I'm trying nproc and nproc --all in an OpenVZ container to count the number of CPU threads assigned to the vps by upstream provider. While nproc resulting 1, nproc --all resulting 24 CPU threads. May anyone please help me in explaining this?
The upstream provider is supposed to assign only one CPU and cat /proc/cpuinfo is also saying that. Then from where and how this 24 is coming?
Please find a screenshot here https://prnt.sc/hfzeuw. I'm using CentOS 7 inside the vps.

They are using a 12 core proc with hyperthreading, most likely. They have assigned one of these threads to your container.
From the man page:
nproc - print the number of processing units available
nproc [OPTION]...
--all print the number of installed processors`
Hope this helps!
EDIT:
What happens when you type the following:
[user@host]$ getconf _NPROCESSORS_ONLN
?

As anticipated it is showing the one (1) you have avail. Are you familiar with containers? If you'd like to learn more, I suggest reading: en.wikipedia.org/wiki/OpenVZ
