Exactly the same guest(Win7) on 2 different hosts but no luck

[Alex.F]

I am using the same VirtualBox with the same extension on 2 different hosts, trying to launch totally the same guest(Win7).

But, the result goes into 2 different ways.

I tried to figure out the log file but.....

Please help me~~~

I see no error in the log. All I see is the VM window being closed by user action after only 1 min 20 secs. Also the VM only has 1 core and is being launched from an external drive - hopefully not a USB flash drive?

@mpack
Thanks for you reply.
User shutting down the VM through GUI is because guest(Win7) was just hanging there with windows logo dimming-lighting back and forth. The same phenomenon happens while I create whole new guest trying to install OS start over. Log file is attached.

Yes, VM guest is on USB flash drive. But, I used to use this guest on USB drive before, and it works well. ( on my RMA Surface Pro)

I've also noticed that my VT-x service isn't enabled, trying to fix it.

No, it's just hidden by Hyper-v.
