Hi, I'm trying to package util-linux for exherbo, a source based distro.
util-linux's lscpu tests fail when compiled on a VM running under a VMware Vsphere esxi hypervisor.

Hi Luis,
I have a hunch best way to proceed is to get cpu data from your /proc.
This can be achieved easiest by running a lscpu test data collector
script.
cd src/util-linux
sh tests/ts/lscpu/mk-input.sh vmware-esxi
After running the script you can find file vmware-esxi.tar.gz in
current directory. Please send the file to mail list, and inform if it
can be added to be part of regression test suite (which would of
course is much preferred).

Hi Sami,
Thanks for the reply. I include the output file from mk-input.sh, I have
to note that there were a three permission denied instances.
# sh tests/ts/lscpu/mk-input.sh vmware-esxi
cp: cannot open ‘/sys/devices/system/cpu/microcode/reload’ for reading:
Permission denied
cp: cannot open ‘/sys/devices/system/cpu/probe’ for reading: Permission
denied
cp: cannot open ‘/sys/devices/system/cpu/release’ for reading:
Permission denied
Feel free to use it as part of the regression test suite.

Oh, I did not look the code before asking the stuff from /proc/. It
seems the lscpu detects virtualization by looking characteristics of
cpu. See cpuid() from
https://github.com/karelzak/util-linux/blob/master/sys-utils/lscpu.c#L453
Perhaps turning off call to that function is the most sensible thing
to do. Any thoughts?

Thanks for the fix. After applying it I got these results:
lscpu: ...

Yes, good idea. Implemented, pushed.
