When transferring a virtual client from one computer to another, which of the following MUST be checked for compatibility on the host?

The correct answer is C. Processors. Virtual machines rely on the host computer's CPU to execute instructions. The destination host's processor must support the same virtualization instruction set extensions (such as Intel VT-x or AMD-V) and, critically, must be compatible with the virtual machine's CPU…

Explanation

Virtual machines rely on the host computer's CPU to execute instructions. The destination host's processor must support the same virtualization instruction set extensions (such as Intel VT-x or AMD-V) and, critically, must be compatible with the virtual machine's CPU configuration. If the new host has a processor with a different architecture or lacks the required virtualization extensions, the VM may fail to start, crash, or behave unpredictably. This is especially important for live migrations. IP addressing methods (A) are a network-layer concern managed within the VM's OS and are not a hardware compatibility issue. Hard drive connection types (B) and rotation speeds (D) are physical host hardware details that are abstracted away by the hypervisor - VMs interact with virtual disks, not the physical drives directly.
