id,summary,reporter,owner,description,type,status,component,version,resolution,keywords,cc,guest,host 12160,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.
