thanks, i guess configuring repositories in oVirt Node can only be 
achieved when using Foreman/Satellite integration, is that correct? i've 
just started to use oVirt Node and i'm beginning to realize that things 
are a _little_ bit different compared to a standard linux host.

this brings me to another update related question:
right now oVirt Nodes in my test environment can connect to the internet 
and there recently was an update available which i applied through the 
engine gui, which seemed to finish successfully. i remember wondering 
how i could check what actually changend, there was eg. no kernel change 
IIRC. today i discovered that on both updated hosts /tmp/imgbased.log 
exists and ends in an error:

subprocess.CalledProcessError: Command '['lvcreate', '--thin', 
'--virtualsize', u'8506048512B', '--name', 
'ovirt-node-ng-4.1.1.1-0.20170406.0', u'HostVG/pool00']' returned 
non-zero exit status 5

i have to mention i manually partitioned my oVirt Node host when i 
installed it from the installer ISO (because i want to use software 
raid).
i used partitioning recommendations from 
https://bugzilla.redhat.com/show_bug.cgi?id=1369874 (doubling size 
recommendations).

did my oVirt Node update complete successfully?
how can i check this?
why was there an lvcreate error?

'imgbase layout' says:
ovirt-node-ng-4.1.1.1-0.20170406.0
  +- ovirt-node-ng-4.1.1.1-0.20170406.0+1

kernel version is:
3.10.0-514.10.2.el7.x86_64

thanks a lot again
