In order to validate the theory that the problem with 3D acceleation on f25-muse is related to the viewer only, I am rebuilding the whole Spice package.

Running the following with the built-in virt-viewer shows the same display artefacts:

virt-viewer -c qemu:///system f25-muse

Building spice-gtk

The spice-protocol packages build directly. However, the build of spice-gtk fails with:

make[4]: Entering directory '/home/ddd/Work/spice/spice-gtk/spice-common/common'
  GEN      generated_client_demarshallers.c

I had already run into that on March 8 (I love the new blog format for the speed at which I can find this kind of thing with a mere grep). But the solution that worked back then, pip install six, does not work this time.

This is a failure in spice-common/common. The Makefile looks like this:

generated_client_demarshallers.c: $(top_srcdir)/spice.proto $(MARSHALLERS_DEPS)
	$(AM_V_GEN)$(PYTHON) $(top_srcdir)/spice_codegen.py --generate-demarshallers --client --include common/messages.h $< $@ >/dev/null

Running the command make -n to see the command as it is executed. Then execute it manually:

ddd@muse[master] common> /usr/bin/python ../spice_codegen.py --generate-demarshallers --client --include common/messages.h ../spice.proto generated_client_demarshallers.c
Module pyparsing not found.

Why does python send this message on stdout and not stderr? Tested that by adding > /dev/null at end of command.

Fixing with:

 pip install pyparsing 

  GISCAN   SpiceClientGLib-2.0.gir
gcc: error: /usr/lib/rpm/redhat/redhat-hardened-cc1: No such file or directory
Traceback (most recent call last):

This specific error is fixed by installing redhat-rpm-config:

dnf install redhat-rpm-config

Missing codecs from configure:

configure: WARNING: The avdec_h264 GStreamer element(s) are missing. You should be able to find them in the gstreamer-libav 1.0 package.

Fixed with:

dnf install gstreamer1-libav

Building virt-viewer

This one had some patches from me. Rebased on a recent master. Interestingly, the origin no longer works, it was https://git.fedorahosted.org/git/virt-viewer.git. Found https://pagure.io/virt-viewer.git with some commits from 6 days ago.

Running autogen.sh is missing some functionality, specifically GTK_VNC, LIBVIRT and OVIRT:

Had to install some additional optional elements to get a full-featured virt-viewer:

dnf install gtk-vnc-devel gtk-vnc2-devel libvirt-devel libgovirt-devel

Very strangely, autogen.sh fails after adding the packages:

checking for LIBVIRT... no
configure: error: Package requirements (libvirt >= 0.10.0 libvirt-glib-1.0 >= 0.1.8) were not met:


No package 'libvirt-glib-1.0' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables LIBVIRT_CFLAGS
and LIBVIRT_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Apparently, I also need

dnf install libvirt-glib-devel

Finally built virt-viewer from master, same issue on the display. Ah, interesting.
