Cloudmin initial setup problems

Hi, i am trying to add another machine to the existing server, this is the error i get when addingXen Host vie Cloudmin control panel.
Setting up Xen host system …

… setup failed! See the error message above.

I dont want to go and change things around so please tell me what can i do to go to the next step


Ok, i added the enp3s0 to boot and it worked, it installed, then i tried to reboot it, then it said secure boot was on and it couldn’t boot, i turned secure boot off, now the system wont load at all, cannot load kernel, now my server is down, help would be appreciated

SYSTEM INFORMATION
OS type and version Ubuntu 20.04
Webmin version 1.994
Cloudmin version 9.6 Pro

I don’t think that Ubuntu 20.04 is supported.

hi,
i reinstalled with 18.04, and now i get this error

I thought Cloudmin was supposed to install this automatically, i have been trying for 3 days now and i get no replies from the techs.

Looking at the install script, I don’t even think that Ubuntu is supported. Your best bet is to use RHEL 7 or similar.

it says on their website 18.04 is supported

Oh, OK. A quick google turns up that this error:

sudo: no tty present and no askpass program specified

is because the script is running sudo without a password.

hi, thats weird, because that is the cloudmin script running and then gives out this message, is there a way around it?

how are you running the cloudmin installer?

i meant when i try and add host system in cloudmin i get this error, and this is 2 days now i am not getting any response from techs

So you have set up a clean Ubuntu 18.04 server and then you have run something like:

wget -O cm-install-pro-50.sh https://cloudmin.virtualmin.com/cgi-bin/cloudmin-debian-install.cgi?serial=123456\&key=yourserial; /bin/sh cm-install-pro-50.sh

Have you sent them a private message?

Hi Paul
i already have cloudmin installed on my main server, i am trying to setup secondary server and install xen on there, as far as i understand you only need cloudmin installed on the main server right?

Yes, you install Cloudmin Pro on one server as the ‘Master’ and Cloudmin GPL on others.

Perhaps this is where you missed a step. You need to install Cloudmin GPL on your secondary servers too.

Is Cloudmin Pro installed on Ubuntu 18.04?

no, its installed on ubuntu 20.04
now i have another problem, since i reinstalled ubuntu on secondary, i cannot get the hostname to work at all.

do i need virtualmin installed on secondary server?

hi, didnt work, got same error, with gpl version installed on the seconondary

The only supported Linux distributions are CentOS 5, Redhat Enterprise 5, Debian 4.0 and Ubuntu 8.04. (for cloudmin GPL)

this is from Webmin website, is this outdated or what?

i installed centos 7, got xen to install, but when try to register it just times out, i dont know what else to do

No

Yes, it is incorrect

So this is as a secondary Cloudmin server?

You have to add the secondary cloudmin server as a physical system:

‘Add System’ → ‘Add Physical System’

Is the secondary cloudmin server on the same network as the primary?

Or are they on different networks?

@Sinisha82,

Curious, any reason why you are using Xen instead of KVM?
