KVM
|
This image is compatible with the Raspberry Pi 3 too, but only ARMv7 is supported now.
|
||||||
===
|
|
||||||
|
|
||||||
This build requires a host capable of KVM. If you don't have KVM then remove `ENV DAPPER_RUN_ARGS --device /dev/kvm` from `Dockerfile.dapper`, but it will run very slow.
|
Build Requirements
|
||||||
|
==================
|
||||||
|
|
||||||
|
This build uses local loopback devices and thus requires to run as a privileged container. So please keep the setting `ENV DAPPER_RUN_ARGS --privileged` from `Dockerfile.dapper` for now. The build is running quite fast and has been tested on OS X with boot2docker.
