I have a live-Snapshot created some time in 2019. I already had GetHostTimeDisabled set to 1 when I created the snapshot and currently,
Code: Select all
VBoxManage.exe getextradata "Win 7 SW Comp" VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled
The guest has a network adapter, but its set to "not connected".
I need to shut down the guest to increase the RAM, VRAM and processor core settings. But every time I do, the time is updated, which is not what I want.
Updating VirtualBox is also not really possible, because the live snapshots will stop working.
Here is what I tried already:
Attempt 1:
- Start live snapshot from manager
- Reboot from start menu
- Time stays at 2019
- Reboot from msconfig changef
- Time stays at 2019
- Shutdown from start menu
- Boot from manager
- Time is updated
- Start live snapshot from manager
- Close VM window without returning to snapshot
- Boot from manager
- Time is updated
- Discard live-data in manager
- Boot from manager
- Time is updated
- Start live snapshot from manager
- Uninstall guest additions
- Reboot from setup
- Time stays at 2019
- Reboot from start menu
- Time stays at 2019
- Shutdown from start menu
- Boot from manager
- Time is updated
- Start live snapshot from manager
- Uninstall guest additions
- Reboot from setup
- Time stays at 2019
- Close VM window without returning to snapshot
- Boot from manager
- Time is updated
- Start live snapshot from manager
- Reboot from setup
- When VirtualBox BIOS logo is visible, close VM window without returning to snapshot
- Boot from manager
- Time is updated
- Start live snapshot from manager
- Uninstall guest additions
- Reboot from setup
- When VirtualBox BIOS logo is visible, close VM window without returning to snapshot
- Boot from manager
- Time is updated
Code: Select all
VBoxManage.exe setextradata "Win 7 SW Comp" VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled 1
How do I shut down and then boot the guest without its time being updated?
A workaround is this:
- Set host time to 2019
- Start live snapshot from manager
- Shutdown from start menu
- Change RAM, VRAM and cores
- Boot from manager
- Time is still updated, but to 2019
