Educational use case question
Hi I am teaching IT subjects in TAFE (a kind of post-secondary technical college) in Australia. We are currently looking for a virtualisation platform that will allow students to install and manage VMs via web interface. VMware is being proposed but I am trying to get KVM and the RedHat ecosystem in the lab as much as possible. I have reasonable experience with running virt manager on CentOS 7, but oVirt is new. I have it installed and running OK but am not sure how to proceed with configuration. I basically want to run a single physical server which will be the KVM host, the ISO and data store, and the home of oVirt engine ... in other words a complete oVirt-managed KVM virtualisation platform running on one physical machine (32GB RAM). It will only ever need to run a handful of VMs with little or no real data or load. Is this possible/feasible? If possible/feasible, where should oVirt engine go ... on the host itself, or into a VM guest? The web interface is what is making oVirt an attractive option at this stage, as students will be working from Windows clients on a corporate network. Do VM GUI display well in the browser? Thanks for any advice Mike Hall
Hey Michael,
I am teaching IT subjects in TAFE (a kind of post-secondary technical college) in Australia.
Great news for this tech to be in tafe. I remember my time at Logan tafe got me into linux.

If it was me, I would do the engine install on the metal host itself. Will be a lot easier for you, as long as you _know_ you will not be adding more metal nodes to the oVirt setup. I would also be looking into the "VM Pool" feature for your student. This will give you a pool of VMs which after use can be reset to a default configuration.
The web interface is what is making oVirt an attractive option at this stage, as students will be working from Windows clients on a corporate network. Do VM GUI display well in the browser?
I have no experience using oVirt from Windows, but if there is a splice client available I see no reason why it shouldn't work. If you're local to QLD, I am more then happy to help in person. --julian
Thanks Julian, I'm in Mildura in VIC. I was hoping for a "pure" web-based client console solution, not something like the VMware desktop client. Anyway, I'm not going to get too hung up on this. Even if we go VMware because it "just works" and everyone's happy with it, we'll still do plenty of CentOS/Fedora. There is also a case to be made that our students are much more likely to encounter VMware in a corporate environment that KVM. And Windows. And iPads. Yawn.

Yes but what about the student sitting on the Windows machine in the lab who wants to install and interact with her VM via it's GUI ... like is possible in Virtual Machine Manager on RHEL/CentOS 7 ... except she'd be doing it remotely via an in-browser console ... like Digital Ocean do for example.

This certainly works. Console can be reached via a browser plugin or Virt-Viewer (available for Windows). Self-hosted engine is the way to go, and is production-ready, especially if you want to add more nodes later. On 14/04/16 03:33, Michael Hall wrote:

I dont think digital ocean is the correct analogy. As a digital ocean user, I have console in which I can create vms, right? But who installed the virtualization software for that? If you're thinking of a digital ocean, the analogy should be a provider that exposes ovirt web admin/user portal as management console to its customers.

Thanks for the response. I did see that page and certainly agree with the point under "Benefit to oVirt" heading: "This operational mode will attract users already familiar with it from other virt platforms." I'm happy building headless servers using CLI over SSH, but my colleague and students aren't and need a "nice" point and click web interface which will display a usable VM desktop etc. My colleague is most familiar with VMware. But the project doesn't look ready to go and I can't find a download.

Hi
I am teaching IT subjects in TAFE (a kind of post-secondary technical college) in Australia.
We are currently looking for a virtualisation platform that will allow students to install and manage VMs via web interface.
VMware is being proposed but I am trying to get KVM and the RedHat ecosystem in the lab as much as possible.
I have reasonable experience with running virt manager on CentOS 7, but oVirt is new. I have it installed and running OK but am not sure how to proceed with configuration.
I basically want to run a single physical server which will be the KVM host, the ISO and data store, and the home of oVirt engine ... in other words a complete oVirt-managed KVM virtualisation platform running on one physical machine (32GB RAM). It will only ever need to run a handful of VMs with little or no real data or load. Is this possible/feasible?
If possible/feasible, where should oVirt engine go ... on the host itself, or into a VM guest?
The web interface is what is making oVirt an attractive option at this stage, as students will be working from Windows clients on a corporate network. Do VM GUI display well in the browser?
Thanks for any advice
Mike Hall

