<div dir="ltr"><div><div><div><div><div><div>Hi Khoi,<br><br></div>Node is the hypervizor which can run many guests (VMs).<br><br></div>We support a feature call Hosted-Engine, which allows the Node to run the Engine (the oVirt Manager) as a special type of highly-available VM on the Node(s), that it will manage.<br>( <a href="https://www.ovirt.org/documentation/how-to/hosted-engine/">https://www.ovirt.org/documentation/how-to/hosted-engine/</a> )<br><br></div>That Engine manages all Nodes that are added to it, and all VMs that they run.<br><br></div>In case e.g. Node1 fails you can simply start the VM on Node2, (as long as shared storage is used), in case of Hosted-Engine it will happen automatically - as long as you installed it on multiple nodes, which is the recommended deployment.<br><br></div>Hope that helped, if you have any further questions please do not hesitate to ask,<br><br></div>Thanks in advance, <br><div><div><div><div><div><div><div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Aug 23, 2017 at 11:05 AM, Khoi Thinh <span dir="ltr"><<a target="_blank" href="mailto:thinhduckhoi@gmail.com">thinhduckhoi@gmail.com</a>></span> wrote:<br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote"><div dir="ltr">Hello,<div><br></div><div>My name is Khoi.
