I think this is a spice issue. I think anyone who has successfully
used these buttons wasn't using spice.
spice-protocol::spice/enums.h only gives SpiceMouseButton types of
LEFT, MIDDLE, RIGHT, UP, and DOWN.
spice-gtk::src/spide-widget.c::button_event() calls

Running "remote-viewer --spice-debug" does show events for pushing the
scroll wheel left and right:

0:0 button_event press: button 8, state 0x10

I didn't make it very clear that my Arch Linux guest didn't had tablet
emulation. On it, evtest only shows "ImExPS/2 Generic Explorer

Mouse #2: QEMU PS/2 Mouse
* Mouse #3: QEMU HID
Probably the PS/2 mouse is not used at all because the HID Tablet takes

which mouse is currently used. If you disable or uninstall the HID
Tablet, the PS/2 mouse should take over.
"IMEX" is short for Intelli Mouse Explorer.

spice-protocol all git versions from the past week or so.
I have a Logitech G600 mouse. The scroll wheel can be pushed left or right.
On Arch Linux host, "evtest" shows these as event codes 275 (BTN_SIDE)
and 276 (BTN_EXTRA.) In
