Description of problem:
table 18.3 in Administration guide says:
"""
Run export SPICE_DEBUG_LEVEL=5 on the host/hypervisor prior to launching the guest.
"""

That's misleading. Libvirt sets a clean environment for VMs. The only way to set the environment value of qemu process is a custom hook before VM start that will augment domain XML to include the environment variable. Example of such a hook is in attachment and to set spice_debug variable of it's environment, UserDefinedVMProperties on the engine should be set to "spice_debug=^[0-9]+$" and the particular value then can be set in webadmin -> Edit VM -> Custom Options
