  1. Click Manage Computers
  2. Select the Add Multiple Computers radio button
  3. Click Submit
  4. Fill in the following:
    • Hostname - the hostnames of all the computers must have a numerical part that is sequential, use a % as a placeholder where that part would be
    • Start value - the first number of the numerical part of the hostname
    • End value - the last number of the numerical part of the hostname
    • Start IP Address - if using static public addresses, the IP addresses must be sequential; enter the first address here; if using DHCP, just enter something like 1.1.1.1
    • End IP address - the last IP address of the sequence; if using DHCP, you'll need to enter something that would work out to the last address relative to Start IP Address (i.e. if adding 3 computers, use 1.1.1.1 for start and 1.1.1.3 for end)

    • Type - virtualmachine
    • Public IP Address
    • Private IP Address
    • Public MAC Address
    • Private MAC Address
      Note

      For VMware virtual machines, the MAC addresses you choose must be in the range 00:50:56:00:00:00 -00:50:56:3F:FF:FF.
      Pay special attention to the upper bound of this range. 00:50:56:40:00:00 - 00:50:56:FF:FF:FF are NOT valid VMware virtual machines.

    • End Public IP address - the last Public IP address of the sequence; if using DHCP, you'll need to enter something that would work out to the last address relative to Start IP Address (i.e. if adding 3 computers, use 1.1.1.1 for start and 1.1.1.3 for end)
    • Start private Private IP Address - similar to Start Public IP Address, but for the private side
    • End private Private IP Address - similar to the End Public IP Address but for the private side
    • Start MAC Address - if mac addresses are sequential, with the first one being the private MAC address for the first computer, the second one being the public MAC address for the first computer, the third one being the private MAC address of the second computer, etc, you can enter the first one here and then have the option of generating data to add to your dhcpd.conf file later in the processfrom the Computer Utilities page.

  7. Click Confirm Computers
  8. Click SubmitIf you filled in the private address fields and the Start MAC Address, you can now enter the private IP address of the management node that will be handling these virtual machines to generate information to add to your dhcpd.conf file.

Assign a VM to a Virtual Host

  1. Click Virtual Hosts
  2. On the VM Hosts tab, select the virtual host server added previously.
  3. Click Configure Host, You should see VM limit set to a number along with the vm profile, two columns of VM's assigned to host and Unassigned VMs.
  4. Adjust the VM limit to the desired number of vms you would like to run on this host. Warning please
    Note

    Please consult your hypervisor documentation for the recommended number of virtual machines to run concurrently for your virtual server configuration.

  5. Select the virtual machine nodes from the Unassigned VMs: column. 
  6. Click Add.
