Abstract
Techniques for recovering virtual machine state and boot information used to boot an installed guest operating system on systems where the information has either been lost or is not present are described.
Claims20
A computer system, comprising:
- circuitry for detecting, prior to booting a guest operating system, a path, stored in firmware, to a boot loader, wherein the boot loader is configured to load a guest operating system stored on a boot disk, wherein the guest operating system is configured to execute in a virtual machine;
- and
- circuitry for storing, prior to booting the guest operating system, the path to the boot loader on the boot disk.
A computer readable storage medium including executable instructions, the computer readable storage medium comprising:
- instructions for detecting virtual machine configuration information stored on a boot disk for a guest operating system prior to booting the guest operating system in a virtual machine;
- instructions for effectuating the virtual machine in accordance with at least a portion of the detected virtual machine configuration information;
- and
- instructions for booting the guest operating system in the virtual machine.
1 more element
A computerized method, comprising:
- detecting, prior to booting an operating system, configuration information stored on a boot disk for the operating system, wherein the configuration information describes a physical machine that effectuated the operating system;
- effectuating a virtual machine in accordance with at least a portion of the configuration information;
- and
- booting the operating system in the virtual machine as a guest operating system.
