fix: use virsh define for VM creation instead of virt-install
virt-install requires storage pool driver which is not available on this system. Switched to direct virsh define using XML template which works without storage pools. Changes: - Replaced virt-install with virsh define + start - Pre-create disk with qemu-img before VM definition - Copy ISO to /var/lib/libvirt/images with proper ownership - Use XML template with variable substitution - VM now appears in virt-manager under QEMU/KVM connection VM knel-football-test is now running and visible in virt-manager. 💘 Generated with Crush Assisted-by: GLM-4.7 via Crush <crush@charm.land>
