KVM via web cockpit for Ubuntu

I lived with Ubuntu and Windows 11 and 10 on Triple boot. With Ubuntu as a main operating system if I needed to use Windows I restarted computer and log into Windows.

Finally I really needed fast access to Windows system for my HOMM3 retro style blog to test some assets using program that only works on Windows.

It pushed me to finally take over with KVM as a new virtualisation tool in my vocabulary beside the Oracle VirtualBox that was already wide used by me.

Here useful tutorial for using virt-manager (Program on desktop instead of web access) and improving performance of VM:

KVM enabling Shared folder

1. Create directory for shared folder, remember it must be with execution of parent folders at least as chmod +x / and chmod 777 / for exact folder to share.
2. For shared folders install sudo apt install virtiofsd then restart service `sudo systemctl restart libvirtd
3. Under env EDITOR=nano sudo virsh edit Win11 user can edit KVM settings.
4. Download and install WinFSP in VM and install .msi file to make the shared folder visible on VM. https://github.com/virtio-win/kvm-guest-drivers-windows/wiki/Virtiofs:-Shared-file-system
5. Enable the VirtIO-FS Service on VM if Error 1053 showed there must be something wrong with loading drivers. Look again to github there I found solution last time.
