"Your network is probably not using DHCP protocol" during ubuntu install on qemu virtual machine

[ckim]

Hello, all

I’m install ubuntu 20.04 on an arm64 virtual machine using qemu-5.1.0. (host is also ubuntu 20.04, am64 machine)

The final command is below. (the LD_LIBRARY_PATH setting was needed for sudo)

sudo LD_LIBRARY_PATH=/home/ckim/prj/abdsn/ab21sim/axpusim/build ./qemu-system-aarch64 -nographic -machine ab21q,gic-version=max -m 512M -cpu max -smp 4 \

-netdev user,id=vnet,hostfwd=:127.0.0.1:0-:22 -device virtio-net-pci,netdev=vnet \

-drive file=ab21q-ubuntu-20.04-image.img,if=none,id=drive0,cache=writeback -device virtio-blk,drive=drive0,bootindex=0 \

-drive file=ubuntu-20.04-mini.iso,if=none,id=drive1,cache=writeback -device virtio-blk,drive=drive1,bootindex=1 \

-drive file=flash0.img,format=raw,if=pflash -drive file=flash1.img,format=raw,if=pflash --enable-kvm

 

I’ve done this before (on intel ubuntu 20.04 machine) with no problem, but this time, I get this message. (I’m not sure I had this before too).

“Your network is probably not using DHCP protocol. Alternatively, the DHCP server may be slow or some network hardware is not working properly.”

 

My host’s network is working properly. What can I do?

I’m doing this remote from home and I can set my host to use DHCP and to use DHCP-given IP address tomorrow if needed. Should I do this? Or should I install DHCP server on the host?

Thank you!
