FS Device
Fields§
§socket: Option<String>
the UDS path to a vhost-user socket. If this flag is set, –fd cannot be specified.
fd: Option<i32>
file descriptor of a connected vhost-user socket. If this flag is set, –socket cannot be specified.
tag: String
the virtio-fs tag
path to a directory to share
uid_map: Option<String>
uid map to use
gid_map: Option<String>
gid map to use
cfg: Option<Config>
colon-separated options for configuring a directory to be
shared with the VM through virtio-fs. The format is the same as
crosvm run --shared-dir
flag except only the keys related to virtio-fs
are valid here.
uid: u32
uid of the device process in the new user namespace created by minijail. These two options (uid/gid) are useful when the crosvm process cannot get CAP_SETGID/CAP_SETUID but an identity mapping of the current user/group between the VM and the host is required. Say the current user and the crosvm process has uid 5000, a user can use “uid=5000” and “uidmap=5000 5000 1” such that files owned by user 5000 still appear to be owned by user 5000 in the VM. These 2 options are useful only when there is 1 user in the VM accessing shared files. If multiple users want to access the shared file, gid/uid options are useless. It’d be better to create a new user namespace and give CAP_SETUID/CAP_SETGID to the crosvm. Default: 0.
gid: u32
gid of the device process in the new user namespace created by minijail. Default: 0.
disable_sandbox: bool
disable-sandbox controls whether vhost-user-fs device uses minijail sandbox. By default, it is false, the vhost-user-fs will enter new mnt/user/pid/net namespace. If the this option is true, the vhost-user-fs device only create a new mount namespace and run without seccomp filter. Default: false.
