Re: [ovirt-users] ovirt-hosted-engine-setup and single machine install
Hello Roman and Simone, thanks for pointing me in the right direction. I just messed up the first attempt by selection the wrong interface during the install. But I think I get the overall picture.

To be fixed in 3.6.1. See: https://bugzilla.redhat.com/show_bug.cgi?id=1269768 Also, if you plan to have a single host and you use NFS for storage domains on your single host, you have to manually change /usr/lib/systemd/system/ovirt-ha-broker.service so that in the [Unit] section it looks like: [Unit] Description=oVirt Hosted Engine High Availability Communications Broker After=nfs-server.service otherwise ovirt-ha-broker will fail to start and you have to manually start it after boot and nfs service has come up.

You will then also see the hosted engine VM as a special VM in the VMs tab of the web admin portal.

[ovirt-users] ovirt-hosted-engine-setup and single machine install
Hello All, after configuring a first setup, based on the quick start guide, I'm now looking at the hosted-engine setup. My question is: after I do the hosted-engine-setup, how do I setup vm's on the same machine that hosts the now-virtualized engine?
