Hi. I'm working on a new camkes-based project. This project is simulated by using Qemu, on a Q35 machine for X86_64 arch and e1000e eth. I am using an intel controller driver (82574 controller) for network communication. My project has been built successfully and the intel network driver has been initialized.
But when using the network in my application in Qemu, no network packet is sent and received!
Qemu command:
``` sudo qemu-system-x86_64 -machine q35,accel=kvm,kernel-irqchip=split -cpu host, -netdev tap,id=netdev0,ifname=tap0,script=no,downscript=no -device e1000e,id=nic0,netdev=netdev0,mac=52:55:00:d1:55:01 -nographic -serial mon:stdio -m size=4G -device intel-iommu -kernel ./target/debug/images/kernel-x86_64-pc99 -initrd ./target/debug/images/capdl-loader-image-x86_64-pc99 ```
.
Appendix: Create tap0 command: ``` export TAP_DEV=tap0 sudo ip tuntap add dev $TAP_DEV mode tap sudo ip addr flush dev $TAP_DEV sudo ip addr add 10.10.100.1/24 brd 10.10.100.255 dev $TAP_DEV sudo ip link set dev $TAP_DEV addr 02:00:ca:fe:01 sudo ip link set dev $TAP_DEV up ```
.
how to fix this problem? Thank you.
