No, it was installed:

I'm not seeing that.

The base system is SLES12, but Xen and the tools (including qemu) are
fairly recent xen-unstable. So the only thing SLES12 specific would be
domU kernel and qxl driver.

Thanks for your reply.
As you told the more probable fix/workaround can be in dom0's kernel and/or domU's kernel or qxl driver.
I tried to search about qxl suse package 0.1.0 repository (saw version in your message) but I not understand exactly what repository see.
About kernel I found this for patches added in suse:
https://github.com/openSUSE/kernel-source/tree/SLE12-SP1
Is it correct? With a fast look I not found patches related FWIK (but I had low knowledge)
Next week probably I'll try to restrict the search field trying suse domU in same dom0 I used (wheezy with kernel from backports and other packages update manually), I can try latest opensuse or is better try a SLED12 trial instead?

I found one patch probably related: https://build.opensuse.org/package/view_file/Virtualization/xen/stdvga-cache.patch?expand=1 you used it in your test?

is possible to use configure instead: ./configure --with-extra-qemuu-configure-args="--enable-spice --enable-usb-redir"
