Zorluk: KolayVirtual Machine Resource Requirements and Hardware Support

A system administrator is configuring a hypervisor host that will run 4 identical virtual machines. Each virtual machine requires 4 GB of RAM to function properly. Additionally, the host hypervisor requires a minimum of 4 GB of dedicated host RAM for its own operation. What is the minimum total amount of host RAM, in gigabytes (GB), required to support this configuration?

Cevap: 20 GB

Cevap

The minimum total host RAM required is 20 GB.

The total host memory calculation must include both the RAM allocated to all guest virtual machines (

4 \times 4 \text{ GB} = 16 \text{ GB}

) and the memory reserved for the host OS/hypervisor (

4 \text{ GB}

), resulting in a total of

20 \text{ GB}

.

Adım Adım Çözüm

1

Calculate total memory required for guest virtual machines

16 GB

Multiplying the 4 virtual machines by 4 GB of RAM per machine yields 16 GB total for guest workloads.

2

Add host hypervisor RAM overhead requirement

20 GB

The hypervisor itself requires 4 GB of system RAM to manage system resources and prevent host memory swapping.
