I'm having a similar issue, running on an EC2 instance with Ubuntu 18.04 as host, though I'm not sure I'm doing anything correctly with netplan (still trying to figure out what the conversion should be). Is it recommended that we revert back to ifupdown?
Same here. I'm no expert in networking, however, something that I've noticed is that inside the machine, while netstat
displays dropbear listening on 0.0.0.0:22
, trying to connect to that port (telnet localhost 22
) fails.
Follow this tutorial on Ubuntu 18.04. https://risc-v-getting-started-guide.readthedocs.io/en/latest/linux-qemu.html
It generates a busybear.bin which is bootable. Everything seems ok except the network.
In QEMU guest: root@busybear:~# ifconfig eth0 Link encap:Ethernet HWaddr 52:54:00:12:34:56

The network seems to be configured correctly. But guest doesn't have internet connection. Also, I Cann't ssh into the guest from my host machine.
I am using the following start command: sudo qemu-system-riscv64 \ -nographic \ -machine virt \ -kernel riscv-pk/build/bbl \ -append "root=/dev/vda ro console=ttyS0" \ -drive file=busybear-linux/busybear.bin,format=raw,id=hd0 \ -device virtio-blk-device,drive=hd0 \ -device virtio-net-device,netdev=usernet \ -netdev user,id=usernet,hostfwd=tcp::22222-:22
Any suggestion?
