[libvirt] [PATCH] openvz: Handle domain obj hash map errors

This makes the driver fail with a clear error message in case of uuid collisions (for example if somebody copied a container configuration without updating the UUID). OpenVZ itself doesn't complain about duplicate UUIDs since this parameter is only used by libvirt. --- src/openvz/openvz_conf.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/src/openvz/openvz_conf.c b/src/openvz/openvz_conf.c index 503c8a0..0764c2c 100644 --- a/src/openvz/openvz_conf.c +++ b/src/openvz/openvz_conf.c @@ -684,8 +684,11 @@ int openvzLoadDomains(struct openvz_driver *driver) { openvzReadMemConf(dom->def, veid); virUUIDFormat(dom->def->uuid, uuidstr); - if (virHashAddEntry(driver->domains.objs, uuidstr, dom) < 0) + if (virHashAddEntry(driver->domains.objs, uuidstr, dom) < 0) { + openvzError(VIR_ERR_INTERNAL_ERROR, + _("Could not add UUID for container %d"), veid); goto cleanup; + } virDomainObjUnlock(dom); dom = NULL; -- 1.7.10.4
