No worries about not being an admin.

To find a package that provides a certain tool, you can do this:

[root at rhel7-builder ~]# yum provides "*/lspci"
Loaded plugins: product-id, subscription-manager
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
rhel-7-server-rpms/7Server/x86_64/filelists_db

                                    | 3.7 kB  00:00:00
pciutils-3.2.1-4.el7.x86_64 : PCI bus related utilities
Repo        : rhel-7-server-rpms
Matched from:
Filename    : /usr/sbin/lspci

This shows that you can get 'lspci' by installing the 'pciutils' program.

As for "hardware", from inside the VM, only the emulated hardware can be 
seen, not the real hardware. So lspci, dmidecode and similar tools will 
report on the (virtual) hardware created by VMWare.

Sorry, but I can't provide any advice for VMWare, I use KVM.

Let me know if you have trouble.

Cheers!
