So that's what is for. I was wondering when I inspected contents of your 
rpm's. "Every day in every way I progress more and more". I must 
apologize for making the confusion, I will try to restrain my self from 
giving further advices, and will also make sure I post just in this 
mailing list and not to your personal mail.

I do have 2 questions:

1. What happens if I manually install OLDER kernel with rpm -ivh 
kernel-..... --force? will kmod create necessary symlinks?

2. If rpm is build with non-existing kernel, will that work without any 
problems? I guess it will, but confirmation would be nice, for the peace 
of mind.

As soon as you start building i386 rpm's I will remove mine or maybe 
replace them with yours. I will be happy to test any i386 package for you.

Also if from any reason you are currently unable to build i386 versions 
you can copy from mine site if you like. It would be an honor for me. 
They are freshly compiled from your sources without ANY changes.

libvirt is also freshly compiled for i386 from your sources but with 2 
possible problems:
Error: libpci check failed
Disable KVM Device Assignment capability.
(I guess it is because of kernel<2.6.29)

2. virsh is still unable to connect to qemu:///system
