 2.6.18-8.1.8 kernel from CentOS Extras: kvm-kmod-36-1.2.6.18_8.1.8.el5.src.rpm

If I try to rebuild that with: rpmbuild --rebuild --target=x86_64 kvm-kmod-36-1.2.6.18_8.1.8.el5.src.rpm

I get error that I need the 2.6.18-8 kernel-devel package, if I install that it will build but it results in a kernel module built for the 2.6.18-8 series but I need for my 2.6.18-194 series.

So on your advice I jumped into my SPECS dir and tried: rpmbuild -bs --target=x86_64 kvm-kmod.spec

and it gave me: Wrote: ~/kend/rpmbuild/SRPMS/kvm-kmod-36-1.2.6.18_194.11.4.el5.1.x64.src.rpm

I guess it all comes down to experience. Being not to familiar with rpmbuild I did not know you could do that. Thanks for the tip!

kmod-kvm is built from kvm and it is kernel version independent, kABI-tracking. This means that, if your custom kernel is kABI compatible with the distro kernel, the kvm module will continue to work.

I wish that was better documented. So as long as I have kABI checking enabled when I build my custom I should be golden? I apparently did not fully understand kABI either than. I did have some trouble with kABI at first and disabling it solved the issue, not sure if it's still disabled, but I will check. Thanks for the info!

I wont call this thread solved until I get the chance to try these two options out and see where I get. Sounds like sticking with using kABI is my best bet either way if case I run into this again in the future with other things. Getting into the visualization world for the first time so I have a learning curve to clime here. Thank you for the tips, I will do some testing then post the results.
