Hi Michal,

This part says libvirt was not able to insert iptables rules for a
virtual network (NAT). This can be harmless if such rules already 
exists.

This part is actually really wrong. Libvirt was unable to find any 
qemu.
Do you have any qemu installed?

I can give a try with your USEFLAGS.
Yeah, i bet it will work with them :)

Ok Ok, Tada!!!! after recompiling with the recommended useflags and 
"restarting" of libvirt = Tada!
It works!

Is the logfile informativ for you?

Btw, on my Centos6 Boxes all is running like a charme.

Well, Centos/RHEL have strict dependencies for packages and therefore
force user to install many packages which user doesn't need in the end.
That's why we are using Gentoo, right? :)

Yes, right. But for customer related server i feel good to use 
enterprise linux.

Gentoo is my personal fav and love ;-)
I wanted to give a try on latest vanilla 3.2.1 - it works like charm 
now , libvirt, virt-manager.
Only trick i have to use is, before creating new virtual machine, i 
have to a new harddisk for the vm.
When i do this in the process of creating new virtual machine, i cant 
select (in step 3?) where to define the disk.
the windows just pop up for 1 sec and is gone, i have to kill then the 
virt-manager and restart all.

what i really like is, when use Centos as Guest, u can use virtio from 
beginning on hard disk and ethernet.

E.g. on Centos it is not easy to install just libvirt without qemu.
However, it is perfectly simple to do so on Gentoo.
