Guest OS time incorrect(not sync) after resume from "save the machine state"

[CharleXu]

Vbox/Ext. Ver: 4.3.6 r91406 Host: Mac OS X 10.9.1 Guest: Windows XP SP3

Suggest to make the guest additions sync with the host system time after resume.

Actually this is already implemented but of course only works if you have the VirtualBox Guest Additions installed (VBoxService must run in the guest). If that's the case for your guest, please attach the VBox.log file of your VM session.

I installed that additions and confirm that the service is running.

This issue also appears after the host sleep and wake with the power key or time out.

Host sleeping is another story. See the user manual section 9.14.3. A host sleep should be caught by the timesync threshold which defaults to 20 minutes. If the guest time differs more than 20 minutes from the host, the guest time is hard-set to the host time. And you can also see that timesync-set-on-restore is enabled by default so the question is why this doesn't work for you. Will do some local tests and come back later.

[CharleXu]

Yes, it often differs more than several hours.

Just tried to reproduce your problem with VBox 4.3.8 and failed. Please could you do the following: Open 'regedit' and change

HKLM\SYSTEM\CurrentControlSet\Services\VBoxService\ImagePath

to

system32\VBoxService.exe -vvvv --logfile c:\VBoxService.log

After that, reboot your guest. Then let it running for 1-2 minutes, then save the state, then wait for a few minutes, then restore the guest from the saved state. Now copy the file c:\VBoxService.log to somewhere out of your guest and attach the file to this ticket. This should help debugging your problem.

So, I just follow your comment, but no vboxservice.log there then I check that the vbox guest additional services is stopped as manual start. I thing it may be changed by my security/optimization software. All time sync correct after I started the services. Sorry for I just confirmed the services running by the sys tray icon and display driver looks ok before.

But I strongly suggest that icon in sys tray can identify the status of service running or stopped.

And please close this issue.

[Frank Mehnert]

That's a good idea. We will think about making the status of VBoxService visible in the VBoxTray icon. Thanks for the information.
