Machine Build Error while adding support for http_server cpp

[b1shtream]

Refer https://github.com/unikraft/app-elfloader/pull/32

Reproduce an error:

Inside the app-elfloader directory, run the generate.py script ./scripts/generate.py.

Find scripts in the scripts/run/ directory named qemu-x86_64-9pfs-http_server.sh.

Build the elfloader by running ./scripts/build/make-qemu-x86_64-9pfs.sh

Then, running ./scripts/run/qemu-x86_64-9pfs-http_server.sh showed the error below-

[chococandy@fedora app-elfloader]$ ./scripts/run/qemu-x86_64-9pfs-http_server.sh

What could be the potential issue? It seems like something related to kvm. I am using Fedora Virtual Machine.
