Serial output was silent (x-option-roms=off suppresses BIOS serial init); fixed by removing it from the machine string and using -serial chardev:console0 to attach to the machine-created ISA serial device instead of adding a duplicate isa-serial device (which would create ttyS1 while kernel uses ttyS0). virtio-net interfaces were invisible to the kernel because QEMU's auto-kernel-cmdline does not append virtio_mmio.device= params when -append is used. Fixed by generating explicit virtio_mmio.device=0x200@0xfebNNNNN:N params for each NIC in KernelCmdline, and modprobing virtio_mmio + virtio_net in init.sh. sys.micro bumped to 512 MiB — 128 MiB caused kernel OOM during initramfs decompression (~68 MiB uncompressed). BusyBox init ::respawn: entries do not source or export env files; fixed inittab to use set -a; . /etc/conf.d/lb-agent; set +a before exec. wireLBAgentConfig was documented as reading the CA cert but never set elbv2Service.CACert; lb-agent TLS handshakes to AWSGW failed with x509: certificate signed by unknown authority. Fixed by reading d.config.NATS.CACert (same local CA that signs the AWSGW server cert) and assigning to elbv2Service.CACert so writeFwCfgBlobs writes a non-empty cacert blob into fw_cfg. Adds vm_test TestExecute_MicrovmFileChardev and updates lifecycle_test to assert SerialSocket is intentionally empty on direct-boot VMs.
