The performance impact of various debug options on Fedora Rawhide debug kernels

2022-07-24 Thread Richard W.M. Jones
The current Fedora Rawhide kernels are too slow to run libguestfs tests when doing Koji builds. These run in a qemu VM, running the Rawhide kernel, emulated using software virtualization (ie. TCG). They now time out because these kernels are so slow. Until fairly recently they were slow but worki
