I'm hitting a bug with 9p when trying to transfer large files. In RHEL at least 9p isn't supported because it's known to have a lot of design flaws; virtiofsd is the supported and recommended way to share files between a host and guest. Add a new hidden `PODMAN_MACHINE_VIRTFS` environment variable that can be set to `virtiofs` to switch to virtiofsd. Signed-off-by: Colin Walters <walters@verbum.org>
