VirtualBox import error Cannot register the DVD image

virtualbox

I'm running v 4.2.6.
Starting this morning, I can't import some VMs, and some of my existing VMs are showing up as inaccessible and have the following error showing in the UI,

The same error too when i took the vm to another PC and try to open it with virtual box (v 5.0.10):

Cannot register the DVD image

'C:\Program
Files\Oracle\VirtualBox\VBoxGuestAdditions.iso'
{f5022f2e-0adc-4767-879d-65058a5578c5} because a CD/DVD image

'C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso' with UUID
{fc087cbc-df04-47b4-b42f-25f614463f78} already exists. Result Code:
E_INVALIDARG (0x80070057) Component: VirtualBox Interface:
IVirtualBox {3b2f08eb-b810-4715-bee0-bb06b9880ad2}

I solved it by open the file win 7 64.vbox with text editor and remove the tag:

<DVDImages>
   <Image uuid="{fd686a98-c1a6-42d9-82aa-67728b524d53}" location="C:/Program Files/Oracle/VirtualBox/VBoxGuestAdditions.iso"/>
</DVDImages>

Know that by removing the tag it will be added as empty tag. and reopent the vm of virtual box again. and it worked

Python – Elegant pattern for mutually exclusive keyword args

How about using something like a command dispatch pattern:

def funct(objnameOrType):
   dispatcher = {str: getObjByName,
                 type1: getObjByType1,
                 type2: getObjByType2}
   t = type(objnameOrType)
   obj = dispatcher[t](objnameOrType)
   doStuffWithObj(obj)

where type1,type2, etc are actual python types (e.g. int, float, etc).

VT-x is disabled in the BIOS for both all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED)

It is a RAM related issue. The documentation is self explanatory:

You are trying to allocate >3GB of RAM to the VM. This requires: (a) a 64 bit host system; and (b) true hardware pass-through ie VT-x.

Fast solution

Allocate less than 3GB for the virtual machine.

Complete solution

Make sure your system is 64 bit.
Enable virtualisation in your host machine. You can find how to do it here or there are many other resources available on Google.
