Methods and devices for provisioning a hyper-converged infrastructure of bare metal systems are disclosed herein. Two fabric elements are configured in a master-slave arrangement to ensure high availability. ONIE capable fabric elements may be pre-installed with an operating system as firmware to run open network operating systems, such as Linux. The Linux operating system includes a KVM hypervisor to run virtual machines. An operating system of the virtual machines can access an external network by creating a bridge between switch management ports and a virtual network interface. New node elements may be added by connecting the network ports of the new node element to the fabric elements and booting the new node element in a network/PXE boot mode. The new node element obtains an IP address from a DHCP server and boots an image downloaded from a PXE server.
