I did have a little bit of a look at this. It seems to hang during key generation before starting the server during boot. I had a suspicion that the problem could be a lack of entropy. We're supposed to have the virtio entropy generation being passed through from the host to avoid problems with entropy starvation but I'm not sure its running for arm64. I noticed the .config shows CONFIG_CRYPTO_DEV_VIRTIO=m but setting that to =y didn't help. The virtio rng connects via pci bus iirc and CONFIG_PCI isn't set so I'm now looking into that... To update, adding this config to the kernel: CONFIG_CRYPTO_DEV_VIRTIO=y CONFIG_PCI=y CONFIG_PCI_HOST_GENERIC=y appears to solve the problem and lets my simple tests work. I'll have to run some better tests but I think this is the problem, lack pci support in the kernel meaning the rng virtio passthrough doesn't work.
