<div>During the first boot after sysprep, Windows disinstalls and reinstall drivers based on PNP, but this is unfortunately having issues on XenServer/XCP so our Cloudbase-Init unattend.xml used during sysprep avoids removing the drivers on boot. </div>

We still have to test a XenServer/XCP image booted on Hyper-V, but it's IMO a feasible way to go.</div>

Subject: Re: [Openstack] [HyperV][xen] Porting Windows disk_image from xen to HyperV<br>
<br>
I forgot to mention that I found this doc mentioning how to migrate <a href="http://jeff-brady.blogspot.com.br/2011/12/linux-on-hyper-v-migrate-redhat-vm-from.html">
http://jeff-brady.blogspot.com.br/2011/12/linux-on-hyper-v-migrate-redhat-vm-from.html</a><br>
<br>
*But* I'm more concerned for the aspect of driver-wise.<br>
Technically a xen-to-hyperV image will boot, would it be auto-suficient?<br>
<br>
I mean, would I have to reinstall all drivers ?<br>
<br>
thanks<br>

<blockquote type="cite">Hi guys,<br>
<br>
I've got a quick question regarding HyperV and Xen virtualization <br>
modes and their compatibility.<br>
<br>
Can you help me out on this? Here's the deal:<br>
<br>
Knowing that when xen boots up a Windows box, it goes as "HVM" <br>
(Hardware Virtualization) but needs some "PV"<br>
(Paravirtualization) drivers...<br>
<br>
And that Hyper-V *does* work with Windows in HVM (without the <br>
PV-drivers), theorically and tecnically, is there a way I could have a <br>
"Windows Server" which the disk_image is xen-based ported to HyperV ? <br>
Even if I have to apply some process in the way<br>
<br>
Thank you!<br>
<br>
