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?
About xen I take a look here: https://build.opensuse.org/package/show/Virtualization/xen 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? I saw also that there is a patch anymore needed: https://build.opensuse.org/package/view_file/Virtualization/xen/qemu-xen-enable-spice-support.patch?expand=1 Since this: http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=9aa2cef51f3dced396a5ae10de586206956f9ffd is possible to use configure instead: ./configure --with-extra-qemuu-configure-args="--enable-spice --enable-usb-redir"
