Note

After sending the restart request, the hypervisor will choose what it thinks is the best shutdown method. Note that the request may be ignored by the virtual machine. To force restart the virtual machine, please add the force_reboot parameter to the url. If the parameter is equal to true or 1, it will be forced to restart. If it is equal to false or 0 or no parameter, it will still use the above traditional method to restart. The request url to force restart the virtual machine is as follows:

http://<dbc_client_ip>:<dbc_client_port>/api/v1/tasks/restart/<task_id>?force_reboot=true :::

9. Query Virtual Machine Logs

request method：POST

request URL：http://<dbc_client_ip>:<dbc_client_port>/api/v1/tasks/logs/<task_id>?flag=tail&line_num=10

request body：

{
  "peer_nodes_list": [
    //node_id of GPU Node
    "58fb618aa482c41114eb3cfdaefd3ba183172da9e25251449d045043fbd37f45"
  ],
  "additional": {},

  "session_id": "The session_id distributed by the renter",
  "session_id_sign": "session_id_sign distributed by the renter"
}

Tips

The request url for querying virtual machine logs has two parameters. The flag indicates the direction of the query log. If the parameter is equal to tail, the query starts from the end of the log file. If it is equal to head, the query starts from the head of the log file. line_num indicates the number of log lines to be queried. If it exceeds the actual number of lines in the file, the actual number of lines in the file shall prevail. Finally, this request returns up to 1024 bytes, and logs that are out of range are truncated.

Bare Metal Node Operations

To control operations such as switching on and off a bare metal server, you need a CPU server that is on the same network as the bare metal server. Run the bare metal node program of dbc on this CPU server, and then add the relevant information of the bare metal server (IP address and IPMI control information) to the node, and the node will generate a corresponding "node_id" for the bare metal server to join the dbc network, the bare metal server can be rented and controlled by "node_id".

To install dbc bare metal node, please refer to dbc bare metal nodeopen in new window

In the cloud Internet cafe scene, after a GPU machine is connected to the chain in the form of a bare metal server, if you want to obtain an e-sports-level gaming experience, you also need to use a low-latency remote control software based on cloud games- DeepLinkopen in new window.

Correspondingly, to use DeepLink remote control, it is necessary to obtain the device code and device verification code of the DeepLink software running on the GPU machine (hereinafter collectively referred to as DeepLink device information). To this end, we add an interface to query DeepLink device information through the dbc node.

In order to ensure security, it is recommended that the GPU machines in the cloud Internet cafe scene have different device verification codes every time they are powered on, and use the interface for setting DeepLink device information to inform the bare metal node of the dbc of the device information as soon as it is powered on.

In addition, you need to modify http_ip=127.0.0.1 in the configuration file dbc_baremetal_node/conf/core.conf of the bare metal node to http_ip=0.0.0.0, so that the bare metal node can directly accept HTTP requests.

When the GPU machine and the bare metal node of dbc are in the same network, you can directly use the HTTP service of the bare metal node to get/set device information, and the request at this time does not need session_id and session_id_sign parameters. When the renter queries the device information through the HTTP service of the client node, it must have session_id and session_id_sign parameters.
