我正在尝试为 KVM 设置 GPU 直通，但一直面临这个严重问题。基本上，它告诉我要验证 libvirt 是否正在运行。
Unable to connect to libvirt qemu:///system.
Verify that the 'libvirtd' daemon is running.
Libvirt URI is: qemu:///system
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/connection.py", line 922, in _do_open
self._backend.open(cb, data)
File "/usr/share/virt-manager/virtinst/connection.py", line 153, in open
conn = libvirt.openAuth(self._open_uri,
File "/usr/lib/python3/dist-packages/libvirt.py", line 148, in openAuth
raise libvirtError('virConnectOpenAuth() failed')
libvirt.libvirtError: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Connection refused
当我检查 libvirt 的状态时，它确实没有处于活动状态。但我自己找不到解决方案。
