A thorn in my side for the last few months...
I set up some shiny new virtual machines mostly for #ReproducibleBuilds on a #HoneyCombLX2 packed with 64GB of ram and 16 cores of modest ARM compute power...
only to be stumped on the networking.
The virtual machines were set up to use macvtap via virt-manager in the same way as several other machines... no network.
Today I tried using a USB ethernet adatper. Worked like a charm!
What could cause #macvtap to not work with the onboard #ethernet ?
Installed a cheap PCIe gigabit ethernet card, and that worked fine!
So something with the onboard #ethernet on the #HoneyCombLX2 hardware or driver is broken for #macvtap
At least PCIe works well enough, surely better than #USB dongles!
@vagrantc promiscuous mode?
@vagrantc Perhaps the driver for the onboard Ethernet claims to support multiple unicast filters but it's broken
