Hello!

If one were to make changes to both Firecracker and OSv (e.g., in the 
para-virt interfaces) what options are there for debugging guest kernel 
state? I understand booting OSv alternatively on KVM/QEMU would make 
inspection possible, but doing so requires changes I wish to test to be 
implemented in QEMU.

Folks working on Firecracker tell me it does not have a gdbserver 
implementation like QEMU does, thus this path is not possible, currently.

How do you / would one go about debugging OSv behavior as a guest within 
Firecracker?

Thanks,
Alex Merritt
