Browse source 
It has been deprecated since 8.1; remove it and suggest using the 'local' file
system backend driver instead or virtiofsd.

Define a new file system device. Valid options are:
``local``
Accesses to the filesystem are done by QEMU.
``proxy``
Accesses to the filesystem are done by virtfs-proxy-helper(1). This
option is deprecated (since QEMU 8.1) and will be removed in a future
version of QEMU. Use ``local`` instead.
``synth``
Synthetic filesystem, only used by QTests.
