Any return of NULL without a last error set is a bug. I'm trying to
chase this down, and hope to have a patch soon.
I can't reproduce this. I tested on libvirt 0.9.10, starting with an
inactive domain 'dom' and using 'virsh dumpxml dom > dom.xml; virsh
create dom.xml; virsh create dom.xml', and the second create gave me a
proper error message of "Requested operation is not valid: domain is
already active as 'dom'".
Can you post the code snippet you are using to get this situation?
Could it be that you have a different name and/or UUID in the xml from
the domain already running (my test obviously reused the same name and
uuid from what is already running).
