Le but de cette tache est d'installation d'une Image Windows10 RTM dans OpenNebula

1°) Test en local sur un PC

Context:
OS : Ubuntu 15.10
CPU : Intel(R) Core(TM) i3-3220T CPU @ 2.80GHz
QEMU : QEMU emulator version 2.3.0 (Debian 1:2.3+dfsg-5ubuntu9), Copyright (c) 2003-2008 Fabrice Bellard

Iso : Windows 10 RTM (Build 10240) French
Virtio : virtio-win-0.1.110

1.1 ) Configuration en ERREUR (Ecran BSOD !)
La configuration avec cpu 'qemu64','kvm64' ne fonctionne pas !

L'installation de Windows génére :
     - une écran BSOD ( Erreur : system thread exception not handled ),
     - ou se fige sur le logo Windows (l'animation des points tournants ne s'affiche pas, puis la machine reboot)

Cette ligne confirme http://www.linux-kvm.org/page/Guest_Support_Status#Windows_Family

export WINVER=Windows10
export ISO=windows-10_finale_fr_431147_32.iso

   -k fr

1.2 ) Configuration OK :

Le test se fait avec le mode cpu = 'host'. Dans ce cas, l'installation se fait sans problème.

export WINVER=Windows10
export ISO=windows-10_finale_fr_431147_32.iso
export ARCHI=i386
[ ! -f $WINVER-$ARCHI.img ] && qemu-img create -f raw $WINVER-$ARCHI.img 25G

   --enable-kvm \
   -cpu host,hv_relaxed,hv_spinlocks=0x1fff,hv_vapic,hv_time \
   -smp cores=4 \
   -soundhw hda \
   -vga cirrus \
   -usbdevice tablet \
   -m 1536 \
   -nodefaults \

2°) Test sur un serveur OpenNebula/Hapy avec LibVirt

Nous constatons que la commande ne gère pas le cpu 'core2duo' : La ligne de commande qemu est toujours avec 'cpu qemu64'. C'est un bug dans la LibVirt : il faut trouver un contournement car cela ne pourra jamais fonctionner.
