libvirt 和 virt-manager - 无法完成安装：“内部错误：不支持的输入总线 usb”

  • 772

我按照以下步骤使用 Xen 作为管理程序和 virt-manager (libvirt) 作为管理模块来创建虚拟机。尝试创建虚拟机时出现以下错误：

无法完成安装：“内部错误：不支持的输入总线 USB”

错误详情：

Unable to complete install: 'internal error: unsupported input bus usb'

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 75, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/create.py", line 2276, in _do_async_install
    guest.start_install(meter=meter)
  File "/usr/share/virt-manager/virtinst/guest.py", line 461, in start_install
    doboot, transient)
  File "/usr/share/virt-manager/virtinst/guest.py", line 397, in _create_guest
    domain = self.conn.createXML(install_xml or final_xml, 0)
  File "/usr/lib/python3.7/site-packages/libvirt.py", line 3717, in createXML
    if ret is None:raise libvirtError('virDomainCreateXML() failed', conn=self)
libvirt.libvirtError: internal error: unsupported input bus usb

注意 I：部署过程遵循此处https://www.youtube.com/watch?v=BwkmDM-Gpzc和此处https://wiki.centos.org/HowTos/Xen/Xen4QuickStart的说明。
注二： Xen Hypervisor 使用 CentOS 7 作为“domu”。

    我更新了我的版本，问题不再出现！

    以下是 Cole Robinson 在“libvirt-users”邮件列表 ([email protected]) 上回复我的内容：

    Coincidentally this a bug I fixed just this morning:

     guest: Don't add usb tablet for xen PV

     xen PV doesn't have USB support


But you can work around it: at the end of the 'new vm' wizard, click 
'customize before install', and in the VM details window, remove the 
tablet device, then finish the install. That should make things work

    谢谢！=D
