Partition Identifiers

A partition identifier is a 64-bit number allocated by the hypervisor. The hypervisor guarantees that all partitions will have unique identifiers within a single power cycle. However, partition identifiers are not globally unique; that is, identical identifiers might be generated across power cycles (in other words, reboots of the hypervisor).

The hypervisor defines the partition identifier data type as follows:

typedef UINT64 HV_PARTITION_ID, *PHV_PARTITION_ID;

A guest operating system should not assign any meaning to the value of a partition identifier.

The following invalid partition identifier is used in several functions to indicate an invalid partition.

#define HV_PARTITION_ID_INVALID 0x0000000000000000UI64
