I'm running oVirt 3.6 on EL7.<br>
<br>
In order to test nested-kvm I installed vdsm-hook-nestedvt on the hypervisor and put "fake_kvm_support = true" in /etc/vdsm/vdsm.conf.</blockquote><div><br></div> <br><br>fake_kvm_support is just for developing purposes and it's not needed as it prevent guests to run.<br><br>Please check to understand if nested support is enabled on your host:<br>/sys/module/kvm_intel/parameters/nested<br><br></div><div class="gmail_quote">if not<br> echo "options kvm-intel nested=1" > /etc/modprobe.d/kvm-intel.conf<br>and reload the module<br><br>Than install vdsm-hook-nestedvt on your hosts.<br>If you want also to use the network on your L2 guest please install and configure also macspoof vdsm hook on your physical hosts otherwise all the traffic to/from your L2 guests will be dropped.<br><a href="https://github.com/oVirt/vdsm/tree/master/vdsm_hooks/macspoof">https://github.com/oVirt/vdsm/tree/master/vdsm_hooks/macspoof</a></div><div class="gmail_quote"><div><pre style="overflow:auto;margin-top:0px;margin-bottom:0px;font-stretch:normal"><font color="#333333" face="Consolas, Liberation Mono, Menlo, Courier, monospace"><span style="font-size:15px;white-space:pre-wrap"><br></span></font></pre></div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">

However, afterwards the hypervisor host cannot connect to the ovirt Manager, on ovirt Manager the engine.log will tell:<br>

After removing the option all works well again, but I'ḿ lacking the nested kvm option :( Is nested kvm only supported on a limited cpu's??<br>
