Virtual machine - booting from USB?

[Hans <hans.ullrich@loop.de>]

Hi folks,

does one know, if it is possible to boot from an USB-stick within a virtual 
machine?

I want to boot a multiboot usb stick with YUMI within a virtual machine.

Tried Virtualbox (here you can only make a *.vdk from the USB-stick and boot 
it), as well as virtual-manager (seem also only be capable to boot images) and 
quemu (with aqemu gui). Last also images, no devices.

However, I don't now if this is possible at all, so I allowed me to as here, 
if one knows, if this is possible with some virtual machine - just before I am 
trying and searching until my death.

Hint
YES - I could create an ISO-image from the USB stick and copy this to another 
USB-stick, then mount it and thenn boot it. This will work!

But NO, I do NOT want to create an ISO from the USB-stick, I just want to 
leave it as it is for some reasons.

Short answer like "yes, it wqill wor with...."  or "no, this is not 
possible..." will be fine for me.

Thanks for reading.

Best regards

Hans
