oVirt 4.2 Upgrade
by KSNull Zero
Hello!
Let's assume that we have 2 clusters in a shared Datacenter running version
4.1.
Is it possible to have one cluster running v4.2 and another one running
v4.1 in the same Datacenter (what version will it be, by the way ?) during
transitioning to oVirt 4.2 ?
Thank you.

I don't understand why you would want this unless the ovirtnode itself was =
actually the router, wouldn't you want to only have an IP on the management=
network, and leave the rest of the VLANS blank so they depend on the route=
r to route the traffic:
NIC1 -> ovirt-mgmt - gateway set
NIC2 -> VLAN3, VLAN4, etc...
https://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks/
Viewing or Editing the Gateway for a Logical Network
Users can define the gateway, along with the IP address and subnet mask, fo=
r a logical network. This is necessary when multiple networks exist on a ho=
st and traffic should be routed through the specified network, rather than =
the default gateway.
If multiple networks exist on a host and the gateways are not defined, retu=
rn traffic will be routed through the default gateway, which may not reach =
the intended destination. This would result in users being unable to ping t=
he host.
oVirt handles multiple gateways automatically whenever an interface goes up=
or down.

Is PostgreSQL 9.5 required now as of oVirt 4.2?
by Lacey Powers
Hi All,
I have a setup of oVirt on 4.1 that has been working brilliantly for
over a year, serving the production workloads at my dayjob without
complaint.
Originally, I had set it up with a custom PostgreSQL version, 9.6, from
the PGDG repositories, since the suggested 9.2 was already quite old,
and it allowed me to keep consistent versions of PostgreSQL across all
the infrastructure I have.
Now that I am trying to upgrade to oVirt 4.2, when I run engine-setup
per the directions in the release notes documentation, engine-setup
insists on PostgreSQL 9.5 from Software Collections, comparing the
postgresql versions and then aborting.
I don't see a way to tell it that I have a different running version of
PostgreSQL that's greater than 9.5 already.
Does this mean that no other versions than 9.5 are supported, and I need
to downgrade and use the Software Collections version exclusively?
Or is there a custom setting that I am missing that will enable me to
continue using the 9.6 install I already have.
Thank you for your time.
Best,
Lacey

I wiped the machine and tried again with no luck. Does anybody know what I am doing wrong?

ONN v4.2.3 Hosted Engine Deployment - Auto addition of Gluster Hosts
by glenn.farmer＠netfortris.com
The new Ovirt Node installation script in v4.2.3 automatically adds the gluster hosts after initial hosted engine setup. This caused major problems as I had used different FQDNs on a different VLAN to initially setup my gluster nodes [to isolate storage traffic] - but then put them onto the "ovirtmgmt" network. Because they were gluster nodes - I could not remove them from the ovirtmgmt network to re-install on the proper management VLAN.
I recommend removing the auto-installation of the other gluster nodes - or at least provide an option to decline the automatic addition of the other nodes.

unable to upgrade Centos 7.5 due to ovirt package dependencies

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
Would like to avoid using the --skip-broken option. Does the dependency for
the various storaged packages need to be updated to instead require udisks2?
Thanks.
