Cannot Start VM Because VirtualBox Thinks It is Read-Only

[Stewart Berman]

VirtualBox cannot start a VM because it thinks the vdi file is read only. Retrying startup eventually works. The problem is not consistent. One day it is one VM and the next day it happens with a different one.

Please note that although VirtualBox is at 3.1.2 the guest additions are at 1.4 although the problem did not start immediately after the guest additions were updated.

There are two log files attached -- one for the last failure today and one for the successfull startup.
