If a domain has PCI devices then we can't safely save or migrate it. At least one user has had system crashes due to this, and the way the xendomains script automatically saves and restores domains on reboot. Since there's no sensible semantics for it at the moment, we should disallow it and return an appropriate error message to xm. The first attached patch prevents the suspend from occurring, the second ensures that the appropriate errors are fed back to the user.

Mark: To answer a question with a question: What use is a skateboard? Dave: Skateboards have wheels. Mark: My wheel has a wheel! Attachment:
