[one-users] Private cloud with Front-end on Virtual MAchine HA
Hi all, someone have some documentation for a sample of private cloud structure with: - Two nodes in HA - Front-end on virtual machine HA With storage file system on glusterfs Thanks all..

Re: [one-users] Private cloud with Front-end on Virtual MAchine HA
Thanks so much Bart, That's the case. because vm running on cluster is more similar to VMware HA solution (only two hosts without front-end) For the glusterfs i've already used this solution on my public cloud with success. You helped me for port-setup of hypervisors :) I hope (like you) that someone (users or OpenNebula Team) have best practices on how to run OpenNebula in a VM. Thks. Giancarlo Il 13/11/2014 11:38 Bart ha scritto: Hi, Do you mean to have the frontend (OpenNebula management) running on the actual OpenNebula cluster? If that's the case then I would also be very interested in this scenario :) As for GlusterFS, we've followed these instructions with success: * http://docs.opennebula.org/4.10/ [2] * http://docs.opennebula.org/4.10/administration/storage/gluster_ds.html [3] Also, all other instructions that we found were also on the documentation site. With it, we've created the following: * GLUSTERFS: Two storage hosts (running CentOS 7) in the back-end which provide the whole image/datastore for OpenNebula. HA is setup via round robin DNS. After testing we've found this to work quite well in terms of performance and redundancy (better then expected). All network ports are setup as a bond using balance-alb. * HYPERVISORS: a.t.m. 4 hypervisors (will eventually grow to 8) running CentOS 7. They have 2 network ports setup using bonding with balance-alb, they are connected to the virt/storage VLAN. And two network ports setup in a bond using active-backup, this is used for the bridge port (with VLAN tagging enabled). Active-backup seems to be the proper setting for a bridge port since a bridge can't work that well with balance-alb. * OPENNEBULA MANAGEMENT NODE: This includes the OpenNebula daemon, sunstone and all other functions. Currently, since we're building up this environment. Hypervisors and storage have been arranged and we're happy with how those parts are setup, however the management node is currently still something we're not very sure about. We're considering buying two physical servers to do this job and create an active backup solution as described in the documentation: http://docs.opennebula.org/4.10/advanced_administration/high_availability/oneha.html [4]. However, buying hardware just for this seems a waste since these servers won't be doing that much (resource wise). * We do have plans on testing this node, dual, on the actual OpenNebula cluster. But something is holding us back. I can't find any proof of someone achieving this. Also, we're seeing some issues that might occur when OpenNebula is managing itself (e.g. live migration, reboot, shutdown, etc.). * VIRTUAL MACHINE HA SETUP: We haven't actually started with this part yet, but this document describes on how you can create a setup where virtual machines become HA: http://docs.opennebula.org/4.10/advanced_administration/high_availability/ftguide.html [5] For us this is something we'll probably start looking into once we've found a proper setup for the OpenNebula management node. Hopefully this info helps you a little and I also hope someone else can elaborate on running OpenNebula as a VM on it's own cluster. Or, at least other best practices on how to run OpenNebula in a VM without buying two physical servers for this job, (any insight on this subject would be helpful :) -- Bart 2014-11-13 9:50 GMT+01:00 Giancarlo De Filippis gdefilip...@ltbl.it: Hi all, someone have some documentation for a sample of private cloud structure with: - Two nodes in HA - Front-end on virtual machine HA With storage file system on glusterfs Thanks all..

Re: [one-users] Front-End node
Thanks very much for rapid answer. Is possible to have a doc for installation of front-end as VM in one host (already in one cluster???) And can onenebula manage yourself (manage the vm installed in node)? We have a shared filesystem with glusterfs ... sorry for my english!! ;) Il 17/12/2013 15:10 Steven Timm ha scritto: OpenNebula Frontend in a VM It can be done, but how well it performs depends on what data store you are using. We do it in our development OpenNebula cloud but not in production yet because we are using a shared image store with GFS2 and CLVM and it is difficult with our current situation to get a VM to be a member of a cluster like that, particularly since our fibre channel host bus adapters don't support pass-through. We are exploring other options for our data store as we migrate to OpenNebula 4 series so we can make it work more smoothly. With NFS data store or ssh-based data store I expect you would not have any problems. So right now in the meantime our high availability OpenNebula head nodes run on bare metal, in an active-passive configuration, using Red Hat Clustering to manage the high availability of the service. HA is not perfect--if one head node goes down while a VM operation is in progress, the other one will not pick it up, but it's good enough for most thiings. There was a High Availability guide recently published. http://opennebula.org/documentation:archives:rel4.2:oneha [1]We were doing most of this stuff in version 3 before it was formalized in the guide.
