You do not check for guest additions capabilities and is most likely why it fails: your timing might not be right.
See the
code sample for the high-level steps. Adapt to your version.

My solution, for anyone who comes looking.
Code: Select all
import vboxapi
from time import time
SOURCE_PATH = r"K:\Downloads\first.sh"
DEST_PATH = r"/home/myuser/Downloads/first.sh"
UNAME = "myuser"
PASSWD = "mypass"
MACH_NAME = "Test"
virtualBoxManager = vboxapi.VirtualBoxManager(None, None)
try:
vbox = virtualBoxManager.getVirtualBox()
todo = vbox.findMachine(MACH_NAME)
alreadyRunning = todo.state is not virtualBoxManager.constants.MachineState_PoweredOff
print("Machine ", "started" if alreadyRunning else "starting")
session = virtualBoxManager.getSessionObject(vbox)
if not alreadyRunning:
progress = todo.launchVMProcess(session, "headless", None)
else:
todo.lockMachine(session, virtualBoxManager.constants.LockType_Shared)
try:
if not alreadyRunning:
progress.waitForCompletion(-1)
if progress.resultCode is not 0:
raise Exception("Machine failed to start: ",
progress.errorInfo.text)
print("Machine locked")
start = time()
while session.console.guest.additionsRunLevel is not virtualBoxManager.constants.AdditionsRunLevelType_Userland and time() - start < 180:
pass
if not time() - start < 180:
raise Exception("OS took too long to load")
print("OS loaded in ", time() - start, "sec")
runner = session.console.guest.createSession(UNAME, PASSWD, None, None)
try:
print("Session created")
runner.waitFor(
virtualBoxManager.constants.GuestSessionWaitForFlag_Start, 30 * 1000)
if runner.status is not virtualBoxManager.constants.GuestSessionStatus_Started:
raise Exception(
"Guest session did not start after ", 30, " sec")
copy = runner.fileCopyToGuest(SOURCE_PATH, DEST_PATH, None)
copy.waitForCompletion(-1)
if not runner.fileExists(DEST_PATH, False):
raise Exception("Copying failed")
except Exception as err:
print(str(err))
finally:
runner.close()
session.console.powerButton()
except Exception as err:
print(str(err))
finally:
session.unlockMachine()
finally:
print('Done')
