Create Virtual Machines

Create access gateway virtual machines on the cloud platform as needed, according to the preliminary deployment plan.

1. Image Preparation

It is recommended to use the pre-built images from the official version release directory:

  • Image Name: ubuntu-22.04.5-live-server-amd64-20251201.qcow2

2. Key Configuration Parameters

When creating virtual machine instances on the cloud platform, please be sure to manually verify the following underlying configuration parameters:

  • Boot Mode: uefi
  • Chipset: q35

On the OpenStack platform, when uploading images, modify the values of the hw_firmware_type and hw_machine_type attributes:

hw_firmware_type = uefi
hw_machine_type = q35
  • Initial O&M Account: user1 (Please consult vendor technical support for the login password)

3. Resource and Disk Allocation

  • Compute Resources: Please allocate CPU and memory specifications according to the actual business concurrency requirements, as determined in the Deployment Planning chapter.
  • Disk Space: The system disk capacity is recommended to remain at the image's default of 100 GB, with no need for additional data disk mounting.

4. Network and Port Mapping

After the virtual machine is created, please perform public network port mapping:

  1. Public IP Address Allocation: Allocate an independent public IP address for each access gateway virtual machine and configure sufficient bandwidth for this public IP as planned.

  2. UDP Port Whitelisting: Ensure that public network mapping and inbound policies for the following ports are in effect:

    • UDP: 901, 902, 903
    • UDP: 5000
