Last weekend we migrate two of our LPARS from a EC12 to a z/14. Also, activate
the multithread feature under VM with SET MT TYPE IFL 2. Checking one of our
Linux guest and do a CPUINFO it shows no thread and the old machine number
cat /proc/cpuinfo

Do we need to run something at the Linux site to activate or refresh the
machine and multithread?
We have z/VM 6.4 and SLES 12
