Same cpu seems to have different threads per core

Hi,

I have two servers from same provider with same specs but in different location.If you check the pastebin for the output of Iscpu the LA server has 2 threads per core but the LON one has only 1 thread per core.I also verified with other tools like htop

CPU : https://ark.intel.com/content/www/us/en/ark/products/97479/intel-xeon-processor-e3-1270-v6-8m-cache-3-80-ghz.html

Is the cpu dying or i am missing something here?

    Perhaps Hyper Threading is disabled on the London one?

    Edit: you could try grep -o '^flags\b.*: .*\bht\b' /proc/cpuinfo | tail -1 on each and see if the "ht" flag is set for one and not the other to double check.

    Maybe VT disabled on bios for another server.
