VirtualBox 6.1.32 with extension 6.1.32 -time sync does not work

[OliverLi]

setting:
cd C:\Program Files\Oracle\VirtualBox
.\vboxmanage.exe guestproperty set "testlinux7" "/VirtualBox/GuestAdd/VBoxService/--timesync-interval" 10000
.\vboxmanage.exe guestproperty set "testlinux7" "/VirtualBox/GuestAdd/VBoxService/--timesync-min-adjust" 100
.\vboxmanage.exe guestproperty set "testlinux7" "/VirtualBox/GuestAdd/VBoxService/--timesync-set-on-restore" 1
.\vboxmanage.exe guestproperty set "testlinux7" "/VirtualBox/GuestAdd/VBoxService/--timesync-set-threshold" 1000

when I save state, and after 1 min start vm, no time sync happens.

any help appreciate.

I haven't played with time sync myself, but one thing I know for certain:

Ain't no way to Sunday that's the whole log.

Please tart the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

[OliverLi]

Thanks scottgus1.
The sync time is just for save-state and then start. if I reboot the vm , the vm time is same with host, but what I want is after save state and then start it.
Say I put my notebook sleep 2 hours, and then open it, the host time is right, but vm time is 2 hours behind.

I think the vm is designed to meet this requirement.
such as "--timesync-set-on-restore" , is said to set time after restore from save-state.

When it does not happen as it is supposed to, there is not much way to analyze it.

Thanks for you time and kind help.

Did you restart the VBoxService after setting the Guest Properties?

[OliverLi]

Did you restart the VBoxService after setting the Guest Properties?

Thanks reply.
I did that, nothing happened.
I checked the log , save-state, and then start.

I can't find any information of time sync. So maybe there is a switch for "time sync" ,and it just has n't been triggered?

[OliverLi]

I checked this post viewtopic.php?t=90233
and noticed I didn't install additional pack on client.
after I installed the pack on client (CentOS 7.9), I can find some sync information, but got error like

Apr 05 23:01:47 mysql06 kernel: 15:01:47.829394 timesync Error: vgsvcTimeSyncWorker: VbglR3GetHostTime failed; rc2=VERR_NOT_SUPPORTED

I attached the log file for reference.

Thanks.

Maybe I got the answer, my host is Windows 11, it's not on the support list.

Well, everything works just like you've configured it: You've forbidden VirtualBox to synchronize the guest time with the host time, and then configured the time synchronization to take place at certain times. Works perfectly.

Seriously, see 9.11.4. Disabling the Guest Additions Time Synchronization. Use the documented command without the trailing "1" to remove this setting.

Thank you very much.
Finially it's fixed.

Just a weird thing, I changed the parameters wth the vboxmanage.exe guestproperty set command,
and I checked the .vbox file, it has been changed.

BUT when I start the virtual machine, the .vbox file was replaced with a wrong one, the one before I change .

I unregistered the virtual machine, edit the .vbox file manually, and then register it. Then it used the right .vbox file, and everything is OK.

After I reboot my notebook (windows 11), the weird thing disappeared.

SO, after started the virtual machine, make sure to check the .vbox file, if it is still the right one. That's very important. maybe reboot the notebook is a must thing.
Thanks again.
