#13938 worksforme Mac host: Virtualbox creates empty processes and prevents restart/shutdown Blownauratone
Description

Macbook Pro 2012, OS X 10.9 Mavericks, newest Vbox and extensions, Windows 7 VM

I've seen this issue talked about throughout the VB forums and elsewhere, and so far there has been no resolution. My particular problem with this issue comes from the fact that I am a documentation specialist, and so must work extensively with unfinished software and drivers, which create instabilities often—requiring restart.

When I try to restart, Virtualbox's processes will not quit and cannot be stopped by any method, GUI or command line. I am forced to hard-reset my computer, which creates a host of other problems and causes a constant need for system maintenance.

I hope very much that there is a resolution for this issue! I otherwise prefer Vbox to all other virtual machine solutions, and spread its gospel with all of my friends in tech.

#11044 fixed REGRESSION: Guest session count doesn't decrement => Fixed in SVN Blrfl
Description

On a RHEL 5.8 host and a guest running the same with Guest Additions 4.2.0, I am unable to execute programs on the guest more than 32 times:

VBoxManage guestcontrol foo execute /bin/true --username bar --password baz --wait-exit

On any run after 32, I get the following error:

VBoxManage: error: Maximum number of guest sessions (32) reached.

...and the following error in the guest's log:

00:01:16.254389 ERROR [COM]: aRC=VBOX_E_IPRT_ERROR (0x80bb0005) aIID={19c32350-0618-4ede-b0c3-2b4311bf0d9b} aComponent={Guest} aText={Maximum number of guest sessions (32) reached}, preserve=false

Observations:

  • The guest process runs to completion and VBoxManage exits on its own.
  • There is no trace of the process on the guest after it exits (as expected).
  • Whether or not the guest execution service is ready doesn't appear to make a difference. I can run it 32 times when the guest is first starting up (and get the expected "not ready" error), after it's up and running or any combination of both.
  • Shutting the guest down and restarting it resets the counter.

This worked fine in 4.1.4.

If you need additional information, please append it to this ticket and I'll provide it.

Thanks.

#13773 fixed VBoxManage startvm exits with success when there are errors Blrfl
Description

This is similar to closed ticket 9642 but has more-specific circumstances.

When starting a guest using VBoxManage, the program exits with success even if an error was encountered and the guest failed to start:

% VBoxManage --version
4.3.20r96996

% VBoxManage import vboxbug.ova --vsys 0 --vmname vboxbug

The log file for the guest doesn't say much interesting except at the very end, which seems to confirm that the exit code being passed through is one for success in spite of the failure:

00:00:00.157344 Power up failed (vrc=VINF_SUCCESS, rc=NS_ERROR_FAILURE (0X80004005))

Some other VBoxManage commands exit correctly, such as:

% VBoxManage startvm nosuchvm --type headless
VBoxManage: error: Could not find a registered machine named 'nosuchvm'
VBoxManage: error: Details: code VBOX_E_OBJECT_NOT_FOUND (0x80bb0001), component VirtualBox, interface IVirtualBox, callee nsISupports
VBoxManage: error: Context: "FindMachine(Bstr(pszVM).raw(), machine.asOutParam())" at line 575 of file VBoxManageMisc.cpp

% echo $?
1

This was tested hosts running Linux and OS X. The imported guest type is BSD, but that shouldn't matter since it never powers up.
