Well well, that did it!!!
For now I even restarted my host machine and the guest os boots flawlessly
now with taskset! Oh well, I now know a new nice linux app taskset :)
I saw similar problems with some games under windows, that you had to set
the affinity to a specific core, if not you were getting those kind of small
hang, like I was having with kvm and my guest machines.
And you guessed right I have a dual core cpu.
Anyone have an idea why this is only happening when using a tap network
interface? I am curious...

Ubuntu est un ancien mot africain qui veut dire "Je ne peux pas configurer
