The code assumes that def->vcpus == nvcpupids, so when we setup fake CPU pids for old QEMU with nvcpupids == 1, we cause the later code to read off the end of the array. This has fun results like sche_setaffinity(0, ...) which changes libvirtd's own CPU affinity, or even better sched_setaffinity($RANDOM, ...) which changes the affinity of a random OS process. --- src/qemu/qemu_process.c | 9 ++++----- src/util/virprocess.c | 1 + 2 files changed, 5 insertions(+), 5 deletions(-)
