Hi. As bug #947020 was closed without dealing with all wishes expressed in it I'm open a follow up here: IMHO, for security reasons, SPICE should be usable as well via UNIX sockets instead of TCP. This of course doesn't only apply to libvirt/qemu on the server side, but also to the client side (i.e. virt-manager and perhaps virt-viewer as well). Cheers, Chris.
This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle. Changing version to '22'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora22
qemu will support this with 2.3.0, but I don't think libvirt supports it for spice yet http://git.qemu.org/?p=qemu.git;a=commit;h=fe4831b1e7e7007ae15ae0470a06898660ab3877
