Hello,
I’m facing some strange behavior, and I hope you can provide a
clarification.
Consider the following code:
virDomainPtr dom = virDomainLookupByName(virt, domain_name);
if (dom) {
printf("domain already defined...\n");
if (virDomainUndefine(dom))
printf("...unable to undefine!!!\n");
else {
printf("...undefined.");
free(dom);
}
}
You're leaking a virDomainPtr here. Call virDomainFree(dom) before
overwriting the pointer with the result from virDomainDefineXML.
I think the leaked virDomainPtr causes the trouble you describe. So
fixing the leak will probably also fix the problem you see in the
second run.
dom = virDomainDefineXML(virt, SOME_XML);
