#boot 怎么啟動的，如"fd"表示從文件啟動, "hd"從硬盤啟動, "cdrom"從光驅啟動 和 "network"從網絡啟動 #可以重復多行，指定不同的值，作為一個啟動設備列表。 #The dev attribute takes one of the values "fd", "hd", "cdrom" or "network"

## 使用virtio： 采用普通的驅動，即硬盤和網卡都采用默認配置情況下，硬盤是 ide 模式， 而網卡工作在 模擬的rtl 8139 網卡下，速度為100M 全雙工。 采用 virtio 驅動后，網卡工作在 1000M 的模式下，硬盤工作是SCSI模式下 <model type='virtio'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <input type='mouse' bus='ps2'/>
