List VirtualBox VMs, filter them to find the one you need, start the VM

5 posts in this topic

#1 ·  Posted (edited)

I have many VMs from past projects that I know I'll have to revisit. VirtualBox can sort them alphabetically, but I have failed to keep a consistent naming system that keeps track of the OS, the language name and the project name. So when I need to look for the VM I used 6 months ago for French and a certain project under Windows 8 using the Oracle VirtualBox Manager, my eyes tend to start glazing... I came up with a solution, and created this simple script to get the list of VMs, display them in a listview, then have a filter where I can type the project name, or the language, or the OS. Only the VMs with a name that contain the filter string are displayed, and I can just select the VM I need from my script UI, and launch it.

It could have added a lot of bells and whistles, and I may add a few in the future. If someone uses this script and adds features, please share.

The code:

#include <ListViewConstants.au3>
#include <WindowsConstants.au3>
#Include <GuiListView.au3>
#include <guiconstantsex.au3>

#include <AutoItConstants.au3>

I get:

 

'C:Program' is not recognized as an internal or external command,

operable program or batch file.

 

When trying to Start VM using the button in GUI.

That's odd, since the command to start the VM is 

Run(@ComSpec & ' /K "' & $sFilePath & 'vboxmanage" startvm "' & $sCurVMSel & '"' etc

where the command is enclosed between double quotes. Yet from what you are saying, it looks like the quotes are missing.

My VM host OS is Windows 7, if that has any bearing.

Could you save the command string value, then try it from the command prompt, to see if you find the same problem?

I have access to a windows 2008 R1 VM server, and reproduced the problem there. After googling and tinkering, I updated the command to start the VM to this, and it works.

Local $iPID = Run(@ComSpec & ' /K ""' & $sFilePath & 'vboxmanage" startvm "' & $sCurVMSel & '""', $sFilePath, @SW_HIDE, $STDOUT_CHILD)

Please let me know if this resolves the issue for you.

Thanks rodent1, I can't test it at the moment but I believe it should solve the problem, the double quotes are what was needed when passing arguments with spaces in file path. I knew the answer offhand but wanted you to figure it out as it helps with developing debugging skills. :) much appreciated!
