Virt-manager“无法完成安装：‘请求的操作无效:网络’默认‘不是活动的’”

Question

我刚刚在Arch上安装了virt-manager，我已经完成了创建VM的所有步骤，但是当我单击步骤5/5上的"Finish“时，我得到了两个弹出对话框：

无法完成安装：“请求的操作无效:网络”默认“未激活”

详细信息：

Unable to complete install: 'Requested operation is not valid: network 'default' is not active'

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 72, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/createvm.py", line 2008, in _do_async_install
    installer.start_install(guest, meter=meter)
  File "/usr/share/virt-manager/virtinst/install/installer.py", line 695, in start_install
    domain = self._create_guest(
  File "/usr/share/virt-manager/virtinst/install/installer.py", line 637, in _create_guest
    domain = self.conn.createXML(initial_xml or final_xml, 0)
  File "/usr/lib/python3.10/site-packages/libvirt.py", line 4408, in createXML
    raise libvirtError('virDomainCreateXML() failed')
libvirt.libvirtError: Requested operation is not valid: network 'default' is not active

无法启动虚拟网络“默认”：无法创建桥virbr0:包未安装

详细信息：

Could not start virtual network 'default': Unable to create bridge virbr0: Package not installed

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/device/netlist.py", line 208, in _check_network_is_running
    netobj.start()
  File "/usr/share/virt-manager/virtManager/object/libvirtobject.py", line 57, in newfn
    ret = fn(self, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/object/network.py", line 69, in start
    self._backend.create()
  File "/usr/lib/python3.10/site-packages/libvirt.py", line 3474, in create
    raise libvirtError('virNetworkCreate() failed')
libvirt.libvirtError: Unable to create bridge virbr0: Package not installed

我看到在virbr0之后说“没有安装软件包”，所以我尝试了：$ sudo pacman -Syu virbr0 --没有找到$ yay -Syu virbr0 --也没有找到

我希望你已经解决了。通常，您应该使用以下命令检查libvirt网络：

virsh net-list
