When choosing a virtualization technology, you should make a decision based on your specific needs. Here are some considerations to help you choose the right virtualization technology for your Hong Kong server.

1. The operating system that needs to be run

If you need to run a variety of different operating systems on the virtual machine, such as Linux, Windows and FreeBSD, etc., then KVM may be a better choice. Because KVM can support various operating systems, and Hyper-V can only run on the Windows operating system, and the virtual machine must also be Windows or Linux.

2. Performance

If you need to run high-performance applications on virtual machines, such as databases and web servers, then KVM may be a better choice. This is because KVM is based on hardware-assisted virtualization technology, which can directly access the virtualization extension of the CPU to improve performance. In comparison, Hyper-V generally has lower performance than KVM.

3. Management function

If you need advanced management features, such as Live Migration and Cluster Shared Volumes, then Hyper-V may be a better choice. Hyper-V provides some advanced management features that can help administrators better manage virtual machines. In contrast, KVM has relatively few management functions, but it can be integrated with other open source tools, such as Libvirt and oVirt.

4. Cost

If your budget is limited, then KVM may be a better choice. Because KVM is an open source virtualization technology, no additional license fees are required. In contrast, Hyper-V is a commercial virtualization technology that requires high license fees.

Taking the above factors into consideration, if you need to run a variety of different operating systems on the virtual machine and have high performance requirements, then KVM may be a better choice. If you need advanced management features and can afford high license fees, Hyper-V may be a better choice.
