/usr/bin/kvm-device-plugin

Usage of /usr/bin/kvm-device-plugin:
      --config string             Path to the config file.
      --device stringArray        The devices to expose. This flag can be repeated to specify multiple device types.
                                  Multiple paths can be given for each type. Paths can be globs.
                                  Should be provided in the form:
                                  {"name": "<name>", "groups": [(device definitions)], "count": <count>}]}
                                  The device definition can be either a path to a device file or a USB device. You cannot define both in the same group.
                                  For device files, use something like: {"paths": [{"path": "<path-1>", "mountPath": "<mount-path-1>"},{"path": "<path-2>", "mountPath": "<mount-path-2>"}]}
                                  For USB devices, use something like: {"usb": [{"vendor": "1209", "product": "000F"}, {"vendor": "1209", "product": "000F", "serial": "00000001"}]}
                                  For example, to expose serial devices with different names: {"name": "serial", "groups": [{"paths": [{"path": "/dev/ttyUSB*"}]}, {"paths": [{"path": "/dev/ttyACM*"}]}]}
                                  The device flag can specify lists of devices that should be grouped and mounted into a container together as one single meta-device.
                                  For example, to allocate and mount an audio capture device: {"name": "capture", "groups": [{"paths": [{"path": "/dev/snd/pcmC0D0c"}, {"path": "/dev/snd/controlC0"}]}]}
                                  For example, to expose a CH340 serial converter: {"name": "ch340", "groups": [{"usb": [{"vendor": "1a86", "product": "7523"}]}]}
                                  A "count" can be specified to allow a discovered device group to be scheduled multiple times.
                                  For example, to permit allocation of the FUSE device 10 times: {"name": "fuse", "groups": [{"count": 10, "paths": [{"path": "/dev/fuse"}]}]}
                                  Note: if omitted, "count" is assumed to be 1
                                  An "optional" field can be specified for individual paths to allow containers to start even when some devices are missing.
                                  For example, to expose serial devices that may or may not be present: {"name": "serial", "groups": [{"paths": [{"path": "/dev/ttyS0", "optional": true}, {"path": "/dev/ttyUSB0", "optional": true}]}]}
                                  If mountPath is a directory, the device will be mounted to the directory with the name of the device.
                                  For example, to expose the serial devices to the /dev/serial directory: {"name": "serial", "groups": [{"paths": [{"path": "/dev/ttyUSB*", "mountPath": "/dev/serial/"}]}]}
      --domain string             The domain to use when when declaring devices. (default "devic.es")
      --listen string             The address at which to listen for health and metrics. (default ":8080")
      --log-level string          Log level to use. Possible values: all, debug, info, warn, error, none (default "info")
      --plugin-directory string   The directory in which to create plugin sockets. (default "/var/lib/kubelet/device-plugins/")
      --version                   Print version and exit
