#12737 fixed Cannot restore machine state for Win7 guest when using 3D acceleration 3vi1J
Description

I've had a Win7 guest VM that I'm running under a Linux host (Ubuntu). Saving and restoring the guest machine state for this VM worked fine in 4.2, but has not worked since the first 4.3 release, even though I am working with brand new 4.3 save states.

I can start the VM from scratch (no saved session) and it will run fine. I can save the session/state, and it exits normally. But, when I try to restore a saved session, "Restoring Virtual Machine" halts at around 93% and I immediately get a VirtualBox popup that says:


Failed to open a session for the virtual machine Win7.

No error info.

Result Code: NS_ERROR_CALL_FAILED (0x800706BE) Component: ProgressProxy Interface: IProgress {c20238e4-3221-4d3f-8891-81ce92d9f913}


At that point, the machine shows as "Aborted", and restarting it reboots it from scratch.

Now for the interesting part: If I disable 3D acceleration in the VirtualBox display options for the machine, I can save and restore the state with no problem. When enabled, 3D acceleration works fine (the machine does have the latest guest utils/drivers installed), and I was using it when I was save/restoring under 4.2 with no issue.

I'm not sure why having 3D acceleration makes any difference. I've tried restoring the machine both with my native HD4000 graphics and my nvidia 670MX chipset (via bumblebee) and get the same results. As I said, 3D acceleration works fine within the guest (as do my many other native 3D apps).

I am attaching the log. Please let me know any other info you require to help troubleshoot this persistent issue. I've looked around the forums/bugs, but have been unable to locate someone with this specific problem.

#8414 duplicate Cannot restore snapshot with USB pack uninstalled romkyns
Description

If the Extras pack is not installed, it is perfectly possible to START a VM that has USB configured. It warns that USB will actually be disabled, and gets on with it. Everything works fine.

If you then make a snapshot and try to restore it, it will say that USB is enabled but not installed, and hence the snapshot cannot be restored. I haven't found a way to convince VirtualBox to disregard USB, so for now it's a snapshot-loss bug, which is quite serious.

"Implementation of the USB 2.0 controller not found!"

#1601 fixed Cannot rewrite files in a shared folder -> please retry with 1.6.0 stanley
Description

Running 1.5.4 with Ubuntu 8 guest on Windows XP host. When I use gedit to change a textfile in the shared folder, I can access it but not save the file. It does not matter if I do sudo gedit or not.

Syslog says:

vboxvfs: sf_rename vboxCallRename failed rc=-114

There is no problem adding new files to the shared folder, or copying them out of it.
