An IT specialist is configuring a host system for virtualization. The server has an 8-core CPU and 32 GB of RAM. Each virtual machine is configured to use two CPU cores and 4 GB of RAM to run a database application that requires significant processing power. Assuming the specialist does not want to over-allocate either CPU cores or RAM, what is the maximum number of these virtual machines that can run simultaneously?
To avoid overallocation, the combined demands of all VMs must not exceed the physical resources of the host.
CPU limit: 8 physical cores ÷ 2 cores per VM = 4 VMs.
RAM limit: 32 GB ÷ 4 GB per VM = 8 VMs.
Because CPU reaches its limit first, the host can support up to four VMs without exceeding either CPU or memory capacity. Running a fifth VM would require 10 CPU cores, which the host does not have, so that would constitute overallocation.
