virtio-fs allow sharing a directory between the host and the guest.
It require virtiofsd daemon running before starting Qemu.
The wiki [1] recommand to enable the following kernel options:
CONFIG_VIRTIO
CONFIG_VIRTIO_FS
CONFIG_DAX
CONFIG_FS_DAX
CONFIG_DAX_DRIVER
CONFIG_ZONE_DEVICE
But virtio-fs works fine with only VIRTIO_FS.
Note: ZONE_DEVICE can only be enabled on aarch64 since kernel >= 5.7.
ARCH_ENABLE_MEMORY_HOTREMOVE support is missing for previous kernel [2].
