BecausethedeploymentrequestspecifiedpowerOn="true",thevAppispoweredonandreadyforusewhen
thetaskcompletes.Theclientcanwaitforasuitableintervalandcheckthetaskstatus(see“RetrieveaTask”
onpage 89),orsimplybeginrequestingoperationsonthepowered‐onvAppandchecking
thetaskstatusif
thoserequestsfail.See“DeployingandControllingvAppsandVirtualMachines”onpage 80.
Getting Information About the vApp
Asotherexampleshaveshown,aclientcanalwaysuseanHTTPGETrequesttodiscoverthecurrentstateof
anyvCloudobject,includingavApp.TheresponseinExample 2‐8revealsseveralthings:
 ThevAppisdeployed(itsdeployedattributeissettotrue)andpoweredon(status="4").
 TheVminitsChildrencollectionisalsopoweredonanddeployed.TheVmisconnectedtothevApp
networkcreatedduringinstantiation(seeExample 2‐6).Propertiesofthisnetworkareincludedinthe
NetworkConfigSectionofthevApp,thoughmostarenotshownhere.
 ActionlinksforalloperationsexceptpowerOnarepresentinboththevAppitselfanditschildVm.Because
thevAppisalreadypoweredon,thatoperationisinvalidforthevAppinitscurrentstate,sothelinkis
notpartoftheresponse.(Thelinkfordeployis
alwayspresent,eveninadeployedvApp,becausethe
deployactionisalwaysvalid.)TheVmelementalsoincludesseverallinksforactionsthatnotapplicable
toavApp:actionslikeacquiringascreenticketorthumbnail,andinsertingorremovingmedia,are
specifictoavirtualmachine.Otheractionslike
shutdownandreboot,canbeappliedtoeitherobject.See
“DeployingandControllingvAppsandVirtualMachines”onpage 80.
 Muchadditionalinformationisavailable,thoughmostofitisnotshownhere.Theexampledoesshow
wheretofindtheIPaddressofthevApp,intheIpAddresselementoftheNetworkConnection.
