The current implementation has the following bugs: - the vm variable is accessed after calling virDomainObjEndAPI on it - if VIR_STRDUP fails and we jump to the cleanup section, we're calling VIR_FREE on pointers for which we haven't allocated memory - the error type VIR_DOMAIN_DISK_ERROR_NONE is used which contradicts the documentation of the API that says that disks with no errors are not reported This patch fixes all of them and additionally reports errors only for every second disk (instead of reporting errors for all disks) which was the initial intention.
