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

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

[root@virtuozzo-30 ~] # prlctl start v1001
Starting the VM…
Failed to start the VM: Operation failed.
Failed to execute the operation. (Details: internal error: qemu unexpectedly closed the monitor: 2020-03-24T11:54:00.088697Z qemu-kvm: -vnc [::1]:10,websocket=5700,password:
Failed to start VNC server: Failed to bind socket: Cannot assign requested address)

If you face above issue while creating VM with VNC enabled, then please try the following steps :

cat /etc/sysctl.conf

It should be as follows :

net.ipv6.conf.all.disable_ipv6 = 0
net.ipv6.conf.default.disable_ipv6 = 0

Once you make the changes and make the content as above, execute the following command to reload the settings:

sysctl -p

Once done, try to start the VM from virtualizor panel.

Cant open http://IP-Address:4084

Please check if your iptables firewall is running You can disable it with the following command if even after allowing ports, the panel is not working :

root> firewall-cmd --zone=public --permanent --add-port=4081-4085/tcp root> /bin/systemctl restart firewalld
