This application relates to apparatus and methods for booting servers, such as cloud datacenter compute servers. The servers may execute one or more hypervisors, such as stateless hypervisors, with each hypervisor supporting one or more virtual machines. In some examples, each of a plurality of servers are configured to boot from a network. The compute servers may obtain an IP address identifying a location of hypervisor bootable images. Upon a reboot, the servers may request and obtain a hypervisor bootable image from the IP address. The servers may execute the hypervisor bootable image to run a hypervisor. In some examples, the servers also obtain virtual machine images from the network. One or more hypervisors executing on each server may obtain, and execute, one or more of the virtual machine images to run one or more virtual machines.

A device startup method, apparatus, and system are disclosed, in which a host computer and a data processing unit (DPU) are connected via a computer bus. The method includes: before the DPU starts its operating system, the host writes a startup file to a first address of the DPU, where the first address is an address allocated by the host to the DPU's base address register (bar space); the DPU receives the startup file and writes it to a startup file area mapped to the first address; the DPU starts its operating system by loading the startup file from the startup file area. Compared to starting the DPU via network boot, this method eliminates the need for an additional network port on the DPU's BMI chip, and in some cases, even eliminates the need for a BMI chip altogether, thus reducing hardware costs. At the software level, the DPU does not require complex network configuration before starting the operating system, simplifying the DPU startup process.
