Fist we deploy Debian Testing as L1 KVM Guest (8 VCPs,16 GB RAM,CachyOS 6.13.4 Kernel). Second step would be to install KVM Hypervisor on Debian Testing (Trixie Alpha) Virtual machine. Afterwards it appears possible to setup Hypland with ML4W 2.9.8.2 Dotfiles as L2 KVM Guest serving a dual DE for CachyOS which had been installed first as L2 KVM Guest inside Debian Testing L1 level. Running of Hypland with ML4W 2.9.8.2 Dotfiles (L2) doesn’t require enabling 3D acceleration in Virt-manager’s configuration running on top of Debian Testing as KVM Guest
