VirtualBox 4.3 - wrong hardwareuuid => Fixed in SVN

[www0815]

If you run the following command:

VBoxManage --nologo showinfo --machinereadable "YOUR MACHINE NAME" | grep 'hardwareuuid'

You get the following result:
with Version 4.2.18: hardwareuuid="30761f24-1e22-49c8-a4a5-dedc4a7ed74c" (or anything similar)
with Version 4.3: hardwareuuid="00000000-0000-0000-0000-000000000000"

This is very annoying, because lot's of scripts use the variable hardwareuuid to start or modify a virtual machine. But with such a hardwareuuid all scripts won't work anymore. Please correct this.

By the way: The following command doesn't have any effect in version 4.3:

VBoxManage modifyvm "YOUR MACHINE NAME" --hardwareuuid "30761f24-1e22-49c8-a4a5-dedc4a7ed74c"

The hardware uuid is after this command still full of zeros.

Possible Workaround:

if the uuid (from the Machine tag in the vbox file) is added to the Hardware tag, the VBoxManage tool works as desired.

e.g. Before

  <Machine uuid="{30761f24-1e22-49c8-a4a5-dedc4a7ed74c}" ...>
    ....
    <Hardware version="2">

After

  <Machine uuid="{30761f24-1e22-49c8-a4a5-dedc4a7ed74c}" ...>
    ....
    <Hardware version="2" uuid="{30761f24-1e22-49c8-a4a5-dedc4a7ed74c}">

That is a nice workaround. Thank you very much.

Could maybe anyone make a short comment here, when it is corrected in an upcoming maintenance release?

Thanks for the report! This bug will be fixed in the next maintenance release.

This workaround does not work for the issue of an invalid GUID for PXE boot as I described in https://www.virtualbox.org/ticket/12238
