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

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.
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

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?
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.

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.
Thanks

Be advised that after installation is done, you can manage VMs using the ovirt webadmin.

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.

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.

As far as I remember, oVirt does come with an all in one configuration , but looks like it
was deprecated at 3.6, So can you try out the self hosted engine?

Subject: [ovirt-users] 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

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.
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.
I know this isn't a use case that oVirt or RedHat are really interested in,
but I feel it is important to expose students to real world production
software and systems as much as possible ... all we had to work with last
year was VirtualBox running on Windows 7!

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

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.
I know this isn't a use case that oVirt or RedHat are really interested in,
but I feel it is important to expose students to real world production
software and systems as much as possible ... all we had to work with last

Hello,
can you give more details about these potential locking issues? So that I

I have 2 little environments where I'm using this kind of setup. In one of
them the hypervisor is a physical server, in the other one the hypervisor
is itself a libvirt VM inside a Fedora 23 based laptop. oVirt version is
3.6.4 on both.
The test VM has 2 disks sda and sdb; all ovirt related stuff on sdb
My raw steps for the lab have been, after setting up CentOS 7.2 OS,
disabling ipv6 and NetworkManager, putting SELinux to permissive and
enabling ovirt repo:
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
if I only have to reinitialize I start from here
mkfs -t xfs -f /dev/mapper/OVIRT_DOMAIN-ISO_DOMAIN

During setup I choose:
Engine FQDN : shengine.localdomain.local
Firewall manager : iptables
Storage connection :
ovc71.localdomain.local:/SHE_DOMAIN
OVF archive (for disk boot) :
/usr/share/ovirt-engine-appliance/ovirt-engine-appliance-20151015.0-1.el7.centos.ova
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?
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.

Most of what I know about this is:

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.

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!

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.
Best regards
