<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I started to learn the oVirt by following the oVirt Quick Start Guide.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I used one server as the ovirt.engine, and another server as the ovirt.host. Both servers run Fedora 18.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">After executing the command “engine-setup” in the ovirt.engine, I can get into the admin portal to start the configuration of host, storage, etc. Here was what I am doing:<o:p></o:p></p>

<p class="MsoListParagraph">chown –R 36:36 /mnt/data<o:p></o:p></p>

<p class="MsoNormal">P.S. If I create the NFS domain in the ovirt.host side (i.e., Export Path is ovirt.host:/mnt/data), then everything is okay. Not sure why failed on the ovirt.engine side.<o:p></o:p></p>
