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");
}
