dns ui capture

Description of problem:
 DNS does not reflect the actual conf files settings

 although "/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt"
 include DNS1..N keys, the DNS Web UI for that bridge is empty.


Version-Release number of selected component (if applicable):
 4.2.4.1-0.1.el7

How reproducible:
 100%

Steps to Reproduce:
 1. Go to Network | Networks 
 2. Edit 'ovirtmgmt'
 3. Enable 'DNS Configuration' and add two IPs e.g.: 10.35.28.1 & 8.8.8.8
    and click Ok.
 4. Disable 'DNS Configuration'

Actual results:
 At the host:
 "/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt"
 include DNS1..N keys, see attached screen capture...

 At the UI
 The DNS is disable but there are no IPs
 see attached screen capture...

Expected results:

Comment 1 Dan Kenigsberg 2018-06-06 16:22:56 UTC 
What is the state of /etc/resolve.conf ?
Is Engine updated if you click Refresh Caps after some time?
Comment 2 Roni 2018-06-07 07:17:34 UTC 
/etc/resolve.conf status is the same as:
"/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt", 
meaning it include the two DNSs I added 10.35.28.1 & 8.8.8.8

Note that not refresh and not vdsmd restart fix this issue
Comment 3 Dan Kenigsberg 2018-06-11 10:15:48 UTC 
What is reported from `vdsmcli Host getCapabilitites`? What is reported from Engine's REST API? (I'm trying to check if this is indeed only a UI problem)

`vdsmcli Host getCapabilitites` output
Comment 5 Roni 2018-06-17 10:12:43 UTC 
I didn't see the DNSs at the REST API, do you know about a special URI?
Comment 6 Yaniv Lavi 2018-06-24 07:28:37 UTC 
Removing DNS will only apply to new hosts by design.
