Comment 1 Daniel Berrangé 2011-09-13 09:09:49 UTC

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 11:55:56 UTC

qemu-0.15.0-4.fc16 has been submitted as an update for Fedora 16.

Comment 4 William Cohen 2011-09-13 13:59:18 UTC

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 Berrangé 2011-09-13 14:11:40 UTC

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 Berrangé 2011-09-13 14:12:05 UTC

The full addition can be seen in Fedora GIT for qemu:
