unable to locate qemu0 - net bridge qemu0: bridge helper failed #2

Closed puccaso closed 2 years ago

puccaso commented 2 years ago

Hello,

trying to run this on a raspberry pi 4, the container builds fine, I eventually got the data on the device, but looks like qemu0 can't be found.

i played around a bit hoping that if qemu0 was missing, maybe br0 may be there, but that wasn't there either. virbr0 maybe? next: testing bridged networking via a docker-compose setting...

any help would be great.

Hello,

qemu0 is a bridge that must be created on the host OS by the user, it doesn't exist by default in balenaOS. Refer to the documentation here: https://github.com/balena-io-playground/balenaVirt#shared-physical-device
