File system performance for type-1 hypervisors on the Xen and VMware ESXi

This paper presents results obtained for the performance comparison of two type 1 hypervisors, ESXi 6.5 and Xen 8.0. We tested their performance through file system testing procedures using software Filebench, which is a benchmark for file and storage systems evaluation. Both analyzed hypervisors were tested while keeping equal software and hardware conditions. Centos 8.5 is chosen as the guest operating system, and it was installed on the generated virtual machines. To obtain valid results, the hypervisor performances are compared for systems with one, two, and three virtual machines. Initially, we defined the mathematical modeling of the workloads, set up hypervisor environment and hypotheses related to expected behavior, and later confirmed with the obtained results.
