From: Zhou Yimin <zhouyimin(a)huawei.com&gt; If hypervisor is not Xen, the errs in struct _virDomainBlockStats will be -1. But in KVM when we call domain.blockStats(), errs is 18446744073709551615. To fix that, this patch has two changes: 1. Replace use of the PyLong_FromUnsignedLongLong with PyLong_FromLongLong in function libvirt_longlongWrap 2. If the paramemter of libvirt_longlongWrap is unsigned long long, use libvirt_ulonglongWrap instead because of above change. After this patch, errs is -1 which is consistent with virDomainBlockStats api.
