The virtual machine starts and freezes

Hi

I installed Virtualbox 6.1 (instead of Virtualbox 5.1) on a VPS hosted by Scaleway.

As soon as I start the machine:
VBoxManage startvm "xp pro sp3 24 04 14" --type headless
The screen appears on Remote Distance (on Windows 7), sometimes there is the loading of Windows XP but then the screen freezes, it does not want to continue.

Do you know where the problem could come from?
Because on Virtualbox 5.1 everything worked.

I have Debian 10 and Virtualbox 6.1

cordially

This appears to be nested virtualization.

If the VPS environment did not pass 'virtualization technology' (VT-x/AMD-V/SVM, abbreviated "VT" in this post) into the VM environment, then Virtualbox up to 6.0.x allowed running without "VT", 1-core 32-bit guests, Windows 8 and earlier. Windows 8.1 and later could not run even in 1-core 32-bit without "VT". Probably some similar limitation in Linux OS's.

From Virtualbox 6.1.x onward, "VT" is required in the OS for all guests.

It appears that your VPS is not passing "VT" into its VM, so you will be limited to Virtualbox 6.0.x at most, unless you can get them to pass "VT".
