Re: [libvirt-users] Fwd: undefining and redefining a Domain from libvirt java bindings

You need to free() all domain objects that represent the undefine domain before defining a domain with the same name again: System.out.println("first define tt2..."); Domain dm1 = conn.domainDefineXML(dumpxml); Domain dm2 = conn.domainLookupByName("tt2"); System.out.println("Now undefine...."); if (dm2 != null) { System.out.println("undefine tt2..."); dm2.undefine(); dm2.free(); dm1.free(); // <---------- need to free dm1 here too System.out.println("undefine tt2... done"); } Matthias 2010/10/21 Ravi Pawar <ravifc(a)gmail.com&gt;: > Thanks Matthias, > > can you please have a look at the program attached? this should work as i > have used free() call. but its not working for me. > > Thanks, > Ravi > > On Mon, Oct 18, 2010 at 6:20 PM, Bryan Kearney <bkearney(a)redhat.com&gt; wrote: >> >> On 10/15/2010 10:05 AM, Matthias Bolte wrote: >>> >>> 2010/10/13 Matthias Bolte&lt;matthias.bolte(a)googlemail.com&gt;: >>>> >>>> 2010/10/12 Matthias Bolte&lt;matthias.bolte(a)googlemail.com&gt;: >>>>> >>>>> 2010/10/12 Ravi Pawar&lt;ravifc(a)gmail.com&gt;: >>>>>> >>>>>> hi, >>>>>> >>>>>> i am trying to undefine a domain by using dm.undefine(); >>>>>> and then trying to create one with same name is giving me error saying >>>>>> 'Domain not found: no domain with matching uuid >>>>>> 'aeae9d4e-17cb-b661-a612-88ac677c28c1' >>>>>> >>>>>> i have attached my test program which reproduces the issue. >>>>>> >>>>>> please let me know where i am going wrong? >>>>>> >>>>>> configuration: libvirt : 0.6.3 >>>>>> Java Bindings: 0.4.2 >>>>> >>>>> I didn't look into this problem in detail, but I think you need to >>>>> call free on the Domain object after you undefined it. >>>>> >>>>> dm.undefine(); >>>>> dm.free(); >>>>> dm = null; >>>>> >>>>> Matthias >>>>> >>>> >>>> Okay, calling free doesn't help.
