@isdpcman-0 said in Install mono on XCP-ng: Our RMM tools will run on CentOS but fail to install because they are looking for mono to be on the system. How can I install Mono on an XCP-ng host so we can install our monitoring/management tools? Reply I think it is advised to consider hosts as appliances and not install any external packages (repos are disabled for that purpose, that's probably your issue for installing anything) even in case of clusters of many hosts in a pool, you should deploy same packages on all hosts to expect compliancy between hosts... better use SNMP to monitor you hosts ? or standard installed packages ?

Okay so you deployed XOA, the turnkey VM with XO already installed in it. Are you sure you do not have an IP conflict? Make sure XOA IP is different than the host.

@isdpcman-0 Which version are you running (XOA > Updates)? You can check the logs by connecting to the VM via SSH and then running the command journalctl -u xo-server -f -n 50.

I had a similar issue and found that after changing the static IP directly by editing the network config file inside the XOA VM, things worked fine, but I had to double-check routing afterward. I also ran a quick ip stress test with multiple devices to make sure the new config didn’t cause conflicts or drops on the network. Everything stayed stable after that.
