Attempt to upgrade Manjaro 23.1 via Manjaro Testing branch

The core target of this post is evaluating current status of Manjaro Testing instance .

Changing to another branch

In order to access a branch, you need to change your pacman-mirrors configuration. You are supposed substitute the value colored in blue (for illustrative purposes only) to one of the following: stable, testing or unstable.

 $ sudo pacman-mirrors --api --set-branch {branch}

Run the pacman-mirrors tool with the --fasttrack option to fetch all mirrors to the list that consumes minimum time.

   $ sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syu

Manjaro Testing is runing kernel 6.7.4, System-wide Python appears to be 3.12.1, libvirt to have version 10.0.0 . 
The libvirt version has been displayed via virsh console. 
KVM Hypervisor and tools may be either smoothly 
upgraded from 23.1 or installed on Manjaro testing 
instance from scratch. In the last case after command
$ sudo pacman -S qemu virt-manager virt-viewer dnsmasq vde2 bridge-utils openbsd-netcat dmidecod 
The default option for qemu "all" should be selected
