Check whether running
 qemu-system-x86_64 -spice help
produces a list of "spice options" describing the sub-options.

If it does, then there's some problem with the specific option string
you're using (and you should tell us what your whole command line is).

If it doesn't produce anything, then your QEMU binary was built without
SPICE support, and you'll need to rebuild it from source.

When you run configure, by default QEMU will build optional
features like SPICE if it can find the libraries it needs for them,
and if it can't find the libraries it won't build the optional feature.
You can pass configure the "--enable-spice" option which will force
configure to fail if it can't find the libraries it needs. Then
you'll need to make sure you have those libraries available, and
once you do QEMU will build with SPICE support enabled.
