Hi All, As a part of study, i am setting up SUSE Openstack Cloud 6 on Virtual Box. The SUSE administration server installation went fine. Now i need to add a node to it. When a new node is added, it is properly getting PXE booted but failing at NTP synchronization stage. Due to that, the newly booted node is not getting registered with crowbar and not shown in the UI.

Wildly guessing: Despite not being able to get time information via NTP from an outside source, does your admin server’s NTP service think it has time synchronized properly? If not, for example if it does not see a source itself, or if it thinks it has not been up long enough to be stable, I do not know how it will respond to a client. – Good luck.

Whilst the other nodes would boot they wouldn’t then register with the Admin node. Checking the .transcript file on a failed node showed the same time errors you report. Running ntpdate by hand gave more information indicating strata was 16 and thus not suitable. I found that although my VirtualBox host synchronised time my Admin node VM did not. In the end, given I am running VirtualBox on openSUSE Leap, I edited my ntp.conf file to allow the virtual Cloud network I’d created to receive time. ## HTH.

Thanks AB, smflood. @smflood : In the end, given I am running VirtualBox on openSUSE Leap, I edited my ntp.conf file to allow the virtual Cloud network I’d created to receive time. could you please explain it in detail? ntp.conf of host machine? I have HostOnly network where all the VMs were connected. My virtualbox is running on Ubuntu 14.04 ---

My virtualbox is running on > Ubuntu 14.04[/color] So in VirtualBox I created a new host-only network so my SUSE OpenStack Cloud set up is completely private. I set the the IP address to 192.168.124.1 to stick with the documented defaults for SUSE OpenStack Cloud. Given that new nodes will provision and run from 192.168.124.0/24 I edited my /etc/ntp.conf file to add “restrict 192.168.124.0 mask 255.255.255.0” so that they could all synchronise time with my VirtualBox host. That reminds me, I also edited the NTP Barclamp (within the Admin Dashboard) and entered 192.168.124.1 as the External server. I believe this latter step makes sure the nodes know of a suitable server and provided this isn’t a high strata should suffice. ## HTH.

Hi, although your issue has been resolved, I would like to leave a comment. I tested both cloud 5 and 6, and since cloud 6 I had the same problem (no suitable ntp server). In my case it was sufficient to edit the NTP barclamp and add an external NTP server, I didn’t have to edit any config files myself. I don’t know if the ntp server can be the admin server itself, I have an external server available, so I didn’t need to test it. Regards, Eugen ---

Note that in my case it’s not the Admin node that’s acting as the NTP server but my VirtualBox host machine. ## HTH.
