Hi, during setup of cloudstack, table `hypervisor_capabilities` is created by https://github.com/apache/cloudstack/blob/3a326f7280fefcd809573149ceb05b5fc7d07893/setup/db/create-schema.sql#L1657 with "default" entry for `KVM` https://github.com/apache/cloudstack/blob/3a326f7280fefcd809573149ceb05b5fc7d07893/setup/db/create-schema.sql#L1681 which results in `max_data_volumes_limit` for "kvm default" is set to 6 by https://github.com/apache/cloudstack/blob/3a326f7280fefcd809573149ceb05b5fc7d07893/setup/db/create-schema.sql#L1664 --- Now in case of creating an instance in state `stopped` it is never started and therefor `vm.getLastHostId()` returns NULL in https://github.com/apache/cloudstack/blob/3a326f7280fefcd809573149ceb05b5fc7d07893/server/src/main/java/com/cloud/storage/VolumeApiServiceImpl.java#L3252 and "fallback if no proper configuration is found" is triggered, which grabs the `max_data_volumes_limit` value for "default" hypervisor version (_which was set to 6 during setup_) https://github.com/apache/cloudstack/blob/3a326f7280fefcd809573149ceb05b5fc7d07893/server/src/main/java/com/cloud/storage/VolumeApiServiceImpl.java#L3266 --- But once the instance is deployed, `vm.getLastHostId()` will return a valid hostId, which results in respecting the real hypervisor version at https://github.com/apache/cloudstack/blob/3a326f7280fefcd809573149ceb05b5fc7d07893/server/src/main/java/com/cloud/storage/VolumeApiServiceImpl.java#L3262 --- I hope this will help to figure out, what happens, if it is a bug or a feature and how to proceed with this case. regards, Michael ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
