Which of the following statements is correct about Huawei FusionCompute virtual machines?

The statement that Huawei FusionCompute virtual machines can communicate with other virtual machines across physical hosts is correct and reflects a fundamental aspect of virtualization technology. In a virtualized environment, multiple virtual machines (VMs) are able to communicate with each other over a network, regardless of their physical location on different hosts. This inter-VM communication capability is critical for distributed applications and services, allowing for flexibility, scaling, and efficient resource utilization across a cloud infrastructure.

Huawei FusionCompute facilitates virtual networking, which enables seamless communication between VMs on different physical servers. This is achieved through virtual switches and network configurations that connect VMs across various hosts in the same virtual data center. In cloud computing environments, this ability to interconnect VMs enhances performance and reliability, enabling more complex architectures without geographical limitations.

The other options are less accurate in the context of FusionCompute's capabilities. For example, virtual machines are designed to be hardware agnostic and can run applications from different sources outside the local host. They are also not limited or optimized for specific physical hardware, as the virtualization layer abstracts physical resources. Additionally, their ability to access the internet is typically not restricted; VMs can indeed have direct internet access provided the appropriate network configurations and security measures are in place.
