If you own a dedicated server hosting service located in Hong Kong and want to make full use of its resources to build multiple Virtual Private Servers (VPS) through virtualization technology, this guide will provide you with detailed steps and code examples for hong kong server rental solution. Suitable for tech personnel and geeks, it lets you easily set up a multi-VPS environment.


Before starting, please ensure your server meets the following conditions:

  • At least a quad-core processor, 16GB of memory.
  • At least 500GB of hard disk storage space.
  • Installed with Ubuntu 20.04 LTS or another Linux distribution.

Server Environment Configuration

First, connect to your server via SSH. Update your system and install necessary software packages:

sudo apt update && sudo apt upgrade -y
sudo apt install -y qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virt-manager

The above commands will install KVM and other virtualization management tools.

Configuring Network Bridging

To allow each VPS to connect to the network, you need to configure network bridging. Create a new bridge file:

sudo nano /etc/netplan/01-netcfg.yaml

Configure your bridge settings in the file and apply the changes.

Creating Virtual Machines

Now, create new virtual machines using virt-manager or command line:

virt-install \
--name myVPS \
--ram 2048 \
--disk path=/var/lib/libvirt/images/myVPS.img,size=20 \
--vcpus 2 \
--os-type linux \
--os-variant ubuntu20.04 \
--network bridge=br0 \
--graphics none \
--console pty,target_type=serial \
--location 'http://archive.ubuntu.com/ubuntu/dists/focal/main/installer-amd64/' \
--extra-args 'console=ttyS0,115200n8 serial'

Change the parameters to meet your specific needs. Each virtual machine can be configured with different resource allocations.

Application of Containerization Technology Docker

In addition to traditional virtual machines, you can also use Docker on your server to create lightweight containers. Install Docker:

sudo apt install docker.io
sudo systemctl start docker
sudo systemctl enable docker

Afterward, you can start creating and managing Docker containers to deploy isolated environments for different projects or services.

Deploying Your First Container

Run a simple container instance with Docker:

docker run hello-world

This will verify that your Docker installation is correct and the container can run properly.

Maintenance and Monitoring

After building a multi-VPS environment, regular maintenance and monitoring are essential. Use the following tools and commands to check the status of your dedicated server and virtual machines:

sudo virsh list --all
sudo docker ps -a

These commands help you monitor the operational status of virtual machines and containers. Regularly update your software to ensure your hong kong server rental solution is secure and reliable.
