Quickly testing live usb using qemu-system

You will need qemu for this. Install qemu-system for x86 machine (intel based)

$ sudo apt install qemu-system-x86

Attach your usb, check the device name using lsblk

$ lsblk

Test run your live usb using qemu-system-x86_64 command. Let's say your usb device is /dev/sdb

$ sudo qemu-system-x86_64 -hda /dev/sdb

If you get kernel panic in qemu when you run the above command, assign higher memory to the command, because qemu by default only assign 128MiB

$ sudo qemu-system-x86_64 -m 512 -hda /dev/sdb
