Creating a boot disc for my current system (VM related)

Postby zoharl » Tue Dec 05, 2017 3:53 pm

I installed mint on a USB 3.0 pen drive. I'd like to use it inside a virtual machine (VMWare). It seems that those I tried (virtualbox, hyper-v), while supporting USB 3.0 (requiring kernel 3), they don't support booting from it. Currently, I reverted to using the slow USB 2.0, using plpbt (I can't find a similar app that supports USB 3.0).

An elegant solution that I'm considering is to boot my system from a disc image (.iso), but I'm not sure how to do that. It seems like the way to go is creating a customized live disc, but I was wondering if there's an easier way. I'd like to create an iso (which a VM has no problem booting), which would be minimal: It would contain the boot loader, kernel, and essentials to load my os and have a support for usb 3.0; from there it would continue running as usual from the pendrive.
Any suggestions?

If your virtual machine doesn't present physical USB3 ports as virtual USB3 ports, the guest software won't see USB3, even if it has drivers for it.

In 2016, when I last looked, syslinux and GRUB lacked internal USB3 drivers. GRUB would use the (virtual) BIOS to search for the kernel.

It does have usb3, but only after the system is loaded (needs kernel 3). Meaning, if, for example, I boot from a live cd and set the usb port to 3.0 (in the VM settings), then I am able to mount and use the stick as usb 3 (speed and all).
