Tested on a fresh proxmox-ve_8.4-ALPHA-1.iso install.
Configured a directory mapping and passed it to a Debian VM with the
default settings. Inside the VM I mounted the directory using
`mount -t virtiofs dirid /mnt/path`.
Writing some data to the directory from inside the VM with
`dd if=/dev/urandom of=/mnt/path/bench bs=1M` was decently fast:
190 MB/s

Virtio-fs is a shared file system that enables sharing a directory
between host and guest VMs. It takes advantage of the locality of
virtual machines and the hypervisor to get a higher throughput than
the 9p remote file system protocol.
build-order:
1. cluster
2. guest-common
3. docs
4. qemu-server
5. manager
I did not get virtiofsd to run with run_command without creating
zombie processes after stutdown. So I replaced run_command with exec
for now. Maybe someone can find out why this happens.
v17:
* qemu-server:
* d/control: 'virtiofsd' in Recommends instead of Depends
* added check if virtiofsd is installed
* pve-manager:
* moved directory mapping in its own tab to save vertical space in the
"Resource Mappings" tab - discussed off-list with Dominik
