nova 无法迁移的问题

由于之前调整了一波可用域以及主机组，旧的机器便不能迁移了

问题与log

/var/log/kolla/nova/nova-scheduler.log:2021-04-27 14:04:16.662 64 DEBUG nova.scheduler.filters.availability_zone_filter [req-9377a72c-7d0a-4efa-8f29-5c7c961c7ae8 185f782e50331bdee5890a3a5a09617246846b9e9bc56c1ac44d0686ba92666d 7ff7b55097ef43358a7a3e6cac34fb2f - 91b8c1549b614a038dcd8395ece8de60 91b8c1549b614a038dcd8395ece8de60]

    if 'availability_zone' in metadata:
        hosts_passes = availability_zone in metadata['availability_zone']
        host_az = metadata['availability_zone']
    else:
        hosts_passes = availability_zone == CONF.default_availability_zone
        host_az = CONF.default_availability_zone

    if not hosts_passes:
        LOG.debug("Availability Zone '%(az)s' requested. "
                  "%(host_state)s has AZs: %(host_az)s",
                  {'host_state': host_state,
                   'az': availability_zone,
                   'host_az': host_az})

目前怀疑是旧的这批机器当时指定的可用域不存在了，和当前的可用的一批可用域也匹配不上

解决：

更改之前的可用域 到现在的可用域即可
