Unable to create cluster, when trying to create nothing happen the GUI just keep showing the cluster creation tab without showing any error.

- Using HVM 24.0 ISO

Scroll up and down and verify all settings.  Some should be in red meaning you made an error somewhere.  Look for little text under the input fields to give you more information about the errors you made.

Showing no error on any tabs at all. Verified all the settings, not the same with previous version if ssh credentials is wrong will show error or if the version is not compatible.

SSH into the manager and do 

sudo tail -f  /var/log/morpheus/morpheus-ui/current

before cluster creation.

Then try to create cluster and check logs above

There must be an error somewhere....

Showing the following error on the logs. I can ping the hosts and ssh the from the HVM manager. I already have a working cluster but using the v8.0.7. Was testing the latest for bulk migration option. Is there any hardening done on the HVM 24.0 iso ?

I think you should contact support for this.

The error is an "unknown error checking host connectivity", so it will lead us to far here to diagnose that.

I would definitely check from the VME manager shell that you can resolve the IPs/hostnames being provided for the new cluster. Ensure that you have connectivity with the credentials you are providing via SSH as well.

May be worth double checking the netplan on the hosts with `netplan get` to make sure static IPs are set, there is a correct default GW, and no duplicate assignment to bonds/nics are set.
