See the extended -smp options:
-smp n[,maxcpus=cpus][,cores=cores][,threads=threads][,sockets=sockets]
set the number of CPUs to 'n' [default=1]
maxcpus= maximum number of total cpus, including
offline CPUs for hotplug, etc
cores= number of CPU cores on one socket
threads= number of threads on one CPU core
sockets= number of discrete sockets in the system
Try something like:
-smp 4,cores=2,threads=2,sockets=1

Great - the correct combination made it :-)
But the SMP-Performance-Benchmark is horrible :-(
"Only" between 0.35 and 1.05 for the above combination.
I have the same architecture on the host (2 cores w/ ht enabled) so there
are enough real cores available for computation.
Any idea what could slow down the performance here?
Best regards,
Erik
