First attempt to install Cloudmin 9.3.kvm Pro on a new CentOS Linux release 7.5.1804 server.
a. Didn't download the "pro" version, this is the GPL version, main screen says "Pro"
No eth0 on this machine confuses Cloudmin installer. Error message "Use the --bridge-interface flag to set the correct interface" isn't really helpful on a brand new install. Probably would have been better to say something like "can't find eth0" would make it easier to figure what you are looking for.
Now that we use "iproute2" type commands instead of brctl, Webmin won't create the bridge for you. (yum install bridge-utils fixed the script error)
Complaints about "no fuser" command on the login screen for Webmin. #yum install psmisc fixed that, but perhaps it should be on the list of stuff to be installed initially?
Cloudmin System Operations - File Manager is the old Java one still.
