Class topic

1. Introduction to Compute Virtualization

Computing virtualization uses the hypervisor to separate resources from upper-layer applications. Computing resources (CPU, memory, and I/O) are pooled. Independent VMs (VMs) are built on the hypervisor. Resources of VMs are logically isolated based on their requirements. Obtain resources on demand. Implements logical resource isolation and physical resource sharing, greatly improving resource utilization...(More)


2. FusionCompute Compute Virtualization Management

FusionCompute computing virtualization management includes VM life cycle management, virtual resource management, and VM resource configuration management...(More)


3. Introduction to I/O Virtualization

I/O virtualization can be considered a hardware middleware layer between the system of a server component and various available I/O processing units, allowing multiple guest OSs to reuse limited peripheral resources...(More)


4. Introduction to Memory Virtualization

Memory virtualization refers to centrally managing the physical memory of a PM and dividing the physical memory into multiple virtual memory spaces for multiple VMs uses memory virtualization to share the physical system memory and dynamically allocates memory to VMs...(More)


5. Introduction to CPU Virtualization

FusionCompute compute virtualization uses KVM technology. CPU virtualization of KVM is a CPU-assisted full virtualization solution, which requires the support of CPU virtualization features...(More)
