How to Debug Rust Program
Example
cloud-hypvisor vfio-device
Debug Cmd with rust-gdb
sudo rust-gdb --args ./cloud-hypervisor --kernel ./linux-cloud-hypervisor/arch/x86/boot/compressed/vmlinux.bin --console off --serial tty --disk path=clear-31890-kvm.img --cmdline "console=ttyS0 reboot=k panic=1 nomodules i8042.noaux i8042.nomux i8042.nopnp i8042.dumbkbd root=/dev/vda3" --cpus boot=4 --memory size=1024M --net "tap=,mac=,ip=,mask=" --rng --device path=/sys/bus/pci/devices/0000:05:00.0/,iommu=on,id=17
Tips: Command Start as rust-gdb --args ...
