Hi all, ready for a story? (well, more of a rant, but hopefully it will be a
good UX tale, and may even be entertaining.)
Had one of the groups come to me at work this week and request a OpenStack
setup. When I sat down and discussed their needs, it turns out that they
really only need a multi-hypervisor setup where they can spin up VMs for
their research projects. The VMs should be fairly long-lived, and will have
persistent storage. Their other request is that the storage should be local
on the hypervisor nodes (they plan to use Intel servers with 8-10 2TB drives
for VM storage on each node.) They desire this in order to keep the VM I/O
local - they do not have a SAN of any sort anyhow, and they do not care
about live migration, etc.
In any case, knowing that they did not want to afford a VMware setup (which
is what I'm used to using), I proposed using oVirt to fill their needs,
having heard and read up on it a bit (It's "open-source VMware", right?)
even though I had not used it before (I have however made single-node KVM
hypervisors for their group before, utilizing Open vSwitch, libvirt,
virt-manager etc., so I'm not completely ignorant of KVM/libvirt etc.)
In any case, I took one of their older servers which was already running
CentOS 6.5, installed the requisite packages on it, and in short order had
an engine server up and running (oVirt 3.3.2). That seems to have been the
easy part :-/ Now came the installation of a hypervisor node. I downloaded
and burned an ISO of the latest oVirt node installer
(ovirt-node-iso-3.0.3-1.1.vdsm.fc19.iso) and tried to install it on one of
their target Intel servers. On the 1st try I got to the end of the setup
TUI, invoked the Install link, and was promptly thrown an error (sorry, but
forgot what it was, something like "press X for a command prompt, or
Reboot".) No problem, I rebooted, selected booting off the CD again, waited
until the TUI came up, and when I tried to move past the first screen, it
threw me out to a login prompt. OK, enough of that (the server takes a long
time to reboot, and then boot off the CD) - I then thought I would try it on
a VMware Workstation VM (yes, I get the irony, but VMware wkstn can handle
nested virt, so it's a great testbed platform for OpenStack, etc.) because
that would install a heck of a lot faster. That went a lot better - got the
oVirt node 3.0.3 installed on the first try.
More pain was soon to follow, however. I logged in and started configuring
the node. The TUI was easy enough - much like an ESXi node ;) I set the NIC
to IPv4 static, entered in the correct IP info, registered a DNS name for
the IP I had assigned, and then tested pinging the engine, all was good. I
then moved on to the section where you define the engine. I entered in the
FQDN of the engine, verified the key fingerprint, and clicked the "Save and
Register" link at the bottom. That seemed to work, so I completed the rest
of the TUI, and then looked at the oVirt engine web UI. There was my new
node, ready for authorization. I clicked the link to authorize it, and after
a while, the UI came back with "Install Failed" status. Hmmm. So I went back
to the node's TUI, and now some of the screens said that the IP addr was
unconfigured? I went then to the Network screen, and sure enough, the NIC at
the bottom showed "Unconfigured". WTF? So I went and entered in the correct
info back in the IPv4 section, and then arrowed down to the Save link and
clicked it - and the next screen said something like "No info needing
changes, nothing to do." Whaaaa? Went back to the network setup screen, NIC
still showing "Unconfigured" even though the IPv4 info still was there. I
did a ping test at this point from the Ping link on the network setup page,
and what do you know - I could still ping IP's (the engine, the default gw,
etc.) But as I moved around the TUI, other screens still said that the
network was unconfigured. Went back to the Web UI of the engine, put the
host in Maint, then tried to Activate it, still no go - Install Failed. Even
though I had configured the node to allow remote access and set a password,
and also verified via nmap that TCP port 22 on the node was indeed
listening, when I tried to SSH into the node as admin, I immediately got a
"connection closed" message, so that failed as well. Went back to the
node's
network setup page, set the IPv4 to "Disabled", saved it, then went back and
set it back to "Static" then re-entered the IPv4 info. Clicked the Save
link, it went thru the setup again, came back with a success, verified with
ping etc. that networking was working on the node. The engine web UI still
said that it could not connect to the node however. So I put the node in
Maint, and then removed it. I went back to the node, went to the Engine
setup page, and re-did the screen to define the engine on the node. I notice
that after I did this, however, that the node screens went back to saying
that the network was unconfigured. Grrrrrr. But the node was back in the
engine's Web UI, however no joy this time either - "Install failed" again.
Well, the hell with this, said I - I removed the node again from the engine,
and went and installed Fedora 19 minimal install on the VM, so I could use
the directions found in
http://www.ovirt.org/Quick_Start_Guide#Install_Fedora_Host and give that a
try. (At least I can see what's going on with the node's OS using F19.)
Installing F19 on the VM was a breeze, then logged in as root and did the
"yum localinstall http://ovirt.org/releases/ovirt-release-fedora.noarch.rpm"
which ran fine. I then stopped firewalld, and set it not to run at boot
(which is what we typically do anyhow for internal research servers.) Then
went over to the engine UI, and manually added the node. Oh happy day - the
node seemed to install OK - it had the status of "Installing" for quite some
time, and I looked at the processes on the F19 node, and could see python
installer programs running via an SSH session from the engine. HOWEVER, at
the end of the process, the Web UI reported a status of "Non Responsive",
even though the F19 node looks OK (it had sanlock, supervdsmServer, vdsm
processes running.) So thinking that it may take an after-install reboot, I
did that, waited until the node came back up again, then clicked in the
engine web UI and executed the "Confirm 'Host has been rebooted'"
command,
but still no good - the node remains in "Non Responsive" status.
So I have no idea on how to proceed now, and what methods I can use to try
and debug the connectivity problem between the engine and node. And there's
many miles to go in setting up the whole environment. Maaaaaybe OpenStack
would be easier ;-P No, I will press on and try to get this thing
working... It seems it works for others, and looks like the right fit for
the job. Just wish it was easier to get up and running.
Oh yes, I tried reading the docs - go to
http://www.ovirt.org/Quick_Start_Guide#Install_Hosts and click on the link
for "see the oVirt Node deployment documentation." Not too helpful... (Bug
report has been opened.)
Thanks for reading, and any clues on getting a node up and running
gratefully accepted...

