How it works...

In step 1, we started a new QEMU instance with KVM acceleration and enabled a VNC server on it with the specified IP address and display port. We specified the amount of available memory and the CPU model name.

In step 4, we logged in the instance using the root user and the password we created when building the image, then obtained the CPU information by running the lscpu command. Note how the CPU model name matches what we specified with the -cpu flag when we started the virtual machine. Next, we checked the allocated memory with the free command, which also matches what we previously specified with the -m parameter.
