libvirt 和 virt-manager - 無法完成安裝：“內部錯誤：不支持的輸入匯流排 usb”

我按照以下步驟使用 Xen 作為管理程序和 virt-manager (libvirt) 作為管理模組來創建虛擬機。嘗試創建虛擬機時出現以下錯誤：

無法完成安裝：“內部錯誤：不支持的輸入匯流排 USB”

錯誤詳情：

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)

   guest.start_install(meter=meter)

   if ret is None:raise libvirtError('virDomainCreateXML() failed', conn=self)

**注意 I：**部署過程遵循此處https://www.youtube.com/watch?v=BwkmDM-Gpzc>和此處<https://wiki.centos.org/HowTos/Xen/Xen4QuickStart的說明。

註二： Xen Hypervisor 使用 CentOS 7 作為“domu”。

腳步：

我更新了我的版本，問題不再出現！

以下是 Cole Robinson 在“libvirt-users”郵件列表 (libvirt-users@redhat.com) 上回复我的內容：

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

謝謝！=D
