Libvirt API

API Reference
RPC Protocol
- 基于 XDR (External Data Representation) 序列化
- SunRPC/ONCRPC 协议
客户端库

核心概念

对象	说明
`virConnectPtr`	Hypervisor 连接
`virDomainPtr`	虚拟机 (运行中或已定义)
`virNetworkPtr`	虚拟网络
`virStoragePool`	存储池
`virStorageVol`	存储卷

Go 示例

package main

import (
	"fmt"
	"net"
	"time"

	"github.com/digitalocean/go-libvirt"
)

func main() {
	// Unix socket 连接
	c, err := net.DialTimeout("unix", "/var/run/libvirt/libvirt-sock", 2*time.Second)
	if err != nil {
		panic(err)
	}

	l := libvirt.New(c)
	if err := l.Connect(); err != nil {
		panic(err)
	}
	defer l.Disconnect()

	v, _ := l.Version()
	fmt.Println("Version:", v)

	domains, _, _ := l.ConnectListAllDomains(1, 0)
	for _, d := range domains {
		fmt.Printf("%d %s %x\n", d.ID, d.Name, d.UUID)
	}
}

Java 示例

java

import org.libvirt.Connect;
import org.libvirt.ConnectAuthDefault;

public class LibvirtExample {
    public static void main(String[] args) throws Exception {
        Connect conn = new Connect("qemu:///system", new ConnectAuthDefault(), 0);
        System.out.println("Hypervisor: " + conn.getType());
        System.out.println("Version: " + conn.getLibVirVersion());
    }
}
