Sure, you can use all-in-one plugin for having both running on the same node. In 3.4.0 you'll be able also to run ovirt engine inside a VM using hosted-engine feature. Also note that doing this manually, not using the all-in-one plugin, is unsupported and might cause problems (iirc _will_ cause). Meaning: Do _not_ do the following: install and setup engine, then add the host it's on as a host. If so any down side ? You'll have less resources available for VMs on the host running the engine. It's also a bit more complex, and generally considered suitable only for very small installations (just one machine) etc. With hosted-engine, even if you start with a single host, if you add one in the future, you'll be able to migrate the engine VM to the other host and have HA for it. -- Didi -- *Hans Emmanuel* *NOthing to FEAR but something to FEEL..* ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[Users] Limit bandwidths for VM
Hi all, I was thinking whether it is possible to limit bandwidth used by a particular vm ? So that we can make sure that its not eating up bw for other vms also. -- *Hans Emmanuel* ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] Ovirt DR setup
Thanks for your reply . Yes we can replicate storage data with Gluster geo replication . Then what should be strategy for replicating Ovirt Engine confs and db ?
