Fwiw, I'd first get familiar with SPICE/qemu outside of OpenStack.
spice-server might be badly named, it's a shared library (.so)
implementing the SPICE protocol. QEMU uses it, so does Xspice.
If QEMU is built with SPICE support (if QEMU is linked with
libspice-server.so), then it's possible to start a virtual machine
which will use the SPICE protocol, but this has to be done explicitly.
Simplest form is
qemu-system-x86_64 -spice port=5900,disable-ticketing

Xspice would be running in the guest and lets you access an X session
over SPICE.
This is different from using native QEMU SPICE support, where you would
not need to do anything except tell QEMU that you want to use it.

This looks like a bug, but it's not clear what's happening. Did you take
a look at libvirt logs for that guest? They are either in
/var/log/libvirt/qemu/ or ~/.cache/libvirt/qemu/log/
