cannot resume saved state with 4.1.8

[Sam Morris]

I suspended my VM with 4.1.6, then upgraded to 4.1.8. Resuming the machine now fails with the following error:

Failed to open a session for the virtual machine leela.

Failed to load unit 'HGCM' (VERR_SSM_LOADED_TOO_MUCH).

Result Code: E_FAIL (0x80004005)
Component: Console
Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb}

Host is Windows 7 amd64, guest is Linux 3.1.

Have you tried discarding the saved state?

[Sam Morris]

No, as I wanted to keep it. I downgraded to 4.1.6 instead. :)

I have the same problem after update from 4.1.6 to 4.1.8. No snapshot will start. Same assert fails. Running 64bit linux as host and 32bit linux as guest. A newly created virtual machine works OK with snapshots, but none of the old ones will load.

Thanks for the report. We've fixed the issue, please try the following test builds:

• for ​Windows hosts
• for ​Linux amd64 hosts
• for ​Linux x86 hosts

and let me know whether it fixes the issue.

It would be great if you could try both to load saved states created with VBox 4.1.6 and with VBox 4.1.8 to ensure both of those work correctly.

Did anyone manage to test one of these builds?

[Frank Mehnert]

Fixed in VBox 4.1.10.
