The kvm_create_max_vcpus is generic enough so that it works out of the box on POWER, too. We just have to provide some stubs for linking the code from kvm_util.c. Note that you also might have to do "ulimit -n 2500" before running the test, to avoid that it runs out of file handles for the vCPUs. Signed-off-by: Thomas Huth <thuth@redhat.com> --- RFC since the stubs are a little bit ugly (does someone here like to implement them?), and since it's a little bit annoying that you have to raise the ulimit for this test in case the kernel provides more vCPUs than the default ulimit... tools/testing/selftests/kvm/Makefile | 6 +++ .../selftests/kvm/lib/powerpc/processor.c | 37 +++++++++++++++++++ 2 files changed, 43 insertions(+) create mode 100644 tools/testing/selftests/kvm/lib/powerpc/processor.c
