Bring CachyOS KVM Hypervisor along with KDE Plasma 6.5.2 and Kernel 6.17.7 to Arch Linux VM

UPDATE as of 11/27/2025

Would you experience any issues with  cachyos-rate-mirrors, just remind that cachyos-rate-mirrors is a wrapper script for the rate-mirrors tool, specifically configured to rank and update both Arch Linux and CachyOS  mirrors for the user's mirror list file. It automatically tests available mirrors based on speed and synchronization status to ensure pacman downloads are optimized. It's a wrapper: It is not a replacement for rate-mirrors but rather a specific version or a script that uses rate-mirrors's underlying functionality. See man pages for rate-mirrors.

END UPDATE  

This post is an immediate follow up for Fedora 43 KVM Hypervisor && bring CachyOS KDE Plasma 6.5.1 along with kernel to Arch Linux VM  It is quite clear that there is a way to automatically start services virtstoraged, virtnetworkd, virtqemud, virtnodedevd on Arch Linux VM , however I was not lucky enough to automate this procedure.

$ sudo pacman -S qemu-desktop libvirt virt-manager bridge-utils dnsmasq edk2-ovmf

$ sudo systemctl enable libvirtd.service

$ sudo systemctl start libvirtd.service

$ sudo usermod -aG libvirt $(whoami)

$ sudo systemctl restart libvirtd.service

 

RELOGIN to SESSION

 

The following commands run automatically on Fedora 43 and no manual intervention is required.

$ sudo systemctl enable virtstoraged

$ sudo systemctl start virtstoraged

$ sudo systemctl enable virtnetworkd

$ sudo systemctl start virtnetworkd

$ sudo systemctl enable virtqemud

$ sudo systemctl start virtqemud

=================================

$ sudo systemctl start virtnodedevd.socket

$ sudo systemctl enable virtnodedevd.socket

$ sudo systemctl start virtnodedevd

$ sudo systemctl enable virtnodedevd

=================================

Start default network

$ sudo virsh net-start default

$ sudo virsh net-autostart default

Setup Web Cocpit Console and bridge0

Open port 9090/tcp say via ufw 

$ sudo pacman -S cockpit cockpit-machines

$ sudo systemctl enable --now cockpit.socket

 

Log into Web Cockpit Console

and activate bridge — bridge0 (for instance)

Cockpit embedded VNC Console

Having tuning described in https://lxer.com/module/newswire/view/358937/index.html  done, you may also perform a complete upgrade system to CachyOS . Final upgrade doesn't have any dependency with KVM Hypervisor setup and may be done before KVM installation.

$ pacman -Qqn | sudo pacman -S -
