Ubuntu VM - moved from Win8.1 to Ubuntu - kills everything

[j13ag0]

I created an Ubuntu 14.04 VM on a Windows 8.1 host using VBox 5.0.4.
Now I would like to use that same VM, but now on an Ubuntu 14.04 host.

I copied the entire folder containing the VM and used the Machine : Add menu item in VBox 5.0.12 on Ubuntu [host] to load the VM.
It starts fine, but shortly thereafter hangs the whole setup. The Ubuntu host is completely frozen.

Has anyone seen this ?
Got any suggestions ?

I'm currently trying a version of the VM with Guest Additions uninstalled to see if that makes a difference.

Please read the following: Minimum information needed for assistance. As far as the "VBox.log.zip" goes, here's what you do:
- Start the VM.
- Observe the error.
- Shut down the VM (if it hasn't aborted by itself).
- Right-click on the VM in the VirtualBox Manager.
- Select "Show Log..."
- Save it, ZIP it and attach it in your response.

Per your instructions, zipped log is attached here.

- Shut down the VM (if it hasn't aborted by itself).

You didn't shut down the VM, and as a result the VM log was incomplete. But I didn't see anything weird so far. Please try again, but this time shut down the VM before posting the log.

I think we're at an impasse.
With this problem when the VM freezes the host system freezes as well. There's no way to shut down the VM - everything is toast.

OK, I took a second look at your log, but with the same results; nothing. A couple of things you could try is to a) lower the RAM requirements to something like 2 GB and b) disable the 3D acceleration. Not that I would tell you in other cases, I'm just shooting in the dark here...

00:00:03.901007 The shared folder setup will not be complete. It is recommended to power down the virtual machine and fix the shared folder settings while the machine is not running"

I would do what the warning suggest first.

1) What is the difference in the two hosts in regard to the CPU?
2) As a test, can you install a new Ubuntu 14.04 on this host and does it work?

In response to Perryg:

1. The two hosts are the same machine. When the VM was first created, the machine was dedicated to Windows 8.1. Subsequently, I've set up a multiple HDD dual boot arrangement, where one drive contains the original Windows 8.1 install and the other contains the new Ubuntu 14.04 LTS setup.

2. Start over with the Ubuntu installation ? I'm afraid I don't have the time to do that. Its been a reliable setup in every respect except for this problem.

1. I believe what Perry was saying is fix the Shared Folder error first. I.E. remove it from the guest. You can always re-add it.
2. I believe he was saying try a new guest as a test, Not to replace the one you have or start over.

Replying to socratis:

I changed the settings on the VM to:
- memory: 2 GB
- 3D acceleration: OFF

Now the machine appears to operate without the problems noted in the original post.
This will allow me to continue to refer to this machine as I continue my work on another box.

Thanks for your assistance.

As I said, I was shooting in the dark, mainly for places that could cause problems between the two hosts, a) the graphics driver and b) the high amount of RAM allocated to a single process. Glad it worked...
