Hi Everyone, a very happy new user of Virtualmin here after having had a terrible experience with a hosting reseller. I decided to take the time to teach myself what it takes to manage shared hosting in a VPS.
Everything has fallen nicely into place except one critical component of my set-up... backup/restore.
I built the VPS in Google Cloud Platform, and set up a snapshot schedule to take an incremental backup of the entire boot disk (only one disk in this VPS) in the middle of the night each night. Those get created fine, and I'm able to create a new VPS instance using those snapshots. In order to test my backup procedures, I restored my most recent snapshot to the boot disk of a new VM with the exact same specs as my production machine, and edited my client host file to test the functioning of my hosted domains. However, while the VPS is booting up, it never finishes the boot sequence and throws hundreds of errors that all seem to point to not being able to reach the public internet, socket refusals, etc. (entire output of serial console included below).
I have a gut feeling that the machine can't recover unless it's on the configured external IP address - which can't be tested without taking the server offline temporarily. I wanted to check here to see if that is the likely cause before doing so, since I have live sites on there. I'm also worried that a server reboot right now might result in not being able to boot back up (since a snapshot of that same drive can't boot on a new VM).
Any insight from those experts lurking here would be very very appreciated!
Thanks in advance, and excited to join the Virtualmin users community!
