Run VM with qemu with your TPM

example of how to use it

./run_vm_with_drive disk1.qcow2 /dev/sda NUMBER_CPU_YOU_WANT /dev/tpm0

Arguments:

• disk1.qcow2 if the disk doesn't exist will create a new disk
• /dev/sda your pendrive or any other aditional media to use as installation media
• NUMBER_CPU_YOU_WANT (OPTIONAL) set the number of core you want the VM to have (default: 1)
• /dev/tpm0 (OPTIONAL) set the tpm device used by the VM (default: /dev/tpm0)
