Can start VM from snapshot

[Gutchi]

Hello,

I'm on debian jessie, i have a windows VM and this VM have 4 snapshots, when i restore the two older it run perfectly, but if i try to restore the two recent it failed and i have this error:

Code: Select all

ahci#0: The target VM is missing a device on port 0. Please make sure the source and target VMs have compatible storage configurations [ver=8 pass=final] (VERR_SSM_LOAD_CONFIG_MISMATCH).


Code d'erreur : 
NS_ERROR_FAILURE (0x80004005)
Composant : 
ConsoleWrap
Interface : 
IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

And in VM configuration the vdi disk is missing! Is there a solution to correct it?

Thank you!

The error has nothing to do with snapshots. Try discarding the saved state. (Right click VM, Discard saved state). In future you had best try to avoid updating VirtualBox while you have VMs (or snapshots of VMs) in saved states: it is saving the state of hardware which might change significantly in the next update.

I have do it, and the disk is still missing, so VM can't boot. I have some work on previous snapshoot, i someone know a way to not remove it...

One quick fix would be to:

• uninstall the version that you have now,
• download the previous version of VirtualBox (https://www.virtualbox.org/wiki/Download_Old_Builds),
• launch your VM,
• shut it down properly, i.e. not paused, not saved state, but complete shut down (remove any CDs that you might have before that) and
• update VirtualBox again.
