[FIXED] Failed to load unit 'hda' when restoring session

[jms-vbox]

VirtualBox VM 5.0.12 r104815 linux.amd64, latest guest additions installed
Host: LINUX_64BITS_UBUNTU_15_10, RAM 32GB
Guest: Windows 10 64bit, RAM 4GB

Couldn't find any information related to this issue. When I restore guest saved session it always ends with error, doesn't matter if other guest is running or not. This issue does not exist with other guest (Windows 7).

Restore error:

Code: Select all

Failed to open a session for the virtual machine Win10.

Failed to load unit 'hda' (VERR_SSM_LOADED_TOO_LITTLE).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I can start guest by discarding saved state and starting from beginning, but error will repeat every time when I try to restore. I think this started after update to 5.0.12 (from 5.0.10).
Should I file a bug or do you have any suggestions what could be wrong?

Got the same message, even after reinstalling Windows 10. Waiting for Oracle answer.

I have the same situation with restoring Windows ThinPC (actually it's Windows 7).

This is the full message:

Failed to load unit 'hda' (VERR_SSM_LOADED_TOO_LITTLE).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

VBox version is 5.0.12 r104815

Additional info

I've Discarded saved state, and rebooted the guest, then made several suspend/load cycles successfully. No errors occurred.
Before this failure occurred I suspended the guest having 4GB of RAM on my host, and resumed after adding additional 4GB. Could this have any connection to the error ?

The host is 64 bit Linux XUbuntu 14.04.03.

I am experiencing the same issue after upgrading to 5.0.12-104815. I am running Ubuntu 14.04 as the host OS and Windows 10 PRO (1511) as a guest.
I can suspend/resume before logging on, but after logging on suspend/resume always fails with this error. Perhaps it is related to the guest additions?

This has nothing to do with the Guest Additions. It's a bug in the saved state loading for the HDA device that's inadvertently incompatible with earlier versions.

What version of VirtualBox was the saved state created with? 5.0.10 or something older?

[gwiesenekker]

Hi,

The VM was created from scratch with version 5.0.12. You are correct that it has nothing to do with the guest additions, I uninstalled them and I still cannot resume, although the error message when resuming is different (VERR_SSM_STRUCTURE_MAGIC).
I upgraded VirtualBox from 5.0.10 to 5.0.12 on another Ubuntu host running 5.0.10 guests only (with 5.0.10 guest additions) and I cannot suspend/resume a Windows 10 PRO (1511) guest either (I am not resuming from a 5.0.10 saved state), so it looks like this bug was introduced in 5.0.12.

Hi,

It looks like this problem is not always reproducible: this morning I was facing it all the time, but this afternoon the problem is suddenly gone, both on the original host and the host that I upgraded to 5.0.12..

Hi,

Downgrading to 5.0.10 solves the issue for now. I uninstalled the 5.0.12 guest additions, uninstalled 5.0.12 using dpkg -P virtualbox-5.0, installed 5.0.10 and installed the 5.0.10 guest additions.

Regards,

I downgraded as suggested and got the same error message.

[nursoda]

Same issue here. Does anyone know where these cryptic error codes are explained?

[mpack]

They are explained by searching the source code. I doubt that they'll ever be formally documented: the devs need to be able to add and remove error checking as required, they don't need to be tied down to a somewhat relevant set of documented codes. If you can't read C++ source code then an explanation of the codes would likely be just as useless to you anyway.

Ran into the same thing myself this morning. Has an issue been logged for this? Is there a workaround?

[jms-vbox]

I created a ticket to Virtualbox's bugtracker: https://www.virtualbox.org/ticket/14981

[nursoda]

I only had this ONCE. Never happened again. Strange.

The saved state handling should be fixed since r104839. Please give these test builds a try:
