I logged in to my server from off-site today and got this message. I have two ip addresses on 192.168.0. One is the in-service (old, small, slow) server another is my office router. On the router is 192.168.1.16 which is a virtual instance of Centos 5.4. I am configuring that machine to replace the existing server, hopefully next week. Yesterday I restored a backup tarball from the existing server to see if all the domains and settings came through ok. As far as I can see they did so this is nice..
So this gives me a simple cutover method, disallow changes for an hour, do a backup on one machine, ftp it to the new machine, restore and then plug the cable into the new box. If I've got mod_proxy configured correctly this ought to give me a seamless transition. But what about the 3 server business? Will that go away when I transition? or is this like the only other similar issue I could find in the support issues? but that was with Cloudmin.
Ideas?
Dave

That message can appear if your system has checked in to our license manager from 3 different IPs in the past few days .. which could be the case during a move. However, if you have changed to the new IP the message will go away by itself in a day or two. And it doesn't actually cause anything in Virtualmin to stop working.

ok, thanks. For clarity, though, I thought the VM Pro lic. was per domain. If I hosted the limit (50 for my lic.) on more than one machine (which I might plausibly want to do) would that be either a lic. violation or generate an error?

Virtualmin Pro is licensed per-server, with domain limits. A Virtualmin license, regardless of size, is limited to one server.
Cloudmin is only restricted by number of VMs (which only makes sense, as Cloudmin only ever runs on one machine, and the VMs can be spread across any number of machines).

The new server I'm preparing has centos 5.4 xen and several domains. Is it the case that you consider each domU to be a server?
I have one site that will do a lot of geodata processing. It would be handy to have that site in its own domain with VMPro running there with only one site. This would allow the site manager to have access to the system analytic tools in VMPro.
Then another domain on the same box would have the rest of the domains (up to the current license max. of 50 - so 49 on one then 1 on the other). This would be pretty handy if I had a requirement for (say) Debian on one domain for a prepackaged site. This was actually the case for my user's domain. He has now worked up a Centos implementation but it would still be simpler administratively for me to let him have his own domain.

Currently, we treat each Xen domU as a separate system for Virtualmin licensing purposes..
