  11. Edit network adapters to connect on proper networks. Make sure that at least one of the adapter connects to the private management network of the setup from which WebPortal access will be granted. Do not press the 'Save' button yet.

  12. Click on 'CPU' to open the details. Set 'Shares' to 'high', enter the maximum number of MHz corresponding to your number of CPU cores in 'Reservation' (See Calculating Reserved CPU) and make sure the 'Unlimited' option is selected. Do not press the 'Save' button yet.

  13. Open the 'Memory' details and check-mark the 'Reserve all guest memory (All locked)' option, set Limit to 'Unlimited' and Shares to 'High'. Do not press the 'Save' button yet.

  17. Once the VM had completely booted, its assigned DHCP IPs will be displayed in General Information -> Networking. Note this IP address to access the Web Portal configuration interface later.

Calculating Reserved CPU MHz

To get the MHz per core, you need to figure out the total number of available MHz that your system has and divide by the total number of cores.

  1. Select 'Host' on the left menu

  2. Take note of the number of cores this system has. (In this example: 12) Also take a look at the 'CAPACITY', but is is not precise down to the MHz (In this example 36.7 GHz)

  3. When editing the VM, in the disk details, expand the 'Reservation' combobox. There should be a number in exact MHz for the maximum capacity of the system (In this example: 36708)

  4. Calculate your VM CPU MHz Reservation requirement
mhz_per_core = total_system_mhz / total_system_cpus (In this example: 3059 = 36708 / 12 )
vm_reserved_mhz = vm_cpus * mhz_per_core (In this example: 12236 = 3059 * 4 )
