Path Parameters
string
moId
Required

The unique identifier for the managed object to which the method attaches; the serialized managed object reference for a request has the form moType/moId, in this case HostSystem/{moId}.

string
release

Request Body
QueryMemoryOverheadRequestType of type(s) application/json
Required
{
    "memorySize": 0,
    "videoRamSize": 0,
    "numVcpus": 0
}
integer As int64 As int64
memorySize
Required

The amount of virtual system RAM, in bytes. For an existing virtual machine, this value can be found (in megabytes) as the memoryMB property of the VirtualHardware.

integer As int32 As int32
videoRamSize
Optional

The amount of virtual video RAM, in bytes. For an existing virtual machine on a host that supports advertising this property, this value can be found (in kilobytes) as the videoRamSizeInKB property of the VirtualMachineVideoCard. If this parameter is left unset, the default video RAM size for virtual machines on this host is assumed.

integer As int32 As int32
numVcpus
Required

The number of virtual CPUs. For an existing virtual machine, this value can be found as the numCPU property of the VirtualHardware.
