1. A method, comprising:
- defining, using a second computer, a virtual boot device, the virtual boot device having a boot image for a first computer having a memory and a physical boot device, the virtual boot device in communication with the first computer and the second computer;
subsequent to configuring the first computer, power cycling the first computer, and upon the power cycling, loading, by the first computer, the boot image from the virtual boot device to a software stack in the memory;
configuring, by the second computer, the first computer to boot from the virtual boot device;
wherein the second computer is configured to define the virtual boot device in response to detecting a failure of the first computer, and detecting the failure comprises the second computer conveying a request to the first computer and not receiving a response to the request; and
subsequent to booting the first computer from the virtual boot device, automatically reconfiguring, by the second computer, the first computer to boot from the physical boot device upon a subsequent power cycle, wherein the second computer reconfigures the first computer by reformatting the physical boot device of the first computer, reporting and repairing problems of the physical boot device encountered during the reformatting to the second computer, saving a factory default boot image to the physical boot device, and reconfiguring a basic input/output system (BIOS) of the first computer to switch from booting from the virtual boot device to the physical boot device of the first computer upon the subsequent power cycle.

Abstract
Methods, apparatus and computer program products implement embodiments of the present invention that enable a computer system comprising networked computers to self-heal from a boot failure of one of the computers. In some embodiments, upon detecting a first computer having a memory and a physical boot device failing to successfully load a boot image, a second computer defines a virtual boot device in communication with the first computer and the second computer and having a boot image for the first computer. Subsequent to defining the virtual boot device, the second computer can configure the first computer to boot from the virtual boot device.
