Undefine the configuration for an inactive domain. Since it's not running the domain name or UUID must be used as the I<domain-id>. Oh, this is different than libvirt.c, which claimed you can run 'undefine' on a running persistent domain. Which is it? Can undefine make a running domain transient, or must it be on an inactive domain?
No, document in libvirt.c is not correct, undefining on a running domain will be refused.
I argue that we found a bug in the qemu driver then.
Right now, you can use 'virDomainDefineXML' to convert a transient guest into a persistent one, but there is no counterpart operation to convert a persistent guest back into a transient one.
That is, I think the libvirt.c docs are right in implying that you can 'undefine' a running domain, and that the qemu driver needs to be fixed to allow this use case.
Either Dan, do you want to weigh in on this API question?
I also side on the side that it should be allowed and it's "just" a qemu driver bug :-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
