Automatic IP Address Assignment

Automatic IP address assignment can be applied to your Proxmox module, all you need to do is to install 'DHCP' (Dynamic Host Configuration Protocol).
IP addresses will be then automatically requested from a DHCP server. Consequently, the need to manually configure them will be reduced to a minimum.

Important! This option is available only for 'KVM' virtualization type.
Read the below section to learn how to properly install and configure DHCP.

1. First of all, you need to install SSH2 package. You will find precise instructions on how to do that here.
2. Now, you may move to ISC DHCP installation and configuration. Follow the steps below:
  • Install DHCP server package on your Proxmox Node, execute the below command to do so:
sudo apt-get install isc-dhcp-server
  • When ready, configure DHCP server in /etc/dhcp/dhcpd.conf file, run below command to create the file:
sudo nano  /etc/dhcp/dhcpd.conf

Below there is an exemplary content of properly created file: /etc/dhcp/dhcpd.conf.
Take a look at it to see what data should be inside of it:


# Sample /etc/dhcpd.conf
# (add your comments here) 
default-lease-time 600;
max-lease-time 7200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.254;
option domain-name-servers 192.168.1.1, 192.168.1.2;
option domain-name "mydomain.example";
subnet 192.168.1.0 netmask 255.255.255.0 {
#ProxmoxIPv4
host 1 {hardware ethernet 32:62:39:64:33:33;fixed-address 1.1.1.101;}
host 2 {hardware ethernet 32:39:61:31:33:66;fixed-address 1.1.1.243;}
}


  • Key words: #ProxmoxIPv6 #ProxmoxIPv4 suggesting the usage of a specific type of IP address, must be located in the above mentioned file.
Note: Only key word corresponding to a used IP type is required. If you do not use IPv6 then #ProxmoxIPv6 key word is not obligatory.
  • More info about configuring DHCP server can be found here.
3. Turn on ISC DHCP.

To use automatic IP addresses assignment feature, select 'ISC DHCP Server' option in 'Module Settings' under 'KVM Configuration' section.

Tips

1. Operations performed on the virtual servers are not executed immediately. Give your Proxmox Virtual Environment some time for processing the request and execution of operation.
2. Multiple physical Proxmox servers can be joined into one cluster.

When they are joined into one cluster, you can access all of them by connecting to any of them.
While auto-node creates new VM on the server(node) with the most free resources, server-node creates VM on the server(node) which IP address it has (WHMCS's server configuration).

3. OS Templates are not automatically downloaded while configuring a product.
For each virtualization type, templates are downloaded from the Proxmox server depending on which one of them they are generated for.
4. To name the location accordingly to your needs, within the module change the lang into:
$_LANG['node_X']='Your friendly name for node_X';
5. When PAM authentication is used it is necessary to create a client first in order to change the password correctly. Read more about it here.
5. As this module supports templates system, any changes made in the module's templates files will be saved after the upgrade process.

Common Problems

1. When you have problems with connection, check whether your SELinux or firewall does not block ports.
2. Error 'Could not create PVE2_API object' during connecting via noVNC console.

Afterwards, proceed to client's hosting and run 'Change User Role' on it.

Reason: Your certificate is not valid.
Quick Solution: Your client needs to add Proxmox address to certificate exception list.
Best Solution: Configure valid certificate.

4. Blank page during connecting via noVNC console.

Reason: You have not uploaded 'mgnovnc.html' on to the Proxmox server.
Solution: Extract the module and upload 'mgnovnc.html' file located in 'UploadOnProxmoxServer' on all Proxmox servers into '/usr/share/novnc-pve/' folder.

5. Error 'Function "ssh2_connect" does not exist. Please Install SSH2 PECL before you start using the script.'
