# ​Multipass虚拟机配置教程

### **一、查看默认配置**

#### 注意：以下 ubuntu-niulink 是示例虚拟机名称，这个名称随着业务改变而不同

```bash
bash
# 确认目标虚拟机名称及当前状态
multipass list

# 查看CPU核心数（默认2核）
multipass get local.ubuntu-niulink.cpus

# 查看内存容量（默认2G）
multipass get local.ubuntu-niulink.memory

# 查看存储空间（默认64G）
multipass get local.ubuntu-niulink.disk

```

**说明**：默认配置适用于轻量级场景，边缘算力场景需根据硬件资源动态调整。

***

### **​二、动态调整配置**

1. ​**查看虚拟机状态**

   ```bash
   bash
   # 确认目标虚拟机名称及当前状态
   multipass list
   ```

2. ​**停止相关服务与虚拟机**

   ```bash
   bash
   # 停止虚拟机
   multipass stop ubuntu-niulink
   ```

   ​**注意**：停止服务可避免资源冲突，确保配置修改安全生效。

3. ​**调整资源配置**

   ```bash
   bash
   # 设置CPU核心数（需小于物理核心数，建议预留20%资源给宿主机）
   multipass set local.ubuntu-niulink.cpus=20  

   # 注意单位应为数值而非"20G"

   # 设置内存容量（建议不超过物理内存的70%）
   multipass set local.ubuntu-niulink.memory=32G

   # 设置存储空间（需考虑本地磁盘剩余容量）
   multipass set local.ubuntu-niulink.disk=500G
   ```

4. ​**启动验证**

   ```bash
   bash
   # 检查资源配置是否生效
   multipass start ubuntu-niulink
   multipass info ubuntu-niulink
   ```
