*UPDATE*
I was able to solve this by installing dnsmasq, firewalld, and dmidecode. I then double checked line 726 of /etc/libvirt/qemu.conf to find I needed to correct a typo in...
nvram = [
"/usr/share/ovmf/x64/OVMF_CODE.fd:/usr/share/ovmf/x64/OVMF_VARS.fd"
]*END UPDATE*
Trying to setup Qemu Kvm gpu passthrough for the first time using the Arch Wiki guide. All steps done and verified from wiki to the point of starting virt-manager.
When I start virt-manager I get, Unable to connect to libvirt qemu:///system. The error is..
Unable to connect to libvirt qemu:///system.
Verify that the 'libvirtd' daemon is running.
Libvirt URI is: qemu:///system
Traceback (most recent call last):

libvirtError: Failed to connect socket to '/var/run/libvirt/libvirt-sock': No such file or directoryI am in the libvirt group, the services libvirtd.service and its logging component virtlogd.socket are running, I have uninstalled and reinstalled virt-manager.
Running virt-manager with sudo produces the same error even after relogging.
Upon looking into /var/run/libvirt/libvirt-sock, libvirt-sock is NOT there but virtlockd-sock is there?
Any help is appreciated,
Thank you, Drew

After a fresh install of Arch I am still in this same situation. Below is the output of status libvirtd.service

I think you should first have a look at "configuration file syntax error: /etc/libvirt/qemu.conf:726: expecting a value" before doing anything else.

I too had the same problem. I followed Drew's instructions and got QEMU/KVM with virt-manger up and running.
Thank you Drew.
