Remove the QEMU_USE_MICROVM env-gated microvm machine type path. Always use q35 (x86_64) or virt (aarch64) with unnecessary subsystems disabled. Strip redundant QEMU flags already implied by -nodefaults, suppress PXE ROM loading on virtio-net, add kernel parameters to skip unneeded init work, and reduce SSH readiness polling from 500ms to 100ms. This allows for faster boot times. Signed-off-by: Luca Di Maio <[email protected]>
