Hypercall Restrictions

Hypercalls have restrictions associated with them that enable hypercalls to perform correctly. If all restrictions are not met, the hypercall will terminate with an appropriate error. The Remarks section of each hypercall reference page will list one or more of the following restrictions, if any apply:

  • The calling partition must have a particular privilege flag (for information about privilege flags, see the HV_PARTITION_PRIVILEGE_MASK union).

  • The calling partition must have been created by using a particular creation flag (for information about creation flags, see Partition Creation Flags).

  • The partition being acted upon must be in a particular state (for information about partition states, see Partition State).

  • The partition must be the root partition.

  • The partition must be either a parent or child partition.

  • The virtual processor must be in a particular state (for information about virtual processor states, see Virtual Processor States).
