C++ COM API IGuest->CreateSession/ProcessCreate

[syncovery]

I'm using C++ COM Vbox API and trying to Create guest session in virtual machine in order to be able to ProcessCreate in guest machine.

Code: Select all

Guest->CreateSession( SysAllocString(L"Administrator"), NULL, NULL, NULL, &GuestSession );

this call is always successful and GuestSession initialized.

BUT.

for some reason GuestSession->get_Status is always returns GuestSessionStatus_Error

IMHO because of that all the rest calls are unsuccessful.

I'm running on VBox 5.1.10 and I was trying to use VBoxGuestAdditions v4.3 as well as latest with no success.

when i call ProcessCreate in getting S_OK while there is no any evidence of created process in guest machine.

can somebody provide example of ProcessCreate ?

Please help to solve this issue. Thanks in advance.

Please have a look at these Java code samples, one of them is for running a guest process and reading its stdout which should be a good pointer.
In terms of API calls, the order and the flow, it is exactly the same in C++ so you can check your code and see if you didt forget something.

The example is for VBox 4.3 but the API calls did not change in 5.0 or 5.1, so the steps are exactly the same.

thank you for the examples, noteirak,
I don't see something special about CreateSession in Java code.
GuestSession->WaitFor( 1L, 30 * 1000, &aReason ); in my code exits immediately with aReason = GuestSessionWaitResult_None
I was trying to CreateSession by standard VboxManage.exe. and the problem still around WaitFor method.

Code: Select all

VBoxManage.exe: error: The specified user was not able to logon on guest
VBoxManage.exe: error: Details: code VBOX_E_IPRT_ERROR (0x80bb0005), component GuestSessionWrap, interface IGuestSession, callee IUnknown
VBoxManage.exe: error: Context: "WaitForArray(ComSafeArrayAsInParam(aSessionWaitFlags), 30 * 1000, &enmWaitResult)" at line 938 of file VBoxManageGuestCtrl.cpp

Can you install the matching guest additions (in terms of version) and post the output of the following command with the VM in the same state as if you would run the code (replace VMNAME):

Code: Select all

vboxmanage showvminfo VMNAME

Seems like they did not install or you didn't reboot the VM.
You should have somethinf similar to the following at and after the "Guest", around the end of the output.
The red parts are the mandatory requirements.

Guest:

Configured memory balloon size: 0 MB
OS type: Linux26_64
Additions run level: 2
Additions version: 4.3.28 r100309


Guest Facilities:

Facility "VirtualBox Base Driver": active/running (last update: 2016/12/28 08:55:26 UTC)
Facility "VirtualBox System Service": active/running (last update: 2016/12/28 08:55:32 UTC)
Facility "Seamless Mode": not active (last update: 2016/12/28 08:55:26 UTC)
Facility "Graphics Mode": not active (last update: 2016/12/28 08:55:26 UTC)

I will update the code sample later today to check for those requirements so the code can be fast-fail and provide a more meaningful troubleshooting.

Dear noteirak,
I have completely reinstall Guest OS and Guest additions with the same result - in the vboxmanage showvminfo results there is no
signs of Additions. I'm running VBox 5.1.10 and Guest Additions 5.1.10
Can you please tell what VBox version is workable?
Are there any settings to activate guest additions?
I do Device->Insert Guest Additions.iso - then starting installer from mounted CD and reboot. In OS Control Panel i can see Guest Additions Installed.



thanks in advance,
Happy New Year!

[noteirak]

Appologies for the delay, got caught up more than I thought in the new year celebrations.
I'll get back to you with the promised improved code sample later in the evening.

[noteirak]

So reading back on your feedback, it is clear that the issue lies somewhere during install/activation of the guest additions and not in your code calling the API.

Could you once again install the guest additions but doing it from the command line and adding the logging flag. So you should have the following command (slash L argument) after moving into the CD/DVD drive of the guest:

Code: Select all

VBoxWindowsAdditions.exe /l

You will find two log files into the install folder, C:\Program Files\Oracle\VirtualBox Guest Additions by default:
- install.log
- install_drivers.log

Please zip them and attach the zip file to this post (Upload attachment under the reply text area) so we can have a look.

[syncovery]

Dear Noreirac,
sorry for delays. Thank you for looking into the problem.
please see log files in attach.

[noteirak]

No error... and the plot thickens.

Can you restart the VM after install and then run the following command in an admin prompt and copy/paste the output please:

Code: Select all

sc query vboxservice

[syncovery]

sc query vboxservice output:

Code: Select all

SERVICE_NAME: vboxservice 
        TYPE               : 10  WIN32_OWN_PROCESS  
        STATE              : 4  RUNNING 
                                (STOPPABLE, NOT_PAUSABLE, ACCEPTS_SHUTDOWN)
        WIN32_EXIT_CODE    : 0  (0x0)
        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0

[noteirak]

After you started the VM and have confirmed the Guest Additions service is running in the guest (last command I gave you), please attach the following info (zip if too big):
- VBox.log located in the Logs subfolder of the VM folder
- Output of vboxmanage showvminfo VMNAME

[syncovery]

Max thank you for supporting!
in the attach are logs and screenshot of VM.

respectfully,

[noteirak]

I can't see any issue in the logs with the additions, so I'm quite baffled here I must say.
I'll bump this up to the devs and will let you know!

In the meantime, do you have any other VM you can check the output of vboxmanage on? Just to be sure it's not a global issue with your virtualbox installation.
