Validation of desired software state image for hardware incompatibilities

1. A method of validating a desired image of a virtualization software and a firmware package to be installed in a host, said method comprising:

acquiring a bill of materials for the host that lists hardware devices of the host;

for each of the hardware devices, searching for firmware and a driver thereof in a hardware compatibility list (HCL);

for each driver included in the desired image of the virtualization software, that corresponds to one of the hardware devices, determining whether or not the driver is compatible according to the HCL;

for each firmware included in the firmware package, that corresponds to one of the hardware devices, determining whether or not the firmware is compatible according to the HCL; and

validating the desired image of the virtualization software and the firmware package to be installed in the host if each of the hardware devices is determined to have a compatible driver and a compatible firmware in the desired image of the virtualization software and the firmware package, respectively.

2. The method of claim 1 , further comprising:

in response to a user input, generating a software specification that specifies the desired image of the virtualization software and a desired version of the firmware package.

3. The method of claim 1 , wherein the HCL is implemented in a physical or virtual server running a verification service that performs the searching.

4. The method of claim 1 , wherein a driver included in the desired image of the virtualization software is compatible if a version of the driver is listed in the HCL, and firmware included in the firmware package is compatible if a version of the firmware is listed in the HCL.

5. The method of claim 1 , further comprising:

calculating a first hash of the bill of materials of the host and storing the first hash in a validation map; and

acquiring a bill of materials of another host and calculating a second hash of the bill of materials of said another host and validating the desired image of the virtualization software and the firmware package to be installed in said another host if the calculated second hash matches the first hash stored in the validation map.

6. A non-transitory computer readable medium comprising instructions that are executable in a processor for the processor to carry out a method of validating a desired image of a virtualization software and a firmware package to be installed in a host, said method comprising:

acquiring a bill of materials for the host that lists hardware devices of the host;

for each of the hardware devices, searching for firmware and a driver thereof in a hardware compatibility list (HCL);

for each driver included in the desired image of the virtualization software, that corresponds to one of the hardware devices, determining whether or not the driver is compatible according to the HCL;

for each firmware included in the firmware package, that corresponds to one of the hardware devices, determining whether or not the firmware is compatible according to the HCL; and

validating the desired image of the virtualization software and the firmware package to be installed in the host if each of the hardware devices is determined to have a compatible driver and a compatible firmware in the desired image of the virtualization software and the firmware package, respectively.

7. The non-transitory computer readable medium of claim 6 , wherein the method further comprises:

in response to a user input, generating a software specification that specifies the desired image of the virtualization software and a desired version of the firmware package.

8. The non-transitory computer readable medium of claim 6 , wherein the HCL is implemented in a physical or virtual server running a verification service that performs the searching.

9. The non-transitory computer readable medium of claim 6 , wherein a driver included in the desired image of the virtualization software is compatible driver if a version of the driver is listed in the HCL, and firmware included in the firmware package is compatible if a version of the firmware is listed in the HCL.

10. The non-transitory computer readable medium of claim 6 , wherein the method further comprises:

calculating a first hash of the bill of materials of the host and storing the first hash in a validation map; and

acquiring a bill of materials of another host and calculating a second hash of the bill of materials of said another host, and validating the desired image of the virtualization software and the firmware package to be installed in said another host if the calculated second hash matches the first hash stored in the validation map.

11. A computer system comprising a management server and a host in which virtualization software and firmware are to be installed or upgraded, wherein the management server includes a processor that is programmed to execute a method of validating a desired image of the virtualization software and a firmware package to be installed in the host, said method comprising:

acquiring a bill of materials for the host that lists hardware devices of the host;

for each of the hardware devices, searching for firmware and a driver thereof in a hardware compatibility list (HCL);

for each driver included in the desired image of the virtualization software, that corresponds to one of the hardware devices, determining whether or not the driver is compatible according to the HCL;

for each firmware included in the firmware package, that corresponds to one of the hardware devices, determining whether or not the firmware is compatible according to the HCL; and

validating the desired image of the virtualization software and the firmware package to be installed in the host if each of the hardware devices is determined to have a compatible driver and a compatible firmware in the desired image of the virtualization software and the firmware package, respectively.

12. The computer system of claim 11 , wherein the method further comprises:

in response to a user input, generating a software specification that specifies the desired image of the virtualization software and a desired version of the firmware package.

13. The computer system of claim 11 , wherein the HCL is implemented in a physical or virtual server running a verification service that performs the searching.

14. The computer system of claim 11 , wherein a driver included in the desired image of the virtualization software is compatible if a version of the driver is listed in the HCL, and firmware included in the firmware package is compatible if a version of the firmware is listed in the HCL.

15. The computer system of claim 11 , wherein the method further comprises:

calculating a first hash of the bill of materials of the host and storing the first hash in a validation map; and

acquiring a bill of materials of another host and calculating a second hash of the bill of materials of said another host, and validating the desired image of the virtualization software and the firmware package to be installed in said another host if the calculated second hash matches the first hash stored in the validation map.
