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:
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:///
I am running this locally. The file/socket does not exist, but there is a "libvirt-sock" (and other files) in that folder. The service is running, but reporting the same error:

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.

Start virt-manager . Launch the Virtual Machine Manager application from the Applications menu and System Tools submenu. Alternatively, run the virt-manager command as root. Select the hypervisor and click the Connect button to connect to the remote hypervisor.
Use the following commands to start and stop libvirtd or check its status: tux > sudo systemctl start libvirtd tux > sudo systemctl status libvirtd libvirtd.
The libvirt LXC driver manages "Linux Containers". At their simplest, containers can just be thought of as a collection of processes, separated from the main host processes via a set of resource namespaces and constrained via control groups resource tunables.
Been googling for hours, finally found the one that worked for me, seems like installing libvirt and lxc does not install this package:
sudo apt install libvirt-daemon-driver-lxc
sudo systemctl restart libvirtd
