- Disable CentOS Firewall on OSTemplate
- Enable root User on CentOS OSTemplate
- Install HC Hyper-V components on CentOS OSTemplate
- Install Vmware tools on CentOS OSTemplate
- Install net-tools package
- HC Panel Level Configurations for CentOS OSTemplates
All these steps are explained in detail below in this kb article.
Disable CentOS Firewall on OSTemplate : CentOS 7 Firewall should be disabled on OSTemplate. To disable it, follow the steps given below :
- First, stop the FirewallD service using command: sudo systemctl stop firewalld
