Ubuntu 12.04 always crashes in Mac OS X host

[tpot]

Hi there. I've been using Vagrant on Mac OS X but recently VMs have been crashing consistently after boot.

Mac OS 10.8.3 Vagrant 1.0.7 Guest OS Ubuntu precise

Output from Vagrant is

$ vagrant up [default] VM already created. Booting if it's not already running... [default] Clearing any previously set forwarded ports... [default] Forwarding ports... [default] -- 22 => 2222 (adapter 1) [default] Creating shared folders metadata... [default] Clearing any previously set network interfaces... [default] Booting VM... [default] Waiting for VM to boot. This can take a few minutes. The VM failed to remain in the "running" state while attempting to boot. This is normally caused by a misconfiguration or host system incompatibilities. Please open the VirtualBox GUI and attempt to boot the virtual machine manually to get a more informative error message.

Booting with the GUI shows the OS booting up fully to a console prompt but VirtualBox crashes shortly after that, maybe less than a second.

This ticket looks like an existing ticket, https://www.virtualbox.org/ticket/11649, in that the crash occurs in the NAT thread. I'm in the process of uploading a core dump to appsdev/incoming on ftp.oracle.com called issue11811core.tar.gz.

Did you really upload the core dump? I cannot find it. Could you upload it again?

No response, closing.
