VM INSTRUCTION ERROR NUMBERS

For certain error conditions, the VM-instruction error field is loaded with an error number to indicate the source of 
the error. Table 30-1 lists VM-instruction error numbers.

NOTES:

a. Earlier versions of this manual described this error as “VMRESUME with a corrupted VMCS”.

7

VM entry with invalid control field(s)

b,c

b. VM-entry checks on control fields and host-state fields may be performed in any order. Thus, an indication by error number of one 

cause does not imply that there are not also other errors. Different processors may give different error numbers for the same VMCS.

c. Error number 7 is not used for VM entries that return from SMM that fail due to invalid VM-execution control fields in the executive 

VMCS. Error number 25 is used for these cases.
