Excecute command on guest os and get output on host

[t4ks]

Hi

Need help. I try execute command (cloning git repo) in guest machine from host and try get out put, but my solution doesn't work and I don't know why? because If I try exceute standart linux comand (ls -la) this working normal.
This my code:

Code: Select all

from vboxapi import VirtualBoxManager

BASIC_SNAPSHOT = 'clear'
TARGET_NAME = 'ubuntu-server-1404'


vbm = VirtualBoxManager()
vbox = vbm.vbox
mach = vbox.findMachine(TARGET_NAME)

session = vbm.getSessionObject(vbox)

def run_test():
    mach.lockMachine(session, 1)

    guest = session.console.guest
    # gs = session.console.guest.createSession('t4ks', 'Qwerty123', '', '')

    gs = guest.createSession('t4ks', 'Qwerty123', '', 'rungit')

    gs_state = gs.waitFor(vbm.constants.GuestSessionWaitForFlag_Start, 0)
    print gs_state

    #args = ["-l", "-a"]
    #gp = gs.processCreate('/bin/ls', args, [], [vbm.constants.ProcessCreateFlag_WaitForStdOut], 0)

    args = ["clone", "<Repo>", "<Some directory>"]
    gp = gs.processCreate('/usr/bin/git', args, [], [vbm.constants.ProcessCreateFlag_WaitForStdOut], 0)
    #IEventSource
    es = session.console.eventSource
    #IEventListener
    el = es.createListener()
    es.registerListener(el, [vbm.constants.VBoxEventType_Any], False)

    try:
        gp_res = gp.waitFor(vbm.constants.ProcessWaitForFlag_StdOut, 10000)
        print "Result status for wating guest process: ", gp_res
        keepLooping = True
        while keepLooping:
            # IEvent
            ev = es.getEvent(el, 200)
            if ev != '': #how check?
                es.eventProcessed(el, ev)

            stdOut = gp.read(1, 10000, 100)
            print stdOut
            print gp.status
            if gp.status == vbm.constants.ProcessStatus_TerminatedNormally or \
                            gp.status == vbm.constants.ProcessStatus_Terminating or \
                            gp.status == vbm.constants.ProcessStatus_TerminatedSignal or \
                            gp.status == vbm.constants.ProcessStatus_TerminatedAbnormally or \
                            gp.status == vbm.constants.ProcessStatus_TimedOutKilled or \
                            gp.status == vbm.constants.ProcessStatus_TimedOutAbnormally:
                keepLooping = False
        print "Process exit code: " , gp.exitCode
    finally:
        es.unregisterListener(el)
        if gp.status == vbm.constants.ProcessStatus_TerminatedNormally or \
            gp.status == vbm.constants.ProcessStatus_Terminating or \
            gp.status == vbm.constants.ProcessStatus_TerminatedSignal  or \
            gp.status == vbm.constants.ProcessStatus_TerminatedAbnormally or \
            gp.status == vbm.constants.ProcessStatus_TimedOutKilled or \
            gp.status == vbm.constants.ProcessStatus_TimedOutAbnormally:
            gp.terminate()

    #print gp.status
    #out = gp.read(1, 100000, 10000)
    #print out
    # gp.terminate()

    session.unlockMachine()

Thank's

Please show the output of your code, and stacktrace of error if you have one.

Please show the output of your code, and stacktrace of error if you have one.

This output if I run standart command ls -la

Code: Select all

    args = ["-l", "-a"]
    gp = gs.processCreate('/bin/ls', args, [], [vbm.constants.ProcessCreateFlag_WaitForStdOut], 0)

and disable "if" in "while" loop where check status code "gp.status" because statment never passed

Code: Select all

if gp.status == vbm.constants.ProcessStatus_TerminatedNormally or \
                            gp.status == vbm.constants.ProcessStatus_Terminating or \
                            gp.status == vbm.constants.ProcessStatus_TerminatedSignal or \
                            gp.status == vbm.constants.ProcessStatus_TerminatedAbnormally or \
                            gp.status == vbm.constants.ProcessStatus_TimedOutKilled or \
                            gp.status == vbm.constants.ProcessStatus_TimedOutAbnormally:

This out when I try call git:

In a while loop I checked event, but I think is wrong statement because variable "ev" saved object Library.Event and how check his empty or not I don't know

Code: Select all

ev = es.getEvent(el, 200)
            if ev != '':
                es.eventProcessed(el, ev)

Please show the output of your code, and stacktrace of error if you have one.

