VERR_CFGM_NODE_EXISTS Error When Exporting than Importing Appliances on VirtualBox 5 => fixed in SVN/5.0.x

[Andy Sayler]

Whenever I export a VM from VirtualBox 5, and then import it via VirtualBox 5, I get the following error when I try to boot the newly imported VM:

--- A new node couldn't be inserted because one with the same name exists. (VERR_CFGM_NODE_EXISTS).

Result Code: NS_ERROR_FAILURE (0x80004005) Component: ConsoleWrap Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed} ---

I have confirmed the issue on the following systems:

Ubuntu 14.04 w/ VirtualBox 5.0 Ubuntu 15.04 w/ VirtualBox 5.0.2r102096 Windows 10 w/ VirtualBox 5.0.2r102096

I have also confirmed it with a range of guest and dummy (e.g. no loaded OS VMs). Importing VMs created in VirtualBox 4.X still works fine. So it seems to be a problem in the VirtualBox 5 export code. Currently, I am unable to create a working export using VirtualBox 5.

I've attached the log from two of the failure, but as I mention above, this happens regardless of the type/size/OS of VM I am exporting. I'll also try to attach a copy of one of the broken ova exports.

Issues also occurs on Windows 10 w/ Virtualbox 5.0.3r102166

Exporting the same VMs from VirtualBox 4.3 and then importing them into VirtualBox 5 works fine, so this definitely seems to be an isue with teh VirtualBox 5 export process.

Will be fixed in the next maintenance release, please try the latest testbuild from https://www.virtualbox.org/wiki/Testbuilds

workaround:

1. Open VirtualBox GUI
2. go to the the new VM (imported appliance)
3. select USB tab
4. disable USB
5. enable USB
6. start the new VM (imported appliance)

The error will still happen with appliances exported before the fix. You have to re export the VM with the fixed build in order to get rid of the error.

Closing this as duplicate of #14462 as it's the same issue.
