Reproduction steps are in network configuration alone. After installing
Engine, i have to set up network to the config listed here:
http://styk.tv/wp-content/uploads/2014/01/oVirtHosted1_almost_working.png.
Unfortunately can't rely on engine-vdsm duo to help out.

Anything above the host line on the diagram is physical setup and is the
only configuration that doesn't disconnect me from the net.  Only thing
missing on the diagram is ifcfg-eth0 has also HWADDR attribute with MAC
address of physical eth0 device.

Once this survives service network restart I can proceed to VDSM install
and then its straight forwardthat is until I'm trying to SYNC ovirtmgmt
on host inside. I should mention after ovirt engine is working I destroy
default cluster and create new local one.

Obviously I cannot access logs since access to host is no longer but entire
setup is scripted including provisioning so I can easily rebuild entire
setup within 15 or so minutes by running a script. Anyone who would like to
benefit from my findings can use this script and gain access to my host and
learn with me on how to overcome this.

Script will provision the host (fresh os install), log in, get the files:
ifcfg-eth0, ifcfg-ovirtmgmt, ifcfg-ovirtmgmt-range0, ovrit_answers and
route-ovirtmgmt, then install epel 6-8, install pgp, localinstall
ovirt-el6.10-1. install bridge-utils, upgrade, set hostname, then after
reboot ssh alive, set local data,images,iso folders, install ovrit-engine,
set ipv4 forwarding and proxy_arp=1, restart-network, and run engine-setup
with ovirt_answers including cli and stop iptables as engine and vdsm rules
still prevent connection if on. that's it. working system in 15 mins

still to do is engine-api calls to create local cluster, join engine with
vdsm local and setup private network with pfSense instance as
router/nat/dhcp for 10.0.0.0/24

Re: [Users] vlan on mgmt network

[Peter Styk]

So I got ovirtmgmt VM ticked off. Had to remove it from all VM's then tried
to add new Logical network to eth0 by drag & drop but refused since
ovirtmgmt was out of sync. So I synced it. and that's how I lost access
to my hosted remote system. End of story. So that's it I guess, automated
install doesn't work (during switch network goes dead and doesn't come back
remote access is lost) so I found manual way that works. But then I need to
sync it to get my ovirtmgmt not to be a VM network. And even if its not to
get another network on the interface i need to sync it.

I will keep trying, Thanks for the tips.
P.

[Users] Networking. Hosted Setup. All in One Host. Hetzner

[Peter Styk]

Greetings,

I'm writing here as to share some of my findings about hosting with
Hetzner. All in one setups on single remote host can be tricky. Provider
mounted an extra /29 subnet to the main host but none is routed by default
and host has to become router itself. At the same time single mistake in
bridging configuration and lost access results in need for re-bootstrap.
It's still tempting to try and with many trials I eventually got to see
guests talking to the net.

Scenario 1: Working. Package bridge-utils, oVirt engine, setup bridge,
VDSM, add host to engine, add routing to host routing table. Networking by
trial and error. Still something is not right. Occasionally on ping out I'm
getting "Redirect Host (New nexthop" messages.
http://styk.tv/wp-content/uploads/2014/01/oVirtHosted1_almost_working.png

Scenario 2: Dreaming. Private network with private router/dhcp/nat. Private
10.0.0.0/24 network. No problems with routing as gateway 10.0.0.1 would be
on the same subnet. Thought of using pfSense but can't seem to bring up an
instance with two network cards on two different networks. I thought this
would be easy. Go to Networks, click create new network, type private, save
ok. then go to new instance. point at iso, attach two network cards. save
ok. Launch "Host did not satisfy internal filter Network" No idea what that
is. Maybe I don't understand how this works. I even tried removing
ovirtmgmt network and leaving private network by itself. Tried with all 3
network card types (rtl8139/e1000/VirtIO)
http://styk.tv/wp-content/uploads/2014/01/oVirtHosted2_preferred.png

Either way if you have a minute or two please take a look at both attached
diagrams. Deliberately making it difficult by forcing all elements on
single box in hosted environment.

Maybe there is a way to have this all installed with Neutron or vSwitch on
the same box or is that pushing it?

Regards,
Peter

Re: [Users] Video from NetApp event?

[Peter Styk]

Dave,

If you expose raw footage for me on a server somewhere, I can spend time to
re-edit, with logos, sound logos, color correction and overall make it
compact and upload so its embeddable. As to actual recording I'm exactly
9570km from NetApp HQ.

[Users] Video from NetApp event?

Are there any plans to shoot some video at the NetApp event? Would be
really cool to embed some youtubes on the wiki later on.

[Users] What is the new home for /Wp-content/uploads missing after website migration?

[Peter Styk]

To whom it may concern:

Great work on website but please return back the PDF's from the old site
upload directory. Someone took the time to make those. Let's keep them
visible. Just couple of examples are:

http://www.ovirt.org/Wp-content/uploads/2011/11/Quantum_Ovirt_discussion.pdf
http://www.ovirt.org/Wp-content/uploads/2011/11/ovirt-vdsm.pdf

Hat-Droids on the IRC mentioned this might be due to "Wp-content" being
capitalized but either way its not wordpress anymore so what is the new
home for these docs? Perhaps consider permanent 301's as I'm sure these are
linked to many, many blogs, posts and other sites.

roger-roger,

[Users] How to attach virtualized Gluster cluster?

[Peter Styk]

Any chance there is a way to get this to work?

 2 x F16 nodes bare metal
 engine and gluster 4 node virtualized in vmware esxi

engine ok
2x node ok
gluster stand alone setup ok

problem:
Can't attach my stand-alone gluster cluster. Since I'm not using
virtualized gluster bricks to run virtual machines why can't I use it as
storage only?

intuition takes me here:
Cluster #1 [Bare_Metal] Enable Ovirt Service [yes] & Enable Gluster Service
[no]
[shows Hosts and VMs]

Cluster #2 [Virtualized] Enable Ovirt Service [no] & Enable Gluster Service
[yes]
[shows Hosts and Volumes]

Have tried this several Times as full gluster working setup, empty nodes
and oVirt agent nodes. No luck.

Any pointers would be appreciated.

Best,
Peter






Any indication or pointer on how to mount gluster cluster as the only
storage for ovirt would be of great help.
