title: QEMU+Virt-manager can't connect to virtlxcd-sock
body: <p>I've installed qemu virt-manager libvirt on Linux Mint 20, I have a AMD FX(tm)-4300 Quad-Core Processor with AMD-V enabled in the bios, restarted a lot but virt-manager(Virtual Machine Manager) is saying:</p>
  <pre><code>Unable to connect to libvirt lxc:///.
  Failed to connect socket to '/var/run/libvirt/virtlxcd-sock': No such file or directory
  Libvirt URI is: lxc:///
  </code></pre>
  <p>I am running this locally. The file/socket does not exist, but there is a &quot;libvirt-sock&quot; (and other files) in that folder.
  The service is running, but reporting the same error:</p>

  <p>I'm updated my kernel to 5.8.5-generic, but other than that, running Mint 20 (based on Ubuntu focal). Anyone know how to fix this, or display a log as to why virtlxcd-sock is not being created?
  Also tried sudo chmod 777 on the libvirt subfolder and restarted libvirtd, same error.</p>
