spice on 32-bit

[Ken Dreyer]

Are there any plans to get Fedora's 32-bit qemu-kvm package working
with Spice support? Is this a limitation of the buildsystem, or
something else?

I am unaware of any plans to make this work, though that does not mean
that none exist.  It is a matter of code, and the spice-server is a
64bit only build as well.  I have never heard of any planned 32bit host
spice support.

No plans, but no limitation either AFAICT.

IIUC, in the past, the SPICE protocol itself was not endian-safe,
nor 32/64-bit invariant. I assume those problems have all been
fixed in latest SPICE protocol specs, and it just remains that
the actual impl code which needs fixing up ?

All I meant was that there is nothing inherently 64 bit about spice. The
marshalling code does make for an easy place to deal with endianess of the
protocol vs the machine. A quick grep shows there is SPICE_BYTESWAP in macros.h
and it is used by generated_demarshaller.c (and I'll assume the others). 64/32
is something that needs other checking. I'd assume if someone got to building it
on 32 bit they will find pretty fast if there is anything to fix.