If the installation ends, either with or without error, it will give you
a log location. Upload the log to a paste.bin and mail the link.
@Gabi,
There should be more info in either the vdsm.log on the SPM server or in
the engine.log on the engine server, see above for lettings us know what
the error is.
Having installed oVirt, probably dozens of times, I have some guidelines:
- temporarily disable firewalld/iptables (if all works, enable should
still work, scripts with rules are generated and location is given)
- make selinux permissive either via setenforce 0 (until next boot) or
via /etc/selinux/config ( survives reboots), dont disable it!
- make sure fqdn work in both directions between engine and host(s)
(either using /etc/hosts or DNS)
- make sure NetworkManager is disabled and network enabled

Hi Joop,
1. I did disabled firewalld/iptbles on both nodes and engines.
2. Disabling selinux: when setting to permissive via /etc/selinux/config
(and of course unpersist/persist them -> /config/etc........) doesn't work
( as write this I've just reboot one node with the above modification and
when I try to ssh node I get "connection closed by..." - of course selinux
is enabled; after setenforce 0 ssh is OK.The only way I manage to diasble
selinux was
mount -o.rw,remount /run/initramfs/live
edit grub.cfg and add selinux=0 to kernel line
3. one strange issue: after I reboot nodes, trying to ssh raise ssh warning
WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! " so I have to remove host
entry from .ssh/.known_host in order to connect
4. I am about to check name resolution
5.I have glusterfs also on both nodes. After I put nodes on maintenace,
stop gluster volumes and rebooting nodes caused gluster volumes to
dissapear from engine web interface
Thanks

Hi,
my advice would be the following:
for "nodes" use either a "full"
minimal centos or fedora and install ovirt.org
repo on top of that.
then everything works.
the "node.isos" provided by ovirt are in pre-alpha
state to be honest.
sure you still have to disable selinux
(or better configure it correctly).
But you have no problems with configurations which are
not persisted and as a bonus you can install
$your_favourite_tool on the node, such as tcpdump
nmap etc. for debugging.
Again: I would strongly advise against useing
the node.isos from ovirt.org at the moment.
There is just too much stuff not working
or bugged, even simple things like network
configuration.

Docs should be updated with a warning then as to the "alpha" status of the
ovirt-node product... It was a huge time-sink for me.

Hi,
my advice would be the following:
for "nodes" use either a "full"
minimal centos or fedora and install ovirt.org repo on top of that.
then everything works.
the "node.isos" provided by ovirt are in pre-alpha state to be honest.
sure you still have to disable selinux
(or better configure it correctly).
But you have no problems with configurations which are not persisted and as a bonus you
can install $your_favourite_tool on the node, such as tcpdump nmap etc. for debugging.
Again: I would strongly advise against useing the node.isos from ovirt.org at the moment.
There is just too much stuff not working or bugged, even simple things like network
configuration.

