(Xen already has spice support in Xen 4.2, and making QXL working is possible when xen-unstable switches to using the most recent Qemu upstream branch during the Xen 4.3 development cycle) Hopefully those links help.. -- Pasi > Best Regards, > Bei Guan > _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
