ovirt 3.6 node
by Johan Kooijman
Hi all,
I can't seem to find ovirt 3.6 node ISO. Is there a specific reason for
this? I have the issue with 3.5 (ovirt-node-iso-3.5-0.201502231653.el7.iso)
that I can't do live merge on machines installed with ovirt node.

Fresh install failing (Hosted Engine)
by Jonathan Sherman
I want to extend my lab and am trying an install using the hosted engine,
but the install is failing for me:
References used for install:
https://glennsnead.wordpress.com/2016/02/28/ovirt-3-6-installation/
http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/
Setup:
Minimal install of CentOS Linux release 7.2.1511 (Core)
Using DHCP with static address (tried without DHCP with same issue)
yum upgrade
Installed packages:
yum localinstall -y
http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm
yum install -y ovirt-hosted-engine-setup screen glusterfs-server nfs-utils
vdsm-gluster system-storage-manager mailx
rebooted
Tried hosted-engine --deploy, but it errors out. I followed various logs
and I _think_ it's failing related to vdsm-tool restore-nets. I could use
some guidance on this to help track down what's happening and how to fix.
(Note: I'd very much prefer using the hosted engine vs. another option for
my lab, so I'm willing to put in the time to figure this out. Thanks for
any assistance!)

Remove master storage from data center?
by nicolas＠devels.es
Hi,
We've migrated storage from glusterfs to iSCSI, so now we have 2
storages in our data center. As we've already finished, we want to
remove the gluster storage from our data center (which is the master
storage right now).
We've tried to put it on maintenance but we're getting this error:
2016-03-02 13:02:02,087 ERROR

Does that mean that *all* hosts must be on maintenance to do that?
There's nothing left on the gluster storage right now.
Thanks.

Re: [ovirt-users] Update Self-Hosted-Engine - Right Way?
by Taste-Of-IT
Hello Simon,
i am new with oVirt, but are you sure, that this is the way for the
self-hosted-engine? Because i have no commands with hosted-***. As far
as i understand the engine runs in self-hosted-engine on same host and
therefore there is no way to enter the vm with engine and set it to
maintenance mode.?!
Regards
Taste

some ISO images not recognized
by Stefano Cislaghi
Hello everyone,
I configured a test environment with 2 hosts (centos), hosted engine
and NFS storage for data domain and iso domain.
I noticed that windows 2012 ISOs are marked as "unknown" in iso domain
and##SELECTION_END## therefore I can't attach them to virtual machines.
Maybe something is wrong with my iso? I tried to do a fresh download
with same result. Centos, Fedora and Windows 10 iso are working, so I
think the iso domain is ok.
Did someone else noticed such behaviour? Any solution?
Thanks

Testing openstack inside ovirt environment
by Gianluca Cecchi
Hello,
Up to now I only tested openstack on physical hw.
I would like to make some tests in a virtual environment.
Not considering at the moment cinder and glance integrations provided by
oVirt but full openstack itself.
Are nestedvt and macspoof vdsm hooks the only requirement I should care
about to be able to go?
Also, supposing I go with a preliminar pre-test of openstack in virtual
environment using plain qemu/kvm with virt-manager, it's clear to me how to
enable the nested kvm for the host, but what should be the commands to give
on host side so that the openstack instances will be able to communicate
with the outside world (the commands that in ovirt I presume are run by
the macspoof vdsm hook).
Thanks in advance,
Gianluca

Promiscuous Mode
by Clint Boggio
I am deploying an OpenVPN server in my OVirt environment and I've come to a dead stop with the developer support on a topic related to OVirt configuration.
The developer wants me to put the VM's underlying NIC into promiscuous mode.
I've seen this in a VMware environment and I know what they are asking me to do, and I'm wondering if there is a clear way to do this in my OVirt environment.
I found "port mirroring" but no "promiscuous mode"
Cheers and thank you !

set up of fibre channel storage problem
by Campbell McLeay
Hi,
I've set up a node in a cluster which I would l like to use the
attached fibre channel disks as storage. The ovirt version is 3.6 and
both hosts (engine and node) are running Scientific 7.2. When I select
the fibre channel option in the ovirt manager GUI from the drop down
menu in the storage section, it shows the target disks on the node
host (actually symlinks named as 34 character IDs which I assume are
created by multipathd, which point to the actual device in /dev such
as /dev/dm-3). 'multipath -ll' shows the devices up and running:

When I select those IDs, it says 'The following LUNs are in use' (does
it perhaps mean by multipath?), and to 'Approve operation', which I
do, but it then fails with:
"Error while executing action New SAN Storage Domain: Physical device
initialization failed. Please check that the device is empty and
accessible by the host."
The storage is not mounted and is not being used by any other host.

The tool in this case is "import-to-ovirt", I guess (since they
already run on KVM it must be)?

import-to-ovirt can handle multiple disk images. If the disk images
are part of a single guest, then you should specify them all in one
command line run, ie:
sudo ./import-to-ovirt.pl disk1 disk2 disk3 mountpoint
If the disk images are independent guests then you must run
import-to-ovirt three times.

No, you need to specify it by running import-to-ovirt once per guest.
