#8003 obsolete Cryptic and confusing error message during vboxmanage modifyvm --guestmemoryballoon Scott Brickey
Description

1) when setting guestmemoryballoon size, error messages are cryptic at best (I don't care about the DETAILS or CONTEXT) 2) when setting guestmemoryballoon size, maximum allowed value is rounded, causing confusion.


Step 1) try setting value of 2048MB

C:\Program Files\Oracle\VirtualBox>vboxmanage modifyvm "Domain Workstation" --guestmemoryballoon 2048 Oracle VM VirtualBox Command Line Management Interface Version 3.2.10 (C) 2005-2010 Oracle Corporation All rights reserved.

ERROR: Invalid memory balloon size: 2048 MB (must be in range [0, 1843] MB) Details: code E_INVALIDARG (0x80070057), component Machine, interface IMachine, callee IUnknown Context: "COMSETTER(MemoryBalloonSize)(ValueUnion.u32)" at line 1714 of file VBo xManageModifyVM.cpp

Ok, Step 2) try setting to stated maximum...

C:\Program Files\Oracle\VirtualBox>vboxmanage modifyvm "Domain Workstation" --guestmemoryballoon 1843 Oracle VM VirtualBox Command Line Management Interface Version 3.2.10 (C) 2005-2010 Oracle Corporation All rights reserved.

ERROR: Invalid memory balloon size: 1843 MB (must be in range [0, 1843] MB) Details: code E_INVALIDARG (0x80070057), component Machine, interface IMachine, callee IUnknown Context: "COMSETTER(MemoryBalloonSize)(ValueUnion.u32)" at line 1714 of file VBo xManageModifyVM.cpp

Ugh. Step 3) try setting just shy of stated maximum (assume rounding to be the cause)

C:\Program Files\Oracle\VirtualBox>vboxmanage modifyvm "Domain Workstation" --guestmemoryballoon 1842 Oracle VM VirtualBox Command Line Management Interface Version 3.2.10 (C) 2005-2010 Oracle Corporation All rights reserved.

C:\Program Files\Oracle\VirtualBox>

SUCCESS (finally)

PS: this feature (along with PageFusion) should be configurable within the UI... either by allowing multiple sliders in the memory page, or with another slider.

#8005 obsolete VBoxManage.exe crashes when unregistering a VM with no storage Justin R. Cutler
Description

It appears that attempting to unregister and delete a VM with no attached storage causes VBoxManage.exe to crash.

Steps to reproduce:

  1. Create and register an "empty" VM
    C:\Program Files\Oracle\VirtualBox>VBoxManage.exe createvm --name Test --register
    Virtual machine 'Test' is created and registered.
    UUID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
    Settings file: 'C:\Users\<username>\VirtualBox VMs\Test\Test.vbox'
    
  2. Attempt to unregister and delete the VM
    C:\Program Files\Oracle\VirtualBox>VBoxManage.exe unregistervm Test --delete
    VBoxManage.exe: error: Code RPC_E_SERVERFAULT (0x80010105) - The server threw an
     exception (extended info not available)
    Context: "Delete(ComSafeArrayAsInParam(aMedia), pProgress.asOutParam())" at line
     167 of file VBoxManageMisc.cpp
    

At this point, a crash dialog will pop up with the following text (Windows 7 x64 host):

VBoxManage.exe has stopped working

A problem caused the program to stop working
correctly. Please close the program.

 -> Close the program
#8016 obsolete VM will not shutdown or restart Don Seiler
Description

This has happened so far on two VMs. Both running Oracle Enterprise Linux 5.5 as guests. Both using second virtual SCSI disks for Oracle ASM.

When shutting down, the last thing I see in the guest console is "Synchronizing SCSI cache", and the vbox log is full of errors about taking screenshots. See attached for the vbox log.

The guest just hangs here until I manually kill the VirtualBox process for it.
