After you login, you will see the Admin Panel Dashboard :
Virtualizor uses ports from 4081 - 4085. If there is any firewall restricting this, you will need to allow these ports.
firewall-cmd --zone=public --permanent --add-port=4081-4085/tcp firewall-cmd --zone=public --permanent --add-port=5900-6000/tcp firewall-cmd --reload
NOTE: If you are going to use Webuzo templates for VM creation, please allow ports 2002-2005
NOTE : In all cases please remember to disable SElinux. The Virtualizor installer will try to disable it. For KVM make sure that VT is enabled from bios so VPS can be able to started .
