====

Package `libvirt` provides a pure Go interface for interacting with Libvirt.

Rather than using Libvirt's C bindings, this package makes use of
Libvirt's RPC interface, as documented [here](https://libvirt.org/internals/rpc.html).
Connections to the libvirt server may be local, or remote. RPC packets are encoded
using the XDR standard as defined by [RFC 4506](https://tools.ietf.org/html/rfc4506.html).

This should be considered a work in progress. Most functionaly provided by the C
bindings have not yet made their way into this library. [Pull requests are welcome](https://github.com/digitalocean/go-libvirt/blob/master/CONTRIBUTING.md)!
The definition of the RPC protocol is in the libvirt source tree under [src/rpc/virnetprotocol.x](https://github.com/libvirt/libvirt/blob/master/src/rpc/virnetprotocol.x).

Warning
-------

All packages contained in this repository should be treated as **pre-production
software with an unstable API**.

While these package are reasonably well-tested and have seen some use inside of
DigitalOcean, there may be subtle bugs which could cause the packages to act
in unexpected ways.  Use at your own risk!

In addition, the API is not considered stable at this time.  If you would like
to include package `libvirt` in a project, we highly recommend vendoring it into
your project.

Example
-------

```go
package main

import (
	"fmt"
	"log"
	"net"
	"time"

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

func main() {
	//c, err := net.DialTimeout("tcp", "127.0.0.1:16509", 2*time.Second)
	//c, err := net.DialTimeout("tcp", "192.168.1.12:16509", 2*time.Second)
	c, err := net.DialTimeout("unix", "/var/run/libvirt/libvirt-sock", 2*time.Second)
	if err != nil {
		log.Fatalf("failed to dial libvirt: %v", err)
	}

	l := libvirt.New(c)
	if err := l.Connect(); err != nil {
		log.Fatalf("failed to connect: %v", err)
	}

	v, err := l.Version()
	if err != nil {
		log.Fatalf("failed to retrieve libvirt version: %v", err)
	}
	fmt.Println("Version:", v)

	domains, err := l.Domains()
	if err != nil {
		log.Fatalf("failed to retrieve domains: %v", err)
	}

	fmt.Println("ID\tName\t\tUUID")
	fmt.Printf("--------------------------------------------------------\n")
	for _, d := range domains {
		fmt.Printf("%d\t%s\t%x\n", d.ID, d.Name, d.UUID)
	}

	if err := l.Disconnect(); err != nil {
		log.Fatal("failed to disconnect: %v", err)
	}
}
