v4.2.18 Snapshot cannot be resumed - aRC=VBOX_E_OBJECT_NOT_FOUND - No storage device attached

[Jacob Klein]

Hello,

I use VirtualBox to do work on certain BOINC projects on my Windows 8.1 x64 host machine, but the 4.2.18 release appears to have a big problem, where it cannot resume a snapshot. I've heard of a couple projects that are reporting this same issue. This issue was not present in 4.2.16.

The main project I use is Test4Theory, and the administrators have created a news post advising their users to not use 4.2.18. I replied in that post, with details of the error I saw, based on my log file found in C:\Users\Jacob\.VirtualBox\VBoxSVC.log

The link to the news post is: ​http://lhcathome2.cern.ch/test4theory/forum_thread.php?id=1339

The link to the post (within that thread) where I report my findings is: ​http://lhcathome2.cern.ch/test4theory/forum_thread.php?id=1339&postid=15334#15334

I'll include the findings within this Bug Description (pasted below).

Could you please find out what causes this problem, and also, how to fix it?

Thanks, Jacob Klein

I too just realized I have the issue you are describing, with VirtualBox 4.2.18, where attempting to restore the snapshot will make the task crash.

Here is a snippet of my file: C:\Users\Jacob\.VirtualBox\VBoxSVC.log

... which shows that it gets in a loop trying to find the devices attached to the 'Floppy Controller' and 'Hard Disk Controller'

... and continually says: aRC=VBOX_E_OBJECT_NOT_FOUND (0x80bb0001)

... and then after about 5 minutes, gets: aRC=VBOX_E_INVALID_VM_STATE (0x80bb0002) aRC=VBOX_E_INVALID_VM_STATE (0x80bb0002) aRC=E_ACCESSDENIED (0x80070005)

... which results in a Computation Error.

Did anybody notify Oracle??

Note:

I'm not sure if the messages that say "aRC=VBOX_E_OBJECT_NOT_FOUND" and "No storage device attached" are relevant or not.

But, after 5 minutes of trying, the snapshot is still not resumed.

One of the Test4Theory moderators replied by saying:

As far as I investigated, the problem is caused during the phase of creating the snapshot. Both device controllers (disk and floppy) are saved in the snapshot, but not the related devices, hence restoring from the snapshot VirtualBox can't find the first device needed: harddisk. The wrapper keeps on trying until 5 minutes are over.

Similar problem here: I got an error _deleting_ a snapshot of a running machine:

Progress state: NS_ERROR_FAILURE
VBoxManage: error: Snapshot operation failed
VBoxManage: error: Medium

Next day, there's an error _taking_ a new snapshot:

Progress state: NS_ERROR_FAILURE
VBoxManage: error: Failed to take snapshot
VBoxManage: error: Assertion failed: [m->state == MediumState::LockedRead] at

Problem is: All disks of the snapshoted VM are gone (see attached sceenshot, VBox.png) and have to be reattached. This is a real no-go and I'll have to revert to 4.2.16 for the time beeing...

The errors I'm seeing in my Test4Theory logs read: "The target VM is missing a primary master device. Please make sure the source and target VMs have compatible storage configurations"
