Hello all!
I have actual need to build a custom kernel.(Have to change Preemption model to 'server' and turn off Preempt the big kernel lock, ect) I have heard bits and pieces about these changing defaults in newer kernels but I haven't investigated that yet.
This of course is not a problem at all, made my needed changes to the source code and successfully build both the standard and the Xen kernel using the rpmbuild guide from this site found here: http://wiki.centos.org/HowTos/Custom_Kernel
Built: kernel-2.6.18-194.11.4.el5.1.x64.x86_64 kernel-xen-2.6.18-194.11.4.el5.1.x64.x86_64
The standard kernel works well, I haven''t messed around much with Xen yet (I get an "Error 13: Invalid or unsupported executable format") if I try to boot to the xen kernel - I have Xen installed correctly I believe:
[kend@test225: ~]# rpm -qa | grep xen xen-3.0.3-105.el5_5.5.x86_64 kernel-xen-devel-2.6.18-194.11.4.el5.1.x64.x86_64 xen-libs-3.0.3-105.el5_5.5.x86_64 xen-devel-3.0.3-105.el5_5.5.x86_64 kernel-xen-devel-2.6.18-194.11.4.el5.x86_64 xenwatch-0.5.3-3.el5.x86_64 kernel-xen-devel-2.6.18-8.el5.x86_64 kernel-xen-2.6.18-194.11.4.el5.x86_64 kernel-xen-2.6.18-194.11.4.el5.1.x64.x86_64
But I need to nail down this KVM issue as I would rather use full hardware for my virtualization. Problem I have is that I cannot find a source rpm package for kmod-kvm that will work with my kernel. There are instructions on the KVM site on how to build external module for older kernels, and I tried that, but to make a long story short, mt 2.6.18-194 kernel has no available source rpms that I can use for my custom kernel.
Can anyone point me to a source package for kmod-kvm that will work with my 2.6.18-194.11.4.el5 kernel base?? I have spent 2 full days digging through packages on the web and I cannot come up with anything. Thinking of just going with trying out Xen instead, but of course I have an dd issue there too.
Any help with either of these issues would be very much appreciated!
Sorry for the long post
