[ovirt-users] Start VM automatically
Hello, My node (IP ovirtmgmt) is behind a routeur that is running on the hypervisor (the node itself). So, I need that the VM (routeur) start automatically after the node start. The ovirt engine is running on another infrastructure and the version is 4.2.0. The node is also in this version. Is there a solution ?

Re: [ovirt-users] Start VM automatically
Hi Hanson, Thank you for your answer, but the routeur is a VM. So I need that this VM start without the engine. It has to start when the node start (after a power failure). Only when the routeur will be up, I will be able to manage the node and the VMs. Do you think there a solution ?

In the highly available section, (edit the advanced options on the vm) you can set the resume options restart/resume/stay off The engine needs to be able to see + manage the node. You'll have to take care of the networking/port forwarding/vpn/vlan etc to make sure the engine can control the node. Once the node's in control, the engine can restore the VM when it knows the node is good.

Obviously this a bit more "chicken-and-egg" than running a hosted engine. Even if there was a "start automatically" sort of thing, this is still going to be fraught with potential issues, because almost anything could happen to prevent the "router vm" from starting. I think you've created a fairly high risk scenario. In other words, even if you got this working, I wouldn't trust it. Just my opinion. At a minimum I'd pull the "router" out of the VM stack. Now, you could have a separate hypervisor cluster stack for the router, just don't put it's mgmt engine (separate engine req'd) behind the router :-) Sincerely, Fabrice Le 26/02/2018 à 18:18, Hanson Turner a écrit : Hi Fabrice, If there's an issue with the hypervisor, the VM should pause.

Re: [ovirt-users] Start VM automatically
Hi, we are considering the feature and its many angles: - starting without the management using local storage ( https://bugzilla.redhat.com/show_bug.cgi?id=1166657) - starting without the management with shared storage ( https://bugzilla.redhat.com/show_bug.cgi?id=817363) - starting the VM via the management running as Hosted Engine ( https://bugzilla.redhat.com/show_bug.cgi?id=1325468) All three cases have their pain points eg: which host should start the VM and how do you protect against split brain? If you would be so kind, please describe your use case to the relevant RFE bug so we can consider it when planning the feature. And stand assured that we are thinking about how to implement this properly.

Re: [ovirt-users] Start VM automatically
Hi, We want to install ovirt for every school in Guadeloupe (~70 schools) Each school has an internet connexion with a basic physical router (no vpn). We have bought one physical server for each school. We have installed an ovirt engine on our central site where we want to manage all the node which are in the school. In first, for the tests in laboratory, I have installed a node behind a routeur. The routeur forwarded all the traffic from the ovirt engine to the ovirmgmt ip address (NAT). It works but I cannot have access to the VM consoles : my Spice client try to access directly to the node private IP address. Is there a solution to resolv this ? In ovirt documentation, I read "Spice Proxy" and "Websocket Proxy". Could these features answer to this problematic ? In the ovirt engine, is it possible to provide a NAT address to the node ? then the VM consoles coud work. So, I give up the above architecture and move my ovirtmgmt ip address behind a VM routeur which has a tunneling IPSec to our central site. The access to the VM consoles is resolved but I discover that the VM does not start automaticaly whithout the engine (like vmware does). I hope you understand my problematic.

You can overwrite the console ip at cluster -> console. Try to put there the external ip and have NAT correctly set. This should work.
