C'est l'un des outils qui permettent de gérer un cloud, et fait partie des solutions open source permettant de déployer des infrastructures de virtualisation. I still didn't get to thoroughly test that part.New comments cannot be posted and votes cannot be cast.A reddit dedicated to the profession of Computer System Administration.Press J to jump to the feed. Source: I have to manage OVM.Yea, it gave me ulcers. I fucking hated it. That said, with EL7, it seems usable. I also found it easier to manage different components than KVM + virt-manager.We also built a virtualized development environment out of oVirt for a large financial institution. Engine s’installe donc sur un poste à part du cluster, l’installation se fait … Set the source from which the VM should be imported 2. It is possible to set up a VM by sort of feeling your way through however.One other point - all of the tools seem to eventually get down to libvirt and KVM (except maybe Xen), so it wouldn't hurt to get a little familiar with those if you're admining it.I actually got oVirt up and running on CentOS 7 in about 2 days, I have 5 years of RHEL/CentOS admin experience, and 3 years of Storage admin, so that sped up the process a little. It's pretty great, I'm able to spin up a basic Debian (or anything else I've made an image of) VM in about a two minutes with one command.At work we use KVM + LVM + Ceph and a bunch of custom scripts and tools to manage the various hosts and such.I'd highly recommend not to use OVM. Combine this with a PXE boot server and it becomes very easy to spin up VMs.However, if you DON'T want to run your VM servers in a cluster, vanilla KVM is the way to go. Unfortunately this can’t be done without downtime but at least it can be done. Il propose un système de gestion de cluster analogue à VMware vCenter. I'm running oVirt for a couple hundred VMs. Unlock VM & disks 1. Use the latest version of virt-v2v.I found it that virt-v2v has issues with clusters in vcenter, but I didn't spend too much time debugging it, so I still have to figure that out.Also, how did the HA work for you? IMO, any virtualization product has a learning curve, and so does VMware. The disks conversion progress should b… the only benefit we might have from it is having support on Oracle hardware. Meet Alter Way, a French hosting company who deploys oVirt in production for their clients, because "it allowed us to scale up as well as scale out our client workloads". I also see that they have nice template features, which somehow seems to work better for Linux than VMware templates.My next step is to see how I can make a working VDI environment on it using SPICE. So our CTO decided that since VMware is becoming too costly for our rapidly growing environment, we should explore other options, so of course I dove right in to it.I pulled out some of our retired Gen 8's and gave several virtualization products a test drive.The ones I tested are: vanilla KVM, oVirt, Xen, proxmox, I even looked at his request on OVM, and I found oVirt from a management and performance prospective, to be closest to VMware.It took a long time for us to get oVirt working, and we're currently still just testing it. The other common tool, OpenStack (which I think has the most momentum behind it), isn't really the same sort of thing IMHO, and very focused on private or public cloud. Update VM & disks if necessary (update actual disks size for example) 10. (HP I am assuming...).Yea, they are being downgraded to lab/playground, gen9's are prod for over a year now.I'm lucky, I know, thats why it's great to work for a multi-billion dollar privately held company, no reporting to investors.I built an oVirt environment out of two nodes to replace our vanilla KVM installation, with no prior experience in setting up systems like these. However, if you DON'T want to run your VM servers in a cluster, vanilla KVM is the way to go. Learn how to use the "virt-install" command (bonus points if you can AUTOMATE this command, and automate the install process), and you can stand up new VMs in 10-15 minutes on good hardware, without a PXE server. Alter Way. Taking advantage of the API and VM replication, we managed to reduce their original environment replication (3 VMs) from three weeks to just one weekend (the VM images were huge, but we developed a way to do it in less than a day).On a side note, it is not difficult to convert VMWare images to ovirt-compatible images. oVirt est un logiciel de gestion de plateforme de virtualisation open source créé par RedHat en tant que projet communautaire. oVirt is a free and open-source virtualization solution for designed for running large-scale and mission critical workload on production environments. Essentially OVM is bodged lobotomized version of Xen. However, now that it's working, the WebGui is pretty point and click, but still non-intuitive.
