Yeah,it doesn't expose. so i write a new api to implements suspend method.
So i add some files as belows:
api/src/org/apache/cloudstack/api/command/user/vm/PauseVMCmd.java
@APICommand(name = "pauseVirtualMachine", description="Pause a virtual
machine.", responseObject=SuccessResponse.class)
public class PauseVMCmd extends BaseAsyncCmd {
public static final Logger s_logger =
Logger.getLogger(PauseVMCmd.class.getName());
private static final String s_name = "pausevirtualmachineresponse";
@Parameter(name=ApiConstants.ID, type=CommandType.UUID,
required=true, description="The ID of the virtual machine")
private Long id;
public Long getId() {
return id;
}
@Override
public String getCommandName() {
return s_name;
}
@Override
public long getEntityOwnerId() {
UserVm vm = _responseGenerator.findUserVmById(getId());
if (vm != null) {
return vm.getAccountId();
}
return Account.ACCOUNT_ID_SYSTEM; // no account info given, parent
this command to SYSTEM so ERROR events are tracked
}
@Override
public String getEventType() {
return EventTypes.EVENT_VM_PAUSE;
}
@Override
public String getEventDescription() {
return "Pausing user vm: " + getId();
}
public AsyncJob.Type getInstanceType() {
return AsyncJob.Type.VirtualMachine;
}
public Long getInstanceId() {
return getId();
}
@Override
public void execute() throws ResourceUnavailableException,
InsufficientCapacityException{
UserContext.current().setEventDetails("Vm Id: "+getId());
Boolean result;
result = _userVmService.pauseVirtualMachine(getEntityOwnerId(),
getInstanceId());
if (result !=null){
} else {
throw new ServerApiException(ApiErrorCode.INTERNAL_ERROR,
"Failed to pause vm instance");
}
}
}
And then add "
pauseVirtualMachine=15"
into
commands.properties
and
core/src/com/cloud/agent/api/PauseAnswer.java
core/src/com/cloud/agent/api/PauseCommand.java
aslo it's implements in related files.
When Calling api
http://192.168.129.7:8080/client/api?command=pauseVirtualMachine&id=605258c5-d9ef-45fe-9ea2-554a52ce7696&response=json&sessionkey=XGVvGrHvnEXbcAWa0DFjn%2Fq2eQQ%3D&_=1394674930344
it's return in browser "
{ "pausevirtualmachineresponse" :
{"uuidList":[],"errorcode":530,"cserrorcode":9999} }
" ,and NPE showed in log file:
