Guest file system behavior for type-2 hypervisor-based virtualization in VMware Workstation

This paper presents a comparison of different guest file systems on the specific hosted hypervisor. Chosen hypervisor was the VMware Workstation 15.1 and used file systems were XFS, Btrfs and ext4. To receive the most realistic results we decided to set identical virtual machines (VM) for all measurements: first with a single VM and latter with two VM running at the same time. The host operating system (OS) was Windows 10 and guest OS Centos 7.9. To analyze expected behavior from our hypothesis we have used Filebench measuring tool for getting test results.
