Well, I guess the subject line says it all. The guest boots apparently normally under VB4.3.12, but crashes on boot under 4.3.14. When I try to boot it, it gets past the initial VirtualBox screen, moving on to a blank black screen, which disappears after about ten seconds, after which the machine shows in the Virtual Manager panel as ‘aborted’. Reverting to 4.3.12 allows it to boot again.

I think the problem may relate to the way I have the disks set up. The system disk is a normal vdi file. However the /home partition is on a separate writethrough VMDK. I do it this way so that the home directories can be shared with a directly-booted Ubuntu system that I sometimes run on the mac. It seems to be this partition which is causing the problem. Any suggestions on how to fix this would be great.

The first obviously worrying thing I see in the logs is

Code: Select all

00:00:00.736248 VMSetError: /Users/vbox/tinderbox/4.3-mac-rel/src/VBox/Storage/VD.cpp(5949) int VDOpen(VBOXHDD*, const char*, const char*, unsigned int, VDINTERFACE*); rc=VERR_NOT_SUPPORTED
00:00:00.736268 VMSetError: VD: error VERR_NOT_SUPPORTED opening image file '/Volumes/VB/VMDKs/pv_extra.vmdk'

This occurs in both successful (4.3.12) boots and unsuccessful (4.3.14) ones. However in both cases, the boot continues.

In the unsuccessful (4.3.14) boots, the last material I see in the logs is:

In the successful boots, I see

further read attempts continue for quite a few lines, but in the end the boot continues on and succeeds.

IMHO your "successful" boots are telling: those are error messages saying that the disk image has been truncated. Did you recently transport it? Say on a FATx medium with its 4GB file size limit?

What do you mean by a "Writethrough VMDK"? I suspect you might be talking about raw disk access? VBox does support something called writethrough as well, but it's something else entirely.

Incidentally, we prefer complete logs here (as zip attachments). Let us be the judge of which lines are significant.