I did see that page and certainly agree with the point under "Benefit to oVirt" heading:
"This operational mode will attract users already familiar with it from other virt platforms."
I'm happy building headless servers using CLI over SSH, but my colleague and students aren't and need a "nice" point and click web interface which will display a usable VM desktop etc. My colleague is most familiar with VMware.
But the project doesn't look ready to go and I can't find a download.
The page mentioned is the "feature page" written during development. This is in production for 2+ years now, and the page you should follow is: http://www.ovirt.org/documentation/how-to/hosted-engine/ Also keep in mind: 1. There are some requirements not included in ovirt that you'll have to supply yourself, including: - shared storage - usable name resolution - usually meaning dhcp+dns, with dns pre-populated with back (and forward) records for the addresses in the dhcp dynamic range, so that your guest OSes get these as hostnames (and not end up all having hostname 'localhost', which is probably confusing for users). 2. The expected use-case of ovirt is a larger system, consisting of more than one physical server, and dedicated storage. If you still want everything on one host, you basically have two options: 3. NFS loop-back mounting nfs is considered risky, due to potential locking issues. Therefore, if you want to use NFS, you are better off doing something like this: 3.1. Have the physical machine managed by kvm (virt-manager, virsh or whatever) 3.2. Have a VM serving as an NFS server 3.3. Have another VM (or more than one) serving as a "host" using nested-kvm 3.4. Either have the engine on another VM on the physical machine, or use hosted-engine on the virtual host(s). 4. iSCSI iscsi does not suffer the same locking issues when loop-back mounting, so in principle you can run hosted-engine directly on the physical host with part of the disk shared using iSCSI and loop-back mounted. You can still use the setup described above in "NFS", with the main benefit being (I think) easier migration to more hardware if/when needed. With any of the above, once you finish the setup, everything else should be at least usable using the web interface. Re console access - there is a "novnc" spice client that is pure HTML5 and runs in your browser. I don't think it's used much, but should work. There is also a websocket-proxy component allowing access from places that can access the proxy but can't access the hosts. But most people probably use native clients, usually remote-viewer or the browser plugin. Best,
Also, an implementation that isn't stable and fully functional will probably do more damage than good as far as open source's rep in our lab goes.

Most of what I know about this is: https://lwn.net/Articles/595652/

selinux enforcing should work too, if it fails please open a bug. Thanks. You might have to set the right contexts for your local disks.
NOTE: I also stop and disable firewalld
My host is ovc72.localdomain.local and name of my future engine shengine.localdomain.local
yum -y update
yum install ovirt-hosted-engine-setup ovirt-engine-appliance
yum install rpcbind nfs-utils nfs-server (some of them probably already pulled in as dependencies from previous command)
When I start from scratch the system
pvcreate /dev/sdb vgcreate OVIRT_DOMAIN /dev/sdb lvcreate -n ISO_DOMAIN -L 5G OVIRT_DOMAIN lvcreate -n SHE_DOMAIN -L 25G OVIRT_DOMAIN lvcreate -n NFS_DOMAIN -l +100%FREE OVIRT_DOMAIN

Also, I used the appliance provided by ovirt-engine-appliance package
After install you have to make a dependency so that VDSM Broker starts after NFS Server
In /usr/lib/systemd/system/ovirt-ha-broker.service
Added in section [Unit] the line:
After=nfs-server.service
Also in file vdsmd.service changed from: After=multipathd.service libvirtd.service iscsid.service rpcbind.service \ supervdsmd.service sanlock.service vdsm-network.service
to: After=multipathd.service libvirtd.service iscsid.service rpcbind.service \ supervdsmd.service sanlock.service vdsm-network.service \ nfs-server.service
NOTE: the files will be overwritten by future updates, so you have to keep in mind...
On ovc72 in /etc/multipath.conf aright after line # VDSM REVISION 1.3
added # RHEV PRIVATE
blacklist { wwid 0QEMU_QEMU_HARDDISK_drive-scsi0-0-0-1 wwid 0QEMU_QEMU_HARDDISK_drive-scsi0-0-0-0 }
To exclude both 2 internal drives... probably oVirt keeps in mind only the first one?
No idea
Otherwise many messages like: Jan 25 11:02:00 ovc72 kernel: device-mapper: table: 253:6: multipath: error getting device Jan 25 11:02:00 ovc72 kernel: device-mapper: ioctl: error adding target to table
So far I didn't find any problems. Only a little trick when you have to make ful lmaintenance where you have to power off the (only) hypervisor, where you have to make the right order steps.
I guess you can probably script that too... Thanks for sharing. As wrote above, no personal experience with loopback nfs. For the multipath question, if interested, perhaps ask again with a different subject. thanks for sharing! -- Didi
Hi,
But the project doesn't look ready to go and I can't find a download.
I think that is one of the unfortunate effects of how the website was converted. Check the At a glance section, it says the status is Released. We have had it released since oVirt 3.3 with significant improvements in 3.4 and 3.6. It is used in production world wide now. That said.. we have a deployment related bug in 3.6, but all should be perfectly fine if you have just a single host.
