[RFE] autodetect/parametrize vtoyboot to skip if virtual-machine boot about vtoyboot

[ventoy]

vtoyboot does detect the boot environment when booting.
If currently is not booted from Ventoy then it will not create dm device and will continue the normal boot.

1. Create a new disk image and boot from QEMU
2. Install a distro to the VM (e.g. Ubuntu)
3. After install, run vtoyboot in the system.
4. reboot the VM

Can step 4 boot normal to the VM? (I test with VirtualBox and this is OK)

okay, its my bad. Sorry for false alarm and thank you for replying. There have been package-updates in the intervening time and so bug may have been spurious.

I attempted a couple of VM boots, post-install of vtoyboot and image booted successfully to GUI.
Image installed was a fresh fedora 36 beta

Its good to know that it will also work on virtualbox.

I should have been more perceptive and looked more closely to see how far into the boot process that spurious attempt had gone, and for what reason it stalled. I will do so next time if it ever reoccurs.

I will close this bug for now, and reopen only if I can recreate it.
