+# dedicated_vc
+
+## Overview
+
+Unlike shared virtual cluster sharing whole cluster resource, dedicated vc is bound to specific nodes. 
+"Dedicated" here is bidirectional, in other words, dedicated vc could only use bound nodes, 
+and these node could only be used by this vc. 
+Noticed that dedicated resource will be excluded from shared resource.
+shared_vc_resource = (whole_resource - dedicated_resource) * shared_vc_capacity
+
+This doc introduces how to configure dedicated vc, currently we provide only cmdline tool for it.
+
+## Commands
+
+We provide get, add and remove dedicate vc in the node_maintain.py, working directory is pai/src/tools.
+```bash
+python node_maintain.py dedicated-vc {get,add,remove}
+```
+
+### Get dedicated-vc
+
+```bash
+python node_maintain.py dedicated-vc get -m {master_ip}
+```
+This command output dedicated vc name, nodes and total resource, as below:
+```
+dedicated_1:
+        Nodes:
+        Resource: <CPUs:0.0, Memory:0.0MB, GPUs:0.0>
+dedicated_2:
+        Nodes: 10.0.0.1
+        Resource: <CPUs:24.0, Memory:208896.0MB, GPUs:4.0>
+```
+
+
+### Add dedicated-vc
+
+```bash
+python node_maintain.py dedicated-vc add -m {master_ip} -v {added_vc_name} [-n {added_nodes}]
+```
+This command added {added_nodes} to {added_vc_name}, if {added_vc_name} doesn't exist, it will be created firstly.
+
+Added resource will be subtracted from default vc.
+
+### Remove dedicated-vc
+
+```bash
+python node_maintain.py dedicated-vc remove -m {master_ip} -v {removed_vc_name} [-n {removed_nodes}]
+```
+This command delete {removed_nodes} from {removed_vc_name}, if omit {removed_nodes}, it will delete whole vc.
+
+Deleted resource will be back to default vc
