   * Network configuration (of 4 x 1 GB/s ethernet ports)   * Network configuration (of 4 x 1 GB/s ethernet ports)
     * Access to public internet modem, via 1 Ethernet port - **the WAN (Wide Area Network) connection**     * Access to public internet modem, via 1 Ethernet port - **the WAN (Wide Area Network) connection**
-      * modem is VDSL based, set into bridge mode to allow connection to control using this machine as router +      * Early 2024 I was upgraded to a full fibre internet connection.  A connection box / modem converts the fibre to RJ45 1GB/s ethernet IP connection inside the house.  The old ISP supplied VDSL modem/router does have a WAN input that works, however the all the ethernet connections are limited to 100Mb/s.  Hence on the 250Mb/s plan this router is not fully suitable for purpose. 
-        * modem is currently set to use direct remote DHCP/IP as specified by ISP (Internet Service Provider requirements), was originally setup using PPPoE. +
-        * There is also as separate static IP address setup to access and control the modem+

The bridge network setup has the following required features:
       * It allows connections of multiple physical Ethernet ports to a bridge interface device, with the bridge effectively acting as a network switch for the connected physical ports.  (On my home server I have 4 x 1GB/s Ethernet ports and an add in PCIe card that provided a 2.5GB/s Ethernet port. All these physical ports are connected to a common network bridge device. This seem to just work, and each physical device seems to operate at its specific capacity.)       * It allows connections of multiple physical Ethernet ports to a bridge interface device, with the bridge effectively acting as a network switch for the connected physical ports.  (On my home server I have 4 x 1GB/s Ethernet ports and an add in PCIe card that provided a 2.5GB/s Ethernet port.

 I decided to try QEMU/KVM setup as follows: I decided to try QEMU/KVM setup as follows:
-  *''sudo apt install qemu qemu-system-x86 qemu-system qemu-utils libvirt-clients libvirt-daemon-system virtinst'' (qemu-kvm is now call / replaced by qemu-system-x86 in Debian 11, presumably only for x86 systems) +  *''%%sudo apt install qemu-system qemu-system-x86 qemu-utils libvirt-clients libvirt-daemon libvirt-daemon-system virtinst --no-install-recommends%%''

-  *''sudo apt install qemu-system '' +====package descriptions==== 
-I did not install libguestfs-tools, as I did not think I would need it +In most cases details these packages can be seen at [[https://www.debian.org/distrib/packages|Debian Packages]]. 
-  *''sudo apt install libvirt-bin''+++++tldr;| 
 +  *''qemu'' - [[https://wiki.qemu.org/Main_Page|QEMU]]  is a generic and open source machine emulator and virtualiser, and is now a dummy package, it no longer works on Debian 12. 
 +  *<fs small>''qemu-kvm'' - was made a wrapper script to qemu-system and is now redundant</fs> 
 +  *''qemu-system'' is a meta package that call the correct system pack, e.g. qemu-system-x86 (qemu-kvm is now call / replaced by qemu-system-x86 in Debian 11) 
 +  *''qemu-system-x86'' is the actual system peripheral emulator and virtualiser for x86 systems 
 +    *''qemu-utils'' provides utilities for QEMU disk activities 
 +  *''libvirt-daemon'' - daemon libvirtd to manage the hypervisors 
 +    *''libvirt-daemon-system'' - configuration files to run the libvirt daemon as a system service 
 +  *''libvirt-clients'' - contains the libvirt shell virsh and other client binaries 
 +  *''virtinst'' - utilities to create and edit virtual machines 
 +  *''libspice-server1'' - Implements the server side of the SPICE protocol 
 +  *''virt-viewer'' - The console is accessed using the VNC or SPICE protocol. (Client software) 
 +  *''virt-manager'' - desktop application for managing virtual machines. (Client software) 
 +  *''libspice-client-gtk-3.0-5'' - libspice-gtk3 provides gtk3 widget to show spice display and accept user input.  (Client software)
