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
If you are going to use Webuzo templates for VM creation, please allow ports 2002-2005

Trouble Shoot

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 start.

Not able to start VM

1. If you try to start the VM from command line and got the following error :

[root@virtuozzo-30 ~] # prlctl start v1001
Starting the VM... Failed to start the VM: Operation failed.
Failed to execute the operation. (Details: The name org.fedoraproject.FirewallD1 was not provided by any .service files)

Please start the firewalld service by executing the following command :

root> service firewalld start

Cant open http://IP-Address:4084

Please check if your iptables firewall is running. If it is running as it should because on virtuozzo it is required.
You will need to add the following rule to acceess the panel :

root> iptables -I INPUT_direct -p tcp -m tcp --dport 4081:4085 -j ACCEPT
