如何使用python从虚拟机读取文件

Question

I'm running a virtual machine on my system using Oracle VirtualBox , what i'm trying to accomplish is to read file on virtual machine from my physical system . i'm using virtualbox api (pyvbox) to interface with VirtualBox . This the first time i'm using a virtualbox api.

UPDATE

>>> import virtualbox
>>> vbox = virtualbox.VirtualBox()
>>> vm =vbox.find_machine("XPBox")
>>> session = vm.create_session()
>>> gs = session.console.guest.create_session('xphandler' , ' qwerty')
>>> process, stdout, stderr = gs.execute('C:\\Windows\\System32\\cmd.exe', ['/C', 'tasklist'])

Traceback (most recent call last):
  File "<pyshell#29>", line 1, in <module>
    process, stdout, stderr = gs.execute('C:\\Windows\\System32\\cmd.exe', ['/C', 'tasklist'])
  File "C:\Python27\lib\site-packages\virtualbox\library_ext\guest_session.py", line 54, in execute
    process.wait_for(int(library.ProcessWaitResult.start), 0)
  File "C:\Python27\lib\site-packages\virtualbox\library.py", line 13666, in wait_for
    reason = ProcessWaitResult(reason)
  File "C:\Python27\lib\site-packages\virtualbox\library.py", line 121, in __init__
    raise ValueError("Can not find enumeration where value=%s" % value)
ValueError: Can not find enumeration where value=None
>>> 

This is the output when i type the below given solution.

Answer 1

Read the pyvbox documentation carefully. I believe you can figure out some solution. The given below example from the doc is not what you want but a good reference to start up.

ipython

In [1]: import virtualbox

In [2]: vbox = virtualbox.VirtualBox()

In [3]: vm = vbox.find_machine('test_vm')

In [4]: session = vm.create_session()

In [5]: gs = session.console.guest.create_session('Name', 'password')

In [6]: process, stdout, stderr = gs.execute('C:\\Windows\\System32\\cmd.exe', ['/C', 'tasklist'])

In [7]: print stdout

Answer 2

Here is an example on how to copy from a guest VM: https://gist.github.com/mjdorma/9044686

The traceback you posted seems to happen to a number of users. It occurs when IProcess.wait_for returns None. The library attempts to enumerate what type of ProcessWaitResult has been returned. This happens when vboxapi returns None from an attempted call to the IProcess.wait_for COM interface.

 In [5]: virtualbox.library.IProcess.wait_for?
Type:       instancemethod
String Form:<unbound method IProcess.wait_for>
File:       virtualbox\library.py
Definition: virtualbox.library.IProcess.wait_for(self, wait_for, timeout_ms)
Docstring:
Waits for one or more events to happen.

in wait_for of type int
    Specifies what to wait for;
    see <link to="ProcessWaitForFlag"/> for more information.

in timeout_ms of type int
    Timeout (in ms) to wait for the operation to complete.
    Pass 0 for an infinite timeout.

return reason of type ProcessWaitResult
    The overall wait result;
    see <link to="ProcessWaitResult"/> for more information.

Tip: Ensure you are running the latest virtualbox release when operating pyvbox.
