I usually use VirtualBox with VNC and webservice on headless servers. I noticed that after any update if the VMs are not turned off but with saved state the new version of VirtualBox is unable to start them and the process terminates with an error. To start the VMs you should discard their states by running (as vboxusers if this is the user who runs VirtualBox services):
VBoxManage discardstate <vmname>
This is always necesarry in my case after almost any update of VirtualBox
P.S. Sorry I sent an reply yesterday but not to the mailing list...
