spice is little endian for historical reasons.  There was (still is?)
ongoing work in both qxl emulation and spice code base to fix this, but
I don't think anyone went on testing and fixing things systematically on
bigendian machines.  You might want try asking on spice-devel though.

There also used to be some x86 dependency, but that was a small issue
compared to the byteordering and it got fixed while spice was enabled
for arm.

qxl + spice on ppc64le should do just fine, but only in case both host
and guest are le.

virtio-gpu is another option for that one.
