I’m trying to get NS7 working on a KVM VPS where I previously had NS6.8 working without a problem, but the system breaks in the first software update. I can Install and reach the server at first; I go to the Software centre and it notifies me of the many updates. I go through the update process and at the end of it the server becomes unreachable.
When rebooted, I notice that the update installed a new core that replaced the original NS7 as default. Choosing the older centos option, the system boots without errors but the system is still unreachable either on the web panel or by ssh.
I log in through VNC and issue a db network show which tells me that the ens3 device is misconfigured (no gateway, DHCP, no net mask… I edit the relevant ifcfg-ens3 file and restart network service but the server is still unreachable.
I have now tried this procedure 3 times and every time i end up with a dead server after the initial software update.
Is there any proper way to apply the updates without breaking the server?
