I have the following python script that creates an external network, but now after updating ovirt a new option "network port security" exists that is set as enabled by default.
How can i disable the network port security?
networks_service = connection.system_service().networks_service()
# Use the "add" method to create new VM logical network in data center
network = networks_service.add(
description='Network for testing API',
since several days i try to install the hosted engine initially to an iscsi multipath device without success.
Some information on the environment:
- Version 4.3.3
- using two 10gbe interfaces as single bond for the ovirtmgmt interface
- using two 10gbe storage interfaces on each hypervisor for iscsi storage
-- each storage interface is configured without any bonding, etc
-- each storage interface lives in a separate vlan were also the iscsi Portals/target are available, the iscsi portals have 4x10ge interfaces each, (2 in vlan xx and 2 interfaces in vlan yy )
-- so; each storage interface is connected to two iscsi Portals via 4 interfaces
The documentation here is for me unclear:
>Note: To specify more than one iSCSI target, you must enable multipathing before deploying the self-hosted engine. There is also a Multipath >Helper tool that generates a script to install and configure multipath with different options.
This indicates for me that it should be possbile to install the HE directly on the /dev/mapper/mpath device which is availibale when I have prepared the host accordingly before installing the HE (log in to multiple iscsi targets, create proper multipath,conf, etc) - right ?
I login to the two iscsi portals and get in sum 8 pathes, 4 from each interface and iscsi target.
Basically I have then the mpath device on the hypervisor available and i can mount the mpath device and put data on it.
In the cockpit interface the mount can also be activated and is recognized correctly.
multipathd -ll and lsblk looks good. Everything seems to be fine.
But when I run the "hosted-engine" --deploy, the last option while running the assistant is to enter the iscsi data.
So, basically i just want to define my mpath device - when entering the data (ip, port)for the iscsi Portal I can see the 4 pathes of the single hosted Engine target,
and when i choose the path where the "lun" is finally available it fails. I think in general this option is not that what i want to have
here for using the multipath device.
I' m lost - what is the usual way to install the HE on a multipath device ?
Do i have to change the configuration of the storage interfaces or the iscsi network design?
Did I missed something obvious ?
Can I put in my multipath data into the answerfile to get rid of the last step of the assistant ?
Can I use the related ansible role for specify the Mpath device which is available when activating the multipath service ?
Is it not possible in general ?? :

So I updated our environment a bit ago during a scheduled down time from 4.2 to 4.3. Everything went smoothly, but it looks like I forgot to update the Data Center Compatibility (See alert message below). My question is, can I just change the Data Center compatibility to 4.3 while the environment is running without causing issues, or do i need to shutdown all my VM's and put the hosts into maintenance mode? The compatibility version for everything else is already set to 4.3.
"Data Center compatibility version is 4.2, which is lower than latest engine version 4.3. Please upgrade your Data Center to latest version to successfully finish upgrade of your setup"

I just ran yum update on my test cluster and ran into the following issue:
I did notice that the python2-ioprocess is currently installed from the
Repo RPM: ovirt-release43-pre-4.3.6-0.1.rc1.el7.noarch
yum -y upgrade
Error: Package: vdsm-python-4.30.25-1.el7.noarch (ovirt-4.3-pre)
Requires: python-ioprocess >= 1.2.1
Installed: python2-ioprocess-1.1.2-1.el7.x86_64 (@ovirt-4.2)
python-ioprocess = 1.1.2

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

I installed an SSL cert from a public CA (Let's Encrypt) on my engine,
That gets the regular web UI working, but I can't upload an ISO. I
assume that I need to do something with the imageio-proxy service on the
engine, but not sure what... I tried replacing imageio-proxy.cer and
imageio-proxy.key.nopass, but that didn't work.
I'm trying to avoid ever needing to install a special CA cert in

I'm not sure, but I always thought that you need an agent for live migrations.
You can always try installing either qemu-guest-agent or ovirt-guest-agent and check if live migration between hosts is possible.
Have you set the new cluster/dc version ?
