Configure webmin + cloudmin on Hetzner dedicated server for KVM. -- 2

The goal of this job is to configure the Cloudmin with KVM virtualization on my dedicated server on hetzner. The server has an /29 subnet assigned, which needs to be configured in the optimal hetzner way, so that all IP from the range will be usable. The goal is to have the KVM virtualization use the IP addresses from the IP range for new virtual machines. The server is also registered as a DNS server, with a FQDN attached and operational. The new VM's should be accessible under subdomains. The webmin + cloudmin is already installed. I assume the configuration will be done via Webmin interface, or directly on the box (ssh). The configuration was already attempted by me, but the IP / subdomain access is not working. The KVM VM status says ping failed in cloudmin. I need assistance with completing the configuration. The configuration will have to be done via by connecting to my machine, from which we will connect to the server, as I do not want to share passwords / give root access. Alternatively I can do the remote hands for you.