UPD:
I change my script, for see more output detaile.

This my code:

Code: Select all

def run_test():
    vbm = VirtualBoxManager()
    vbox = vbm.vbox
    session = vbm.getSessionObject(vbox)
    mach = vbox.findMachine(TARGET_NAME)
    try:
        mach.lockMachine(session, 1)

        console = session.console

        guest = console.guest
        # gs = session.console.guest.createSession('t4ks', 'Qwerty123', '', '')

        t = 50 * 1000

        gs = guest.createSession('t4ks', 'Qwerty123', '', 'rungit')

        gs_state_result = gs.waitForArray([vbm.constants.GuestSessionWaitForFlag_Start], t)
        print gs_state_result

        #args = ["-l", "-a"]
        #gp = gs.processCreate('/bin/ls', args, [], [vbm.constants.ProcessCreateFlag_WaitForStdOut], 0)

        args = ["clone", "<repo>", "/home/t4ks/pyteamcity"]
        gp = gs.processCreate('/usr/bin/git', args, None, [vbm.constants.ProcessCreateFlag_WaitForStdOut], t)
        gps = gs.processes

        for i in gps:
            gp_foo = i
            print "Arguments: ", gp_foo.arguments
            print "Ex path: ", gp_foo.executablePath
            print "PID: ", gp_foo.PID
            print "Status: " , gp_foo.status

        foo = []
        foo.append(vbm.constants.ProcessWaitForFlag_StdOut)

        waitResult = gp.waitForArray(foo, t)
        stdOut = gp.read(1, 10000, t)
        print stdOut
        if waitResult == vbm.constants.ProcessWaitResult_StdOut:
            print "Process Load finished"

    except:
        print traceback.format_exc()

now I see process info, but git output not steel working:

Great! I solved problem(not be sure what right). I added stdOut and errOut. And add in argument list args[] first element '/usr/lib/git' and it's working! WTF? =) How it can at be?

this my code:

    vbm = VirtualBoxManager()
    vbox = vbm.vbox
    session = vbm.getSessionObject(vbox)

        mach.lockMachine(session, 1)

        console = session.console

        guest = console.guest
        # gs = session.console.guest.createSession('t4ks', 'Qwerty123', '', '')

        t = 50 * 1000

        gs = guest.createSession('t4ks', 'Qwerty123', '', 'rungit')

        gs_state_result = gs.waitForArray([vbm.constants.GuestSessionWaitForFlag_Start], t)
        print gs_state_result

        args = ["/usr/bin/git", "clone", "<must be repo but I don't permission for this in this forum>" ,"/home/t4ks/pyteamcity"] #WTF
        gp = gs.processCreate('/usr/bin/git', args, None, [vbm.constants.ProcessCreateFlag_WaitForStdOut , vbm.constants.ProcessCreateFlag_WaitForStdErr], t)
        gps = gs.processes

        foo = []
        foo.append(vbm.constants.ProcessWaitForFlag_StdOut)
        foo.append(vbm.constants.ProcessCreateFlag_WaitForStdErr)

        waitResult = gp.waitForArray(foo, t)
        stdOut = gp.read(1, 10000, t)
        print "stdOut: ", stdOut
        stdErr = gp.read(2, 10000, t)
        print "stdErr: ", stdErr

    except:

----------------UPD3----------------

I try run this script in my ubuntu 14-04 host, but I get stacktrace

Code: Select all

Traceback (most recent call last):
  File "/home/administrator/PycharmProjects/vbautotest/run.py", line 85, in run_test
    gps = gs.processes
  File "/usr/lib/virtualbox/sdk/bindings/xpcom/python/xpcom/client/__init__.py", line 391, in __getattr__
    raise AttributeError("XPCOM component '%s' has no attribute '%s'" % (self._object_name_, attr))
AttributeError: XPCOM component '<unknown>' has no attribute 'processes'

I wrapped string "gps = gs.processes" try/except and pass this error. This is not critical error, but maybe have alternative atribute "proccess" for check all proccess when I run this script on linux based system?

P.S. Sorry for my english =)