Thanks, Joop, for the node platform best practices. I did turn selinux from
"enforcing" to "permissive", and then when I tried to ping the engine
by
fqdn, I saw that DNS lookups were failing (even tho resolv.conf looked
correct.) Did a 'yum remove NetworkManager" and then fixed the
/etc/sysconfig/network-scripts/ifcfg-<nic>, and then after a reboot, I can
now see the info for the node in the WUI on the manager, although the status
for the node is still "Non Operational".
Where can I find the node install log (on the engine or the node, and name?)
(Sorry for noob status, but I am a quick learner ;)
Thanks,
Will

Hi all, ready for a story? (well, more of a rant, but hopefully it will be a

Had one of the groups come to me at work this week and request a OpenStack
setup. When I sat down and discussed their needs, it turns out that they
really only need a multi-hypervisor setup where they can spin up VMs for
their research projects. The VMs should be fairly long-lived, and will have
persistent storage. Their other request is that the storage should be local
on the hypervisor nodes (they plan to use Intel servers with 8-10 2TB drives
for VM storage on each node.) They desire this in order to keep the VM I/O
local - they do not have a SAN of any sort anyhow, and they do not care
about live migration, etc
@Will
If the installation ends, either with or without error, it will give you a
log location. Upload the log to a paste.bin and mail the link.
@Gabi,
There should be more info in either the vdsm.log on the SPM server or in the
engine.log on the engine server, see above for lettings us know what the
error is.
Having installed oVirt, probably dozens of times, I have some guidelines:
- temporarily disable firewalld/iptables (if all works, enable should still
work, scripts with rules are generated and location is given)
- make selinux permissive either via setenforce 0 (until next boot) or via
/etc/selinux/config ( survives reboots), dont disable it!
- make sure fqdn work in both directions between engine and host(s) (either
using /etc/hosts or DNS)
- make sure NetworkManager is disabled and network enabled

Non-operational means it's connected, but missing a cluster resource (can't
access a storage domain, or misses one of the network definitions the

go to the "Network Interface" sub-tab of that node and click the "Setup
Host Networks" button.
In the dialog that has opened, attach the 'ovirtmgmt' network from the
right-hand side of the dialog to one of your node's NICs on the left-hand
side by dragging that network onto the NIC.
click OK.
after a short while, your Host should become 'Up'.

Aha!
"Host <hostname> does not comply with the cluster Default networks, the
following networks are missing on host: 'ovirtmgmt' "
What must I do to correct this? I do not remember reading about having to do
something like this in the docs... Also, the node is on a different network
that the engine, not sure if this matters or not (the two network do have
connectivity to each other thru a router.)

Hi Will,
this should work out of the box.
would help if you can open a bug on this not happening so it will be
verified it does work out of the box.

OK, I will open a bug; trying now to bring up the node using CentOS 6.5
minimal, will keep good notes this time on what I have to do to get it
connected to the engine.

Did you disable selinux on nodes? 'cause that's what is causing SSh
connection closing
My setup:
1 engine on vmware - fedora 19, up-to-date

Hey Will,
that was surely a bad start and we know about the state of Node.
Please take a look at this email
http://lists.ovirt.org/pipermail/node-devel/2014-January/000581.html
to see where you can find a draft image which should address some bugs.

Thanks for reading, and any clues on getting a node up and running
gratefully accepted...
I have had success setting up CentOS 6.5 minimal in nodes, configuring
network, and then adding the node through the management interface - the
Engine takes care of installing & configuring the nodes.
Have you tried this?
Incidentally, you can also have Node images deployed via PXE boot (this
seems orthogonal to your issue, though): http://www.ovirt.org/Node_PXE
Cheers,
Dave.

What/where is the proper RPM for this platform?
That was true until during the oVirt 3.2 release cycle, but we have had
an EL6 Node for a while.
oVirt Node is a stripped down OS image - installing the Node packages on
a minimal EL6 install has also worked since the 3.2 series.
Cheers,
Dave.

oVirt Node is a stripped down OS image - installing the Node packages on
a minimal EL6 install has also worked since the 3.2 series.
just to clarify - there are two types of hosts:
- ovirt-node - stripped down, ESXi like. some workflows of deploying
and updating it are simpler as its image based
- normal linux - just configure the yum repos, and ovirt-engine should
configure everything else.
both types have fedora and .el6 support, and an ubuntu for 'normal
linux' type is making progress as well.
(and yes, it seems the ovirt-node one for 3.3 required a much needed set
of fixes)
Thanks,
Itamar
