what is the next step

What Linux problems are you having?? It says you've installed the virtualization tools and they're up to date. What, exactly, are you expecting to have happen at this point? You've not shown us any errors, and we don't know what version of CentOS you're using. There are many guides you can find with a search for how to use KVM on CentOS...start with those, and post back if you have any problems.

VTx means the CPU supports virtualization. However, check the BIOS settings to make sure that it is not disabled at boot.

Question

have you even ran
to start the KVM ?

and are the required background services running ?

1) libvirt-guests
2) libvertd

and lastly have you read any user manuals on running and using KVM
then on installing a OS ( a qcow2 image )in the KVM
