2 Licenses for High Availability - Host 1 detects 1 license 2 servers

I currently have two active Virtualmin licenses, one per host, as part of a basic high-availability setup.

  • Host 1 has two IPs:
    • One public dual-stack IP
    • One NATed IP from the management firewall
  • Host 2 has a single public dual-stack IP

Each host has its own license. Host 2 works fine, but Host 1 reports that its license is being used on two servers. The only recent change is that Host 1 was upgraded (migrated and added more capacity) from RHEL 9 to Ubuntu 24.04, while keeping the same public IP and MAC address mapping.

From my side, this is still a single host with a single license, but Virtualmin seems to detect it as two separate systems.

Is there a supported way to combine multiple licenses into a single multi-server or HA-style license pool? I am fine paying for additional capacity, but I would like to avoid license conflict warnings in a redundant setup.

Thanks in advance, the radio sounds really good :slight_smile:

Sounds like a bug in our license code. It shouldn’t be detecting host 1 as two servers. Though sometimes it can detect that kind of thing if the network configuration changed after install (which should clear on its own after a day or so, if that’s the case).

If the network looked exactly like the current configuration and from the beginning the license was detected as running on more than one machine, it is a bug in our code. If networking changed after installation, then it’s just a side effect of changing system ID and it’ll resolve itself.

No, we used to but it proved too difficult to track and manage, as we don’t have any information about your systems, other than IP and an anonymized system ID. But, your case doesn’t seem like it would benefit from that…we just need to make sure we’re detecting one system correctly and not double-counting it.

Okay, I’ll give it a day or two to clear itself. If still goes on, I’ll chime in, again.

Thanks again!
