When attempting to hotplug a virtio-serial console to a domain
that had no virtio-serial controllers (not even those that
are added by libvirt when some devices need them) at daemon startup,
report a user-friendly error:
error: Failed to attach device from console.xml
error: internal error: no virtio-serial controllers are available
instead of crashing the daemon:
Process terminating with default action of signal 11 (SIGSEGV): dumping core
Access not within mapped region at address 0x8
