Your userspace headers dont have all the necessary pieces...
You want to add --with-patched-kernel, that should trigger an headers_sync to 
get the header files from the kernel.

Anyway, that wont give you anything useful by now, as we only have kvmlib done 
in the userspace. Until we ported the rest of our userspace part over to 
kvm-userspace, you can use our prototype code found on 

http://www-128.ibm.com/developerworks/linux/linux390/kuli.html

It supports a subset of the qemu syntax, e.g. somethin like
kuli -drive file=disks/root -megs 128 -n tap,ifname=tap0 -smp=2
works.
You might need "tunctl" and "screen" for better results. If you want to stay 
at 2.6.26 there are some kernel patches in the kuli package. They add virtio 
console support as well as a fix for the z900. 2.6.27-rc1 should work out of 
the box.
