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);
}
}
dom = virDomainDefineXML(virt, SOME_XML);
if (dom != NULL) {
const char *name = virDomainGetName(dom);
printf("NAME IS NOW: %s\n", name);
} else
printf("dom is NULL!\n");
When executed the first time, the code correctly defines the domain, and
prints:
defining domain test2-vm
libvir: QEMU error : Domain not found: no domain with matching name
'test2-vm'
NAME IS NOW: test2-vm
If executed a second time with the same SOME_XML when the domain is
already defined, it prints:
defining domain test2-vm
domain already defined...
libvir: Domain error : invalid domain pointer in virDomainGetName
undefining......undefined.NAME IS NOW: (null)
Not only the name is null, but the domain can't be started. What is the
correct way to undefined programmatically a domain that is already
defined? Why is the second virDomainDefineXML() returining a pointer (as
opposed to null), but the pointed object seem to be invalid?
Thanks,
Roberto
