You could do this by directly changing the cpu type in database, but this is not supported operation. Just an example what would I do in this case (but proceed carefully before changing anything in the DB): $ su - postgres -c "psql -t engine -c \"SELECT split_part(trim(regexp_split_to_table(option_value, ';')), ':', 2) FROM vdc_options WHERE option_name = 'ServerCPUList' AND version = '3.5';\"" gives you a nice list of supported cpu names (the database name must be exact, so it's better to paste from that list. Intel Conroe Family Intel Penryn Family Intel Nehalem Family Intel Westmere Family Intel SandyBridge Family Intel Haswell-noTSX Family Intel Haswell Family Intel Broadwell-noTSX Family Intel Broadwell Family AMD Opteron G1 AMD Opteron G2 AMD Opteron G3 AMD Opteron G4 AMD Opteron G5 IBM POWER8 Then you can update the cluster directly: $ su - postgres -c "psql -t engine -c \"UPDATE cluster SET cpu_name = 'YOUR CPU NAME' WHERE name = 'YOUR CLUSTER NAME';\"" ('YOUR CPU NAME' and 'YOUR CLUSTER NAME' must of course correspond to the cpu name from the list above and the name of the cluster respectively) Also, could you open a bug on this? I think we should be able to do change the CPU type without all this. Thanks, mpolednik
