This patch adds support for virtio-fs shared file system that lets virtual machines access a directory tree on the host. To run xfstests on it, first, start virtiofsd daemon in host: ./virtiofsd -o vhost_user_socket=/tmp/vhostqemu0 -o source=$DIR0 -o cache=always ./virtiofsd -o vhost_user_socket=/tmp/vhostqemu1 -o source=$DIR1 -o cache=always second, launch QEMU with: -chardev socket,id=char0,path=/tmp/vhostqemu0 -device vhost-user-fs-pci,queue-size=1024,chardev=char0,tag=myfs0 -chardev socket,id=char1,path=/tmp/vhostqemu1 -device vhost-user-fs-pci,queue-size=1024,chardev=char1,tag=myfs1 -m 8G -object memory-backend-file,id=mem,size=8G,mem-path=/dev/shm,share=on -numa node,memdev=mem then, inside the VM run xfstests with: export TEST_DEV=myfs0 export TEST_DIR=$TESTDIR export SCRATCH_DEV=myfs1 export SCRATCH_MNT=$SCRATCHMNT export MOUNT_OPTIONS="" export TEST_FS_MOUNT_OPTS="" Cc: Dr. David Alan Gilbert <dgilbert@redhat.com> Signed-off-by: Misono Tomohiro <misono.tomohiro@fujitsu.com> Signed-off-by: QI Fuli <qi.fuli@fujitsu.com> Reviewed-by: Eryu Guan <guaneryu@gmail.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
