Hi,
I have installed IPA across 3 nodes. In order to point the ovirt server at
the new IPA/DNS servers and to clean up I ran engine-cleanup aiming to
delte the ovirt setup. However it seems even though I ran this something,
"vdsm?" is still running and controlling the networking.
So down under /etc/sysconfig/network-scripts I see,
=========
/etc/sysconfig/network-scripts
[root@ovirt1 network-scripts]# ls -l
total 256
-rw-rw-r--. 1 root root 130 Nov 1 10:32 ifcfg-enp0s25
-rw-r--r--. 1 root root 254 Sep 16 2015 ifcfg-lo
-rw-rw-r--. 1 root root 252 Nov 1 10:32 ifcfg-ovirtmgmt
8><-----
==========
So my first Q is why when I run engine-cleanup isnt the networking cleaned
up? should I file this as a bugzilla?
After that I can see that ifcfg-ovirtmgmt is still controlling DNS,
==========

[root@ovirt1 network-scripts]# tail ifcfg-ovirtmgmt

So I tried to set,
DNS1=192.168.1.31
DNS2=192.168.1.32
DNS3=192.168.1.33
rebooted and, no I see,
DNS1=192.168.1.240 again
So I also see that the vdsm service is still running,

why after cleaning up is this still active?
Next, I have grep'd under /etc/ and cannot find where its getting its
obsolete network DNS info info from.
So I need to know where this info is stored? so I can edit is via the CLI?
database?
There is no web ui running as engine-cleanup has removed that so I cant
work via the web ui.
Is there anything else I need to manually stop, disable and remove after
running engine-cleanup?
thanks

engine-cleanup only cleans up the engine. It does nothing to the hosts.
I am not aware of a similar "vdsm-cleanup" tool.
In principle, you could have moved your hosts to maintenance and removed them
from the engine. No idea what this would tell vdsm to do wrt to your question.
It definitely would not undo ifcfg-* changes.

If VDSM is running, any network devices it used are owned by it.
Editing manually ifcfg files it owns will result in VDSM restoring them to
their persisted state
in vdsm configuration files.
I guess, you can just uninstall/remove vdsm and continue from there: sudo
yum remove -y vdsm\*

There is automatic restoration for rollback scenarios, but these are
usually overwritten multiple times
for each successful setup. We just save the last good network setup and in
case of failure to a new setup
it is restored back to the good point.
I also do not see to much logic in allowing restoration to the 'before
vdsm' period. The network connections
of the hosts could have been changed from that time.
