As it also affects KVM:
def get_default_jobs():
if multiprocessing.cpu_count > 1:
if kvm_available(vmcls.arch):
return multiprocessing.cpu_count() // 2
elif os.uname().machine == "x86_64" and \
vmcls.arch in ["aarch64", "x86_64", "i386"]:
# MTTCG is available on these arches and we can allow more
cores.
# But only up to a reasonable limit. User can always override
# these limits with --jobs.
return min(multiprocessing.cpu_count() // 2, 8)
else:
return 1
