    PRL_UINT32 target_port, 
    PRL_CONST_STR target_session_id, 
    PRL_CONST_STR target_home_path,

File

Parameters

hVm

A handle of type PHT_VIRTUAL_MACHINE identifying the virtual machine.

target_host

The name of the target host machine.

target_port

The port number on the target host.

target_session_id

The target Virtuozzo Service session ID. This ID can be retrieved with PrlLoginResponse_GetSessionUuid from the response of the login request.

target_home_path

Target VM home path (i.e. where VM will be placed on target system). Empty string accounts as default VM directory path

migration_flags

Flags that specify migration type and etc. See acceptable flags at PrlCommandsFlags.h

reserved_flags

Reserved parameter for further purposes

force_operation

Specifies to process VM migration action without asking any additional questions from the Virtuozzo Service side (non-interactive clients should use this option).

Returns

A handle of type PHT_JOB containing the results of this asynchronous operation or PRL_INVALID_HANDLE if there's not enough memory to instantiate the job object.

Remarks

This is an extended version of PrlVm_Migrate function that allows to initiate VM migration process without active connection to target Virtuozzo Service.

To get the return code from the PHT_JOB object, use the PrlJob_GetRetCode function. Possible values are:

PRL_ERR_INVALID_ARG - invalid handle was passed.

PRL_ERR_SUCCESS - function completed successfully.
