VIRTFS or VirtFS is a linux system process used to help manage the files on your system.
VirtFS is a new paravirtualized filesystem interface designed for improving passthrough technologies in the KVM environment. It is based on the VirtIO framework and uses the 9P protocol.
Why use it?
- virtualization aware filesystem
- offers paravirtualized system services
- simple passthrough for directories from host to guest
- Backward/forward compatibility issues
Virtual Machine Manager integration since version 0.9.1
The /home/virtfs directory contains critical operating system files. If you
remove /home/virtfs, or any directories under /home/virtfs, you will cause
irreparable damage to your operating system. Do not remove /home/virtfs, or any
directories under /home/virtfs, unless you have tested, up-to-date backups.
You should ignore any disk usage warnings you receive that are associated with
the /home/virtfs directory!
