libvirt-go 设置不同类型磁盘：SCSI、IDE、SATA、VIRIO

可以使用以下代码来设置四个磁盘，类型分别为'scsi'、'ide'、'sata'、'virtio'，大小均为10GB：

import (
    "github.com/libvirt/libvirt-go"
    "github.com/libvirt/libvirt-go-xml"
)

func main() {
    conn, err := libvirt.NewConnect("qemu:///system")
    if err != nil {
        panic(err)
    }
    defer conn.Close()

    domainXML := libvirtxml.Domain{
