4.3.2 PATM VERR_SSM_LOADED_TOO_MUCH when resuming from snapshot => Fixed in SVN

Reported by: Jacob Klein Owned by:

Keywords: PATM VERR_SSM_LOADED_TOO_MUCH Cc: Jacob_W_Klein@…
Guest type: Linux Host type: Windows

Description

I use BOINC on my Windows 8.1 x64 machine, to work on Test4Theory VM tasks (Linux 2.6 client VMs), and we're having a problem resuming snapshots.

Essentially, it looks like there's an error when PATM is loading, something about: !pSSM->u.Read.fEndOfData .... resulting in VERR_SSM_LOADED_TOO_MUCH

Log of error:

00:00:01.505325 AssertLogRel D:\tinderbox\win-4.3\src\VBox\VMM\VMMR3\SSM.cpp(6212) int __cdecl ssmR3DataReadBufferedV2(struct SSMHANDLE *,void *,unsigned __int64): !pSSM->u.Read.fEndOfData

00:00:01.505385 VMSetError: Failed to load unit 'PATM'

I'm positive we did not have this error in 4.2.16, and I'm pretty sure that my testing shows we did not have it in 4.2.18 or 4.3.0 either.

Did the 4.3.2 release break something here?

Here's a little more log detail, which might be helpful, including the final error message which said:

I believe it is possible that the solution for Ticket #12222 caused this ticket's problem.

I attached the full log, in case it gives any clues/hints as to the problem.

Also, the steps I use to replicate the problem are:

  • Set BOINC so that "Leave applications in memory while memory is suspended" (LAIM) is unchecked
  • Get a T4T task in BOINC
  • Let it run for 25 minutes
  • Open up Oracle VM VirtualBox Manager
  • Verify that the T4T VM has, on the snapshots tab, a snapshot that says 1200 (indicating that 2 snapshots were taken, the 10-minute mark and the 20-minute mark)
  • In BOINC, Activity -> Suspend
  • Wait 30 seconds
  • In BOINC, Activity -> Run based on preferences
  • See if Oracle VM VirtualBox Manager shows that the task restarted and is running
  • When it's not restarting properly, inspect the VBox.log file in the BOINC slot directory for that task

comment:4 by Jacob Klein, 10 years ago

I have made some progress in identifying the source of the problem!

T4T tasks run VMs of Type "Linux" and Version "Linux 2.6 / 3.x", with the hardware virtualization setting "Enable VT-x/AMD-V" UNCHECKED. If I check that "Enable VT-x/AMD-V" setting before the snapshot is taken, I am then able to restore the snapshot and start the VM without getting the PATM VERR_SSM_LOADED_TOO_MUCH error.

Are snapshots taken WITHOUT "Enable VT-x/AMD-V" being somehow corrupted?

Is VirtualBox somehow not able to load such snapshots?

For additional reference, the full VM description of the T4T task's VM, is below. Looking forward to your response.

Thanks, Jacob

Any word on when this issue (caused by resuming snapshots without the "Enable VT-x/AMD-V" feature enabled) ... will be looked at or resolved?

Now getting a new/different error resuming a non-VT-X BOINC Test4Theory snapshot.

The new error is:

Replying to frank:

Fix in 4.3.4.

I have 4.3.4-91027 installed on Windows 8 and have exactly this issue. I can't resume VM with Windows guest. It gives me this error "ERR_SSM_LOADED_TOO_MUCH". How can I fix this issue? I need access to my VM data.

The bug should be finally fixed in VBox 4.3.6. Please continue the discussion in #12414.
