Setup KVM Hypervisor on SparkyLinux 2024.05

Virt-manager still appears to be the most powerful tool in regards of deployment and managment of KVM guests. Current version in Debian SID is 1:4.1.0-4. The presence of Web Cockpit Console is a nice way to manage KVM guest's via clicking the button "Launch remote viewer"  built into Cockpit Web Console. Bridge attached to external network interface was also created utilizing network management section inside Web Console and provides an alternative for guests attachment via NAT.
