Opps, I made a mistake only checking the hypervisor, which of course
will not know about the domain if it is shutoff :-) Adding the following
extra hunk fixes it
@@ -664,11 +664,21 @@ xenUnifiedDomainIsActive(virDomainPtr dom)
int ret = -1;
/* ID field in dom may be outdated, so re-lookup */
- currdom = xenHypervisorLookupDomainByUUID(dom->conn, dom->uuid);
+ currdom = xenHypervisorLookupDomainByUUID(conn, uuid);
+
+ /* Try XM for inactive domains. */
+ if (!currdom) {
+ if (priv->xendConfigVersion <= XEND_CONFIG_VERSION_3_0_3)
+ currdom = xenXMDomainLookupByUUID(conn, uuid);
+ else
+ currdom = xenDaemonLookupByUUID(conn, uuid);
+ }
if (currdom) {
ret = currdom->id == -1 ? 0 : 1;
virDomainFree(currdom);
+ } else if (virGetLastError() == NULL) {
+ virReportError(VIR_ERR_NO_DOMAIN, __FUNCTION__);
}
return ret;
