我一直在尝试使用 virsh attah-disk 附加一个 qcow2 文件作为附加存储源。我使用的语法是(来自互联网):
virsh attach-disk --driver file vm2 disk2.qcow2 hdc
如果 vm 正在运行或暂停,它会显示:
error: this function is not supported by the hypervisor: disk bus 'ide' cannot be hotplugged.
如果 vm 已关闭,则显示:
error: Requested operation is not valid: cannot attach device on inactive domain
我不确定 hdc 参数。我也尝试将附加设备功能与 xml 文件一起使用:
<disk type="file" device="disk">
<driver name="file"/>
<source file="/gfs1/disk2.qcow2"/>
<target dev="hdc"/>
</disk>
但这也表明:
error: Failed to attach device from /gfs1/disk2tovm2.xml
error: this function is not supported by the hypervisor: disk bus 'ide' cannot be hotplugged.
我查看了许多示例,但没有一个有效,并且都具有几乎相同的语法。如果有人可以帮助我找出错误。
