Your question wasn't particularly clear.

The device dictionary is stored on the master and then combined with the devce-type Jinja2 to create a set of YAML instructions which are sent to the worker. Commands within the device dictionary (like power_on_command etc.) do NOT need to be available on the master but MUST be available on the worker.

In addtion,through web admin interface,I had added qemu device, and web devices list can display new qemu device ok. But I did't write above config items to any .jinja2 file. It can work success even without .jinja2 config file,is right?

No, it cannot. The database object exists only for the UI and the scheduler. The Jinja2 configuration is used to create the instructions sent to the worker to actually run the test job. There must be a device-type Jinja2 file and there must be a device dictionary which specifies which device-type jinja2 file to "extend" with any specific values for that device. Typically, QEMU might only need a MAC address.

Hello,

the device dictionary should be store in /etc/lava-server/dispatcher-config/devices/<hostname>.jinja2

For example, if your device is called qemu-01, the device dictionary should be stored at /etc/lava-server/dispatcher-config/devices/qemu-01.jinja2

You don't have to restart any process after a change to a device dictionary.

I am building lava test system and currently add new addvice.
According to document than step of "Adding a dictionary to the first QEMU device",follow config items neet to write to .jianja2 file.
{% extends 'qemu.jinja2' %}
{% set mac_addr = '52:54:00:12:34:59' %}
{% set memory = '1024' %}

Which file is to be writen to above config items ?does its directory path must be at path:/etc/lava-server/dispatcher-config/device-types/?
How to make these items take effect immediatly?which command to use to take effect above config items? the document is not said.
