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. </pre> </blockquote> It looks to me all of the dirvers which supports domain undefine don't allow to undefine a running domain, except xend, ESX, and xenapi, which leave the determination to the underlying hypervisor. <blockquote cite="mid:4E1F1887.20104@redhat.com" type="cite"> <pre wrap="">Either Dan, do you want to weigh in on this API question? </pre> </blockquote> <blockquote cite="mid:4E1F1887.20104@redhat.com" type="cite"> <pre wrap=""></pre> <pre wrap=""> <fieldset class="mimeAttachmentHeader"></fieldset> -- libvir-list mailing list <a class="moz-txt-link-abbreviated" href="mailto:libvir-list@redhat.com">libvir-list@redhat.com</a> <a class="moz-txt-link-freetext" href="https://www.redhat.com/mailman/listinfo/libvir-list">https://www.redhat.com/mailman/listinfo/libvir-list</a></pre> </blockquote> </body> </html>
