| Summary: | A hypervisor is a hardware virtualization technique that allows
multiple guest operating systems to run on a single host machine at the same
time. Each Virtual Machine (VM) or known as guest operating system emulates
all interfaces and resources of a real computer system. Virtualization is beneficial
as one of the educational tools to facilitate students’ hands-on experiences
and research activities. However, the performance of VM needs to be taken into
consideration. We investigate the performance of a set of VMs using Oracle
VirtualBox on several host machines, each of which has its own system specifications.
We observe the resource utilization of each host machine in terms of
its CPU utilization, CPU speed as well as memory usage. Experimental results
show that the CPU utilization averages are 51.78%, 60.7% and 62.57% for cases
before memory allocation, 1/2 of memory capacity and 2/3 of memory capacity,
respectively. It is indicate that the utilization of a host processor is directly
proportional to the memory capacity assigned for a virtual machine. |
