Hello, just started to work with Cloudmin GPL for kvm, had a few problems - all solved. Problem is (is it something like the validation of some sort, kind of Virtualmin's?) when I press Refresh Status or Refresh Status Fully, I get:
Fully refreshing system status and available packages ..
.. done.
New status is : Virtualmin (51 domains) - Config errors found
Now, can someone be more specific than that, what does it does and what does it mean (I doubt that someone put those links right on top of the first page of Cloudmin for nothing :)? Where can I get info about the errors?
PS: the validation in VIrtualmin says everything is ok, so I think it's not related.
BTW: Here it says "1. Go to Add System -> Add physical system ." http://www.virtualmin.com/documentation/cloudmin/gettingstarted but I can't find anything like that in Cloudmins menu, as i would like to try adding a new machine to the setup? Hope I'm not blinding or something :)
Thanks!
Also there are some really old images in New System Images... pls update them. It seems there are a lot of missing features in Cloudmin GPL, or is something wrong with the documentation as I can't find 90 percent of what you are talking about. So... what is your goal with the GPL edition?
Don't take the name of root in vain...Howdy,
The GPL version of Cloudmin allows you to manage a single server running Xen or KVM based VPS's.
You would need the Pro version in order to manage physical systems, such as what the "Add Physical System" option provides.
I suspect the docs you're reading were written before Cloudmin GPL came to be -- it looks like we need to review the documentation there and make some clarifications.
If you hadn't seen this yet, there's some details on Virtualmin GPL here:
http://www.virtualmin.com/documentation/cloudmin/gpl
TY for your answer andreychek. It is a very limited feature set then, kind of dissapointed, but no matter, it's your software, you decisions. Virtual Server Replication is also out of the question then?
Regarding the errors, any info?
And something else: tried to make my first kvm machine, problem is tried on my Virtualmin Pro production server, and instantly everything gone nuts, domains unreachable, server errors, e-mails from webmin telling me that the domains were down etc, so I had to try and restart the server, during the unfinished creation of the VM, ouch, took about 30mins to restart but he did it :). Deleted the 2 files created (anything else I should check?) and found this in the logs - some kernel errors probabily heavy load related (strange as it didn't seem that big - it's a quadcore Opteron 2379HE, 8GB ram, Velociraptor 10000rpm drives...):

Also... i can't connect to the VM, on the Graphical Console I get a blank page (can't install an operating system from an ISO) and:
If the Java VNC applet does not run or cannot connect, you can use a separate VNC client to connect to 192.168.1.2 port 5901 instead, and login with password xxxxxxxDon't take the name of root in vain...Another error/thingy: how can i get rid of:
Image CentOS 6.0 KVM instance with base OS is already being downloaded.Cause it doesn't download anything, for days...
Don't take the name of root in vain...
