# This script is used to generate QEMU arguments for OSDK.
# The positional argument $1 is the scheme.
# A switch "-ovmf" can be passed as an argument to enable OVMF.
# The enrivonmental variable VSOCK can be passed as 1 to trigger vsock module.
# Usage: `qemu_args.sh [scheme]`
# - scheme: "normal", "microvm" or "iommu";
# Other arguments are configured via environmental variables:
# - OVMF: "on" or "off";
# - NETDEV: "user" or "tap";
# - VHOST: "off" or "on";
# - VSOCK: "off" or "on";
# - SMP: number of CPUs;
# - MEM: amount of memory, e.g. "8G".
