Guest’s Clock Problems

[SwetikTswetik]

Hello!
I need my guest to flash-back a long long time ago, so approximately back to 2006. But problem is that my guest is just damned stubbornly synchronize itself with my host!!!
Also sure in this case it would be good to slow down guest’s time to its net working time at the same time.


It appears as if this point of built-in help content would be the solving:
“9.15. Configuring the guest time stamp counter (TSC) to reflect guest execution”
but it unfortunately does not want work. Due to the note:
“This special TSC handling mode can be enabled on a per-VM basis, and for best results must be used only in combination with hardware virtualization”
both these options have I enabled:
Enable VT-x/AMD-V
Enable Nested Paging
but still no anticipated results.




Windows Guest Additions on guest – installed.

What could I do wrong else? Maybe wrong entry in the “Command Prompt”?
I first time deal with “Command Prompt”, thus I might not understand using “VBoxManage setextradata "My VM" "VBoxInternal/TM/TSCTiedToExecution" 1” command process grosso mode.
Path in the “Command Prompt” must not be with printing errors, but I used automated means by “Total Commander” & “Paste” command.
Here the snapshot.

What if you set the host time back.

.

Then Guest sets its time after Host and sticks to it strictly.
That is directly the problem i told about right above!

Happy New Year to ALL

Try:

Code: Select all

VBoxManage setextradata "My VM" "VBoxInternal/TM/UTCOffset" -126144000000000000

... this should set the VM clock to be in sync with the host clock, BUT 4 years in the past (4*365*24*60*60*10^9 ns).

Edit: This can also be set using:

Code: Select all

VBoxManage modifyvm "My VM" --biossystemtimeoffset <msec>

... this should set the VM clock to be in sync with the host clock, but <msec> (milliseconds) offset. Negative numbers put the VM clock in the past, positive numbers put the VM into the future.
