Using virt-manager, here's the error i get. last updated my system when the xz thing happened if needed

Unable to connect to libvirt qemu:///system.

Failed to connect socket to '/var/run/libvirt/virtqemud-sock': No such file or directory

Libvirt URI is: qemu:///system

Re: "Unable to connect to libvirt qemu:///system."

You have followed https://wiki.archlinux.org/title/Libvirt#Configuration ?

Why are you using an unsupported aur helper to install packages from official repos ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

If i put in a package name that's in an official repo into yay it acts the same as if i had done pacman -S instead (i assume)

Don't assume, investigate . Read https://wiki.archlinux.org/title/AUR_helpers and especially pay attention to the orange boxes.

run the 2 commands mentioned in https://wiki.archlinux.org/title/Libvirt#Test and post the full output (including the commands themselves).

Add the output of

$ systemctl status libvirtd.service
$ systemctl status virtlogd.service

Re: "Unable to connect to libvirt qemu:///system."

Ok, now re-run the virsh test commands with those services active.
