After saw the full backtrace I saw on qemu git recent patches with fix
on input, than I tried to update qemu to latest commit
(82c6f513735297ad76acaaf2e87f0c5a0b3647a7) and now the segfault seems
solve, I did some fast test with vnc and spice on same pv domUs without
qemu crashes.
About libxl patch of spice support for pv domUs I'll improve it
following your reply and also try to find more details about pointer not
visible but working with spice on pv domUs.
Thanks to all for your help.
