I’m new to Virtualmin and installed it on a virtualized server recently with RHEL 6.4. After having stopped and restarted the service, I shut it down to perform a snapshot in vSphere. When I powered the machine back up, it was displaying a strange hostname: 127. When I ran system-config-network, it threw a few error lines of Python code. What’s more, I opened the DNS configuration to see that the Hostname had been changed to 127.0.0.1 and the search domain had changed to 0.0.1. Finally, when I looked in /etc/hosts, I saw that the entries had gotten garbled with two extra 127.0.0.1 localhost entries in line with the other entries. I removed the extras, and everything worked correctly again.
I’m here for knowledge, however: was it something in Virtualmin that caused this error? Is this something that anyone else out there has seen?
Thanks all in advance for your time and replies.
