Bought a dedicated server. I would like to somehow make sure that it is really dedicated, and not a VPS.
Is there any algorithm?

hostnamectl

Chassis: container

If virtual, then there will be a Virtualization: item indicating the technology.

Generally, nested virtualization is not supported, although there are exceptions. The easiest way to check is to install virtualbox, create a virtual machine and run it.

In addition to the fact that they answered you correctly - measure it with a benchmark, for example, https://github.com/kdlucas/byte-unixbench . Also: cat /proc/cpuinfo
It doesn't really matter if it's physical or virtual, it's more important how much power it puts out. Some weak physical servers may be weaker than a good virtual machine.
