Hi Uri,
I have install 2.6.19.2 kernel in Red Hat and I have got .ko files at 
last !!
But it seems if there is a problem when I try to load the module:

modprobe kvm-intel
FATAL: Error inserting kvm_intel 
(/lib/modules/2.6.19.2/extra/kvm-intel.ko): Operation not supported

I have tried to load "kvm" one (without intel extension) but I suppose 
it is not right becase qemu fails:

/usr/local/kvm/bin/qemu -hda vdisk.img -cdrom 
/var/tmp/ubuntu-6.10-server-i386.iso -boot d -m 384
open /dev/kvm: No such file or directory
Could not initialize KVM, will disable KVM support

I need your help again.
Thanks a lot.

Frank
