SWAP | 4 GB + | Paging partition for the Linux operating system(Swap memory is been used by virtual servers if there is shortage of real memory) |

Ports
Virtualizor uses ports from 4081 - 4085.
If there is any firewall restricting this, you will need to allow these ports.
TroubleShoot
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.
NAT Pool is not supported for Proxmox.
Input correct Proxmox Server Name and password in Configuration->Slave settings before trying to create vps/add storage.
You can find Proxmox Server Name in pvesh get nodes command output on your server
Cant open http://IP-Address:4084
Please check if your iptables firewall is running You can disable it with the following command :
root> service iptables stop
Error : The storage doesn't exist
If you get this error while adding Storage, please execute the following command :
root> vgchange -ay
Above command should fix the issue.
