Error running the Elf Loader

[lavanyamenon15]

We encountered a few errors when following the instructions to set up of the Elf Loader.

When we ran the following commands:

1. curl --proto '=https' --tlsv1.2 -sSf https://get.kraftkit.sh | sudo sh
2. git clone https://github.com/unikraft/app-elfloader elfloader
   cd elfloader/
3. kraft build (then choosing elfloader-qemu-x86_64-initrd-strace)
4. git clone https://github.com/unikraft/dynamic-apps
5. kraft run --target elfloader-qemu-x86_64-initrd-strace --plat qemu --initrd ../dynamic-apps/lang/c/helloworld/:/ -- /helloworld

We received a "path does not exist" error.

When we tried to fix this by running the following commands:

1. curl --proto '=https' --tlsv1.2 -sSf https://get.kraftkit.sh | sudo sh
2. git clone https://github.com/unikraft/app-elfloader elfloader
   cd elfloader/
3. kraft build (then chose elfloader-qemu-x86_64-initrd-strace)
4. git clone https://github.com/unikraft/dynamic-apps
5. kraft run (then chose elfloader-qemu-x86_64-initrd-strace)

We received "Init function at 0x16e7e0 returned error -1"

When we followed the "Quick Setup (aka TLDR)" everything worked except we had to use sudo in front of the last line below.

Sudo qemu-system-x86_64
