Currently, there's a bug when undefining a domain with NVRAM
store. Basically, the unlink() of the NVRAM store file happens
during the undefine procedure iff domain is inactive. So, if
domain is running and undefine is called the file is left behind.
It won't be removed in the domain cleanup process either
(qemuProcessStop). To avoid this forbid undefining domain with
NVRAM file.

Why do we need to forbid it ? Even if QEMU still has an open
file handle, it can continue to write to it after we unlink
it.


It was a suggestion, because that's what will people expect, IMHO.

Feel free to go with the first version if that's what Dan prefers.


Regards,
Daniel
