Hello,
I'm French, I work for the French administration and this is my first
message on this list...
At the moment, we use VMware (vSphere 5.1/5.5, cloud edition) for our
virtualized complex infrastructures.
I've discovered recently that oVirt offers enhanced features, closed to
the ones of VMware. Is the product sufficiently advanced yet ? I don't
know and I hope you'll be able to help me ;-)
My first question is about hypervisor... In VMware infrastructures, we
use a microkernel since the version 4 (before, it was an hypervisor
based on a RedHat core).
On the oVirt site, I can download ovirt-engine to install it over
Debian/RedHat/CentOS, etc... But it seems to be less optimised because
some ressources are used by the underlying OS...
Can you explain me differences between this technology and the VMware
one ?
Thank you.
David.

Welcome David,
We find it sufficiently advanced, since 3.5 is nearing release most of
our wishlist has been taken care off ;-)

Ovirt engine is the management

it to be that optimized as it's not running VM's itself.

Yes, it is an interesting article even if I did not understand the
Openstack point because, if I'm not wrong, Openstack can run over any
virtualization solution, VMware, KVM, etc...

Yes, I saw my mistake between oVirt engine and oVirt node ;-)
My really question was : is it a good idea to run the oVirt node over
another OS ? It would be more performant to run the oVirt node directly
over the hardware, like ESXi...
May be it is in the roadmap ?
And I have another question : is there something like VMFS to store the
VM in the SAN ? It's more performant to use FC than NFS shares...
Thank you.
David.

VMware says esxi is a bare-metal hypervisor and there is not an underlying
os. Someone else says it is based on vmkernel operating system ( where
vmkernel is defined as a posix-like operating system).
In my opinion the oVirt node is to be intended something like ESXi: an os
with the smallest possible footprint, dedicated to run as a KVM hypervisor.
The difference being that it is based on Linux and not developed from
scratch.

FYI:
actually the vmware kernel leverages many open source drivers
from the linux kernel and I highly suspect that it is in fact
a custom linux kernel.
some evidence that supports this view is the recent
attempt of vmware to join the linux-distros mailinglist
to get early access to vulnerabilities in open source code.
you can just join this list if you offer a kind of "linux" distribution
(or something very close to it).
here is a thread for further reading on the case:
http://seclists.org/oss-sec/2014/q2/403
PS: regarding ovirt-node:
it's actually a very trimmed down linux system, just enough
to act as an hypervisor, so it's bare metal virtualization
(I would even argue that there is no such thing as a type 1
hypervisor, because if you talk about type 1 hypervisors
the hypervisor itself is the operating system kernel, which is also
the case for kvm, as it is a linux kernel module).

There is only this part I do not understand !?!?

First, I second Sven's view, there is
no such thing like a type 1 HV (so
'hardware' only). I used oVirt node 3.4 and it works really well and
sable. If you compare it with ESXi, you will feel it is very similar
(even the screen telling you system basics if you attach a monitor to
it).
ovirt node was developed later on, to you basically have two options:
- The 'classic' option: install a basic os (centos6 minimal or fedora 19
minimal) and install the ovirt packages via yum, then run ovit node
setup; done.
- run ovirt node iso, install it to disk. This leaves you with a system
wich has to be managed from ovirt engine, because all changes you make
manually do not survive a reboot (normally).
While I think using ovirt node is the best option for deploying HV-nodes
there is one major drawback: It does not support hosted-engine-ha atm;
but I think this feature will make it into ovirt node 3.5.
There is only this part I do not understand !?!?
So bottom
line, ovirt node is the same as option 1; but more tailored to
complete management from ovirt enginge.

Thank you.

David.

VMware says esxi is a bare-metal hypervisor and there is not an
underlying os. Someone else says it is based on vmkernel operating
system ( where vmkernel is defined as a posix-like operating system).
In my opinion the oVirt node is to be intended something like ESXi: an
os with the smallest possible footprint, dedicated to run as a KVM
hypervisor. The difference being that it is based on Linux and not
developed from scratch.
It is OK for me to have an oVirt node similar to ESXi, except that it
is based on Linux.
But on the oVirt site, I've found oVirt node packages to install over
RH, Fedora, Debian, CentOS, etc...
Is there a "dedicated" oVirt-node ISO, based on the Linux kernel, but
optimized for KVM, without other kernel modules we can see on RH,
Fedora, Debian, CentOS, etc... ?
Thank you.
David.
2:55 p.m.
I don't actually use it myself so
take my information with a grain of salt, as it might not
be 100% accurate.
afaik this is the current stable ovirt-node iso:
http://resources.ovirt.org/releases/3.4/iso/ovirt-node-iso-3.4-20140423.0...
it comes in 2 flavors: el6 based and fedora based.
so it's actually a trimmed down el6/fedora version
I cc'ed fabian who can give more information on the
case, because he is the maintainer of the node project
(i hope this is still correct).

Not yet, and I don't know if it is on the roadmap.
you could maybe create your own, it's basically
this workflow:
install $distro
throw out all unneeded stuff
install virt stuff (libvirt+vdsm)
apply hardening (selinux etc)
create iso
I go with centos minimal and customize
that myself, works really well.
I don't know if vdsm is already complete
platform independent (afaik it should be).
the initial development was all on fedora
and el6, so this is where it runs best atm.
but I know for sure there are plans to
make it distribution agnostic, but
I don't know if this includes a pre-created
iso for ovirt-node based on debian or gentoo.
maybe fabian can shed some light on the
future plans.
alon can maybe give some insight into
how distribution agnostic ovirt already is
and what future plans are,

No. Currently not.

The current Node can really only be created for Fedora related distrios, so CentOS, RHEL
and Fedora itself.
The reason for this is that all parts "the build process" is tailored around
Fedora related tools. Namely kickstarts, and lviecd-tools.
We are currently thinking about how we can change Node and make it more friendly, the
distro agnostic idea also goes into this thoughts - but there is nothing concrete on that
front yet.
That's it from the Node side.

By the way David have you ever done a Red Hat kickstart with the nobase option.
You get an OS install thats as stripped down as possible. you can even
create a node for ovirt which is smaller than the ESXi install base
last I checked. just be aware you will not have many of the tools you
would normally expect to see for example bind-utils isn't installed so
the box wont have nslookup or dig unless you install it.

Hello,
If I understand well, the ISO node is the best solution to have the
"smallest" OS, but maybe I will have problems with some functions, like
SSH keys, integration with Centreon, etc... Daniel Helgenberger said :
"all changes you make manually do not survive a reboot".
So, the best option is to install a basic OS (for me, a Debian one),
and then, to add oVirt-node packages...
Now, let's go ;-)
Thank you.
David.

oVirt is not distro-agnostic at all.
It is very specificaly designed in the redhat universe (-> rhel, centos,

Love yourself, try it on CentOS.

though if you can help make it better on debian, we'd welcome the help.

oVirt-node is not installed "on an OS", its an image you install on bare
metal. ovirt node is a trimmed down .el6 with the necessary packages to
be managed by ovirt.
you can choose to use normal .el6/fedora, and use them as hosts via the
engine gui, it will deploy/configure these packages as well.
