virt-manager: QEMU/KVM - connecting...

virt-manager can't seem to connect to qemu:///system but i don't know what could be really causing it or how to fix it. I have both gpu and cpu from amd

i installed the following packages

sudo pacman -S qemu virt-manager virt-viewer vde2 bridge-utils openbsd-netcat libguestfs dnsmasq edk2-ovmf iptables-nft dmidecode

my user is part of the kvm,libvirt,libvirt-qemu,qemu groups.

/etc/libvirt/libvirtd.conf and /etc/libvirt/qemu.conf are edited exactly in the way the virt-manager archwiki page instruct me to do.

here below is the output of various command from the following pages https://wiki.archlinux.org/title/Virt-Manager https://wiki.archlinux.org/title/KVM

LC_ALL=C lscpu | grep Virtualization

i did a lot of research before resolving to posting but i am sure i am missing something maybe obvious.

Re: virt-manager: QEMU/KVM - connecting...

I had a same problem after update. It solved by changing as below.

vi /etc/libvirt/libvirtd.conf
unix_sock_group = "libvirt"
unix_sock_rw_perms = "0770"
auth_unix_rw = "none"

Hope it works...
