hello,
last night our ops live migrated (nova live-migration --block-migrate
$vm) a group of vm to do hw maintenance. some of the vm ended on a
different AZ making the vm unusable (we have different upstream network
connectivity on each AZ)
I haven't read all the logs yet, but i remember when i created the zones
i did test live migrations and it always remain in the same AZ.
I googled and nothing appears, i wonder if somebody else had this
problem or is not even supposed to work and i got lucky until today?
of course, i have setup AZ filter
scheduler_available_filters=nova.scheduler.filters.all_filters
scheduler_default_filters=RetryFilter,AggregateInstanceExtraSpecsFilter,AvailabilityZoneFilter,RamFilter,CoreFilter,DiskFilter,ComputeFilter,ImagePropertiesFilter
