Btw, I just cut EVE release 5.12.3-rpi-xen-arm64 (there's also 5.12.3-rpi-kvm-arm64 of course -- but this is Xen thread ;-))) that fixes a few issues that were reported ever since we got slashdotted this morning. This is your best bet in trying Xen/EVE/RPi4 combo. E.g. docker run lfedge/eve:5.12.3-rpi-xen-arm64 live > live.raw is literally all you need to get going.
