Very nice! I tried a couple of things, including interactive applications
which didn't work correctly yesterday, but now seems to work correctly.
Great work!

A few final points on my wishlist for this subject (none of this is urgent):
1. Avoid the conversion to the (very large...) "raw image" in
scripts/firecracker.py. According to an example
https://medium.com/@s8sg/quick-start-with-firecracker-and-firectl-
2. Find the places in the documentation (?) where we list the supported
hypervisors, and add Firecracker to the list.
in-ubuntu-f58aeedae04b, it seems firecracker is supposed to support qcow2,
not just raw images?
3. scripts/run.py has a "-p" option to choose hypervisor (see "launchers =
..." list in run.py), we could add firecracker to this list and call
scripts/firecracker.py.
4. Now that you fixed the vmlinuz support, does it mean we can also use
Qemu's "-kernel" option? Does it make boot any faster?
