A server administrator is planning a hypervisor deployment on a physical host workstation … — CompTIA A+ (Core 1 & Core 2)

A server administrator is planning a hypervisor deployment on a physical host workstation configured with $64\text{ GB}$ of RAM. The host operating system and hypervisor core require a baseline allocation of $8\text{ GB}$ of RAM, and organizational compliance requires reserving an additional $10\%$ of the total physical RAM for hypervisor dynamic overhead and host stability. If each planned guest virtual machine requires $5\text{ GB}$ of dedicated RAM, what is the maximum number of virtual machines that can be concurrently deployed on this host?

Cevap: 9 virtual machines

Cevap

The maximum number of virtual machines that can be hosted concurrently without exceeding host resource limits is 9.

Subtracting both host core memory (

8\text{ GB}

) and dynamic safety overhead (

10\%

64\text{ GB} = 6.4\text{ GB}

) leaves

49.6\text{ GB}

of usable RAM for guest workloads. Dividing

49.6\text{ GB}

5\text{ GB}

per VM yields

9.92

, which rounds down to 9 fully provisioned virtual machines.

Adım Adım Çözüm

Calculate the host dynamic overhead buffer

10\% \times 64\text{ GB} = 6.4\text{ GB}

Hypervisors require reserved memory overhead beyond the base operating system requirements to manage VM states safely.

Calculate total host RAM requirements

8\text{ GB} + 6.4\text{ GB} = 14.4\text{ GB}

Combines base host OS requirement with the mandatory dynamic buffer overhead.

Determine total remaining RAM available for guest virtual machines

64\text{ GB} - 14.4\text{ GB} = 49.6\text{ GB}

Deduct host host dependencies from physical RAM capacity.

Calculate maximum VM count and floor to whole unit

\lfloor 49.6\text{ GB} / 5\text{ GB} \rfloor = \lfloor 9.92 \rfloor = 9

Virtual machines cannot be provisioned partially; total memory allocation must be fully satisfied per instance.
