[Qemu-devel] [Bug 848571] [NEW] qemu does not generate a qemu-kvm.stp tapset file

[William Cohen]

Public bug reported:

To make the systemtap probing easier to use qemu generates qemu*.stp
files with aliases for various events for each of the executables. The
installer places these files in /usr/share/systemtap/tapset/.  These
files are generated by the tracetool. However, the /usr/bin/qemu-kvm is
produced with a copy:

 cp -a x86_64-softmmu/qemu-system-x86_64 qemu-kvm

No matching qemu-kvm.stp generated for the qemu-kvm executable. It would
be really nice if that tapset file is generated so people can use more
symbolic probe points.

Jes Sorensen added an option to make this possible:

http://repo.or.cz/w/qemu.git/commitdiff/e323c93edf3abb67c37b8e08b78da4835880f12e

Distro packaging scripts can make use of this tracetool option to
generate .stp files for qemu-kvm in its install path.

I think you need to file a bug with your distro.

You are correct. the qemu.spec file is doing the copy.
