finalize. If an object holds only virtual references, it can be reclaimed by the garbage collector at any time, just as there are no references. Virtual references must be used in conjunction with the reference queue (Referencequeue). When the garbage collector prepares to reclaim an object, if it finds that it has a virtual reference, it will add the

I/O device allocation, the virtual machine allocates the physical I/O device directly to the virtual machine, and under this model, the driver inside the virtual machine communicates directly with the hardware device, which requires only a small amount, or is not managed by VMM. For system robustness, hardware virtual

: Applications are divided into small stand-alone slices that can be deployed and managed dynamically without the need to run a fat stack on a large, single purpose host. Resource Isolation : Predictable program performance. Maximize Resource Utilization : High performance, high density. Why do I need kubernetes, what does it do? Kubernetes can be implemented to schedule and run containers on a physical cluster or
