Comment 1 Daniel Berrange 2011-09-13 05:09:49 EDT
Thanks for the specfile patch. It'll need a small tweak to make sure each tapset gets put into the appropriate sub-RPM for that arch, but I'll do that when I apply it to GIT

Comment 3 Fedora Update System 2011-09-13 07:55:56 EDT
qemu-0.15.0-4.fc16 has been submitted as an update for Fedora 16.
Comment 4 William Cohen 2011-09-13 09:59:18 EDT
One deficiency in the currently patch for the qemu.spec is there is no qemu-kvm.stp being generated. Given that /usr/bin/qemu-kvm is the binary being used by default, the qemu.spec should also have tracetool generate a matching qemu-kvm.stp.
Comment 5 Daniel Berrange 2011-09-13 10:11:40 EDT
I fixed that with this addition to the specfile

+./scripts/tracetool --dtrace --binary %{_bindir}/qemu-kvm \
+  --target-arch x86_64 --target-type system --stap \
+  --probe-prefix qemu.kvm < ./trace-events > qemu-kvm.stp
Comment 6 Daniel Berrange 2011-09-13 10:12:05 EDT
