<div>This enabled the hv_relaxed flag on all my Windows VMs, causing them to no longer boot. The same thing would happen if I simply booted from the Windows install media. I would get a screen with a stop error:</div>
<div><br>
</div>
<div>Your PC needs to restart.</div>
<div>Please hold down the power button.</div>
<div>Error Code: 0x0000001E</div>
<div>Parameters:</div>
<div>0xFFFFFFFFC0000096</div>
<div>0xFFFFF802C4044EA4</div>
<div>0x00000000000000000</div>
<div>0x00000000000000000</div>
<div><br>

<div>I created a file called /etc/ovirt-engine/osinfo.conf.d/01-windows.properties that had one line:</div>
<div><br>
</div>
<div>os.windows_xp.devices.hyperv.enabled.value = false</div>
<div><br>
</div>
<div>I restarted ovirt-engine and now I can start my Windows VMs.</div>
<div><br>
</div>
<div>Why does this occur? Is it because I upgraded from 3.4 to 3.5? Is there something else I'm doing wrong? I would like to not need this workaround. Thanks.</div>
