If you like running QEMU as a normal user (very common for TCG runs) but you have to run virtiofsd as a root user you run into connection problems. Adding support for an optional --socket-group allows the users to keep using the command line.

Hi In QEMU 8 virtiofsd has been removed in favor of the rust version. Which includes options that are not longer supported, Do you have a view on what should be used going forwards to support virtiofsd in libvirt with qemu 8? The options are showing as depreciated, -o <compat-options>... Options...

...underway to support this device in uboot and I suspect eventually there will be support for OPTEE as well. Any review comments gratefully received as well as discussion about if we should consider creating some new projects for housing these sort of vhost-user backends. Alex Benn?e (19): tools/virtiofsd: add support for --socket-group hw/block: add boilerplate for vhost-user-rpmb device hw/virtio: move virtio-pci.h into shared include space hw/block: add vhost-user-rpmb-pci boilerplate virtio-pci: add notification trace points tools/vhost-user-rpmb: add boilerplate and initial main too...

...ateful and need special attention: * FUSE_INIT - this is pretty easy, we must re-negotiate the same settings as before. * FUSE_LOOKUP -> fuse_inode (inode_map) The session contains a set of inode numbers that have been looked up using FUSE_LOOKUP. They are ephemeral in the current virtiofsd implementation and vary across device reset. Therefore we are unable to restore the same inode numbers upon restore. The solution is persistent inode numbers in virtiofsd. This is also needed to make open_by_handle_at(2) work and probably for live migration. * FUSE_OPEN -> fh...
