<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hello,
<div><br>
</div>
<div>we just build a new cluster with FC20 + virt-preview repos enabled.</div>
<div>Idea behind that is to enable snapshot live merge feature. This </div>
<div>seems to work quite well. </div>
<div><br>
</div>
<div>The only culprit is the Windows activation. For some reasons the</div>
<div>VM hardware of the old qemu 1.6/seabios 1.7.3 hypervisors is</div>
<div>different to the new qemu 2.1/seabios 1.7.5. So the OS is no longer</div>
<div>activated.</div>
<div><br>
</div>
<div>We already activated the VMs twice. During first install on VMware</div>
<div>and then afterwards after the migration to OVirt. <span style="font-size: 10pt;">I have no problem</span></div>
<div><span style="font-size: 10pt;">to reactivate them a third time. I have more fears that I must</span></div>
<div><span style="font-size: 10pt;">reactivate them with each new hypervisor generation. That can</span></div>
<div><span style="font-size: 10pt;">be quite a lot of phone calls.</span></div>
<div><span style="font-size: 10pt;"><br>
</span></div>
<div><span style="font-size: 10pt;">An interesting article from the Proxmox guys can be read here:</span></div>

</div>
<div><span style="font-size: 10pt;">Conclusion of the discussion: After you go from qemu 1.7 to 2.1 </span></div>
<div><span style="font-size: 10pt;">you </span><span style="font-size: 10pt;">can force the old hardware layout using </span><span style="font-family: verdana, arial, sans-serif; font-size: 11.1999998092651px; background-color: rgb(249, 249, 249);">-M pc-i440fx-1.7</span></div>
<div><br>
</div>
<div>Looking at the qemu command line in OVirt I can see our VMs</div>
<div>are fired up with pc-1.0,accel=kvm,usb=off - regardless of an</div>
<div>old (FC20) or a new hypervisor (FC20+virt-preview). So I would</div>
<div>guess that everything should work without a new reactivation.</div>
<div><br>
</div>
<div>Any ideas?</div>
