If qemu is run like: qemu-system-ppc64 -nodefaults -device spapr-vty We end up in spapr_vty_init() with dev->chardev == NULL. Currently that leads to a segfault because we unconditionally call qemu_chr_add_handlers(). Although we could make that call conditional, I think a spapr-vty without a chardev is basically useless so fail the init. This is similar to what the serial code does for example.
