Comment 4 Fabian Deutsch 2012-09-27 14:45:10 UTC
The following patch fixes this problem:
http://gerrit.ovirt.org/#/c/8247/

Tested as follows:
1. Install fresh rhevh
2. Apply patch
3. Login and enable a NIC with static IP
4. Remove first NTP server, leave just the second
5. Select <Apply>
= Netwok page reappears and second NTP server appears as first.

Also fixed for DNS.

Comment 7 haiyang,dong 2012-11-02 10:28:39 UTC

Steps:
1. Install  rhevh
2. Login and enable a NIC with static IP
4. Remove first NTP server, leave just the second
