Please enable CONFIG_MACVTAP kernel option #4413

Open jbrnd opened 3 years ago

jbrnd commented 3 years ago

Please enable the MACVTAP kernel option (CONFIG_MACVTAP=m). This option is necessary for having bridge-like networking on KVM VMs with the host root filesystem on NFS (since regular bridge networking doesn't work in that case),

I have recompiled the kernel on my Raspberry Pi 4 (see version information below), and everything works fine with the MACVTAP option enabled.

This options adds two modules totalling ~50kB, and only on arm64, so it's an easy yes.
