… queries during migration Three methods called _networksDao.findById(nic.getNetworkId()) per NIC in a loop: setHypervisorHostname, prepareNicForMigration, prepareAllNicsForMigration. Now batch-loads all networks for a VM's NICs in a single WHERE id IN (...) query. - Add NetworkDao.listByIds(List<Long>) for batch ID lookup - Add getNetworkMapForNics helper returning Map<Long, NetworkVO> - Replace per-NIC findById with map lookup at 3 sites - Add null guard for deleted networks (pre-existing NPE risk on all 3 sites) - Site 2 (prepare) left unchanged — findById only on error path, not N+1

@vishesh92 a [SL] Jenkins job has been kicked to build packages. It will be bundled with no SystemVM templates. I'll keep you posted as I make progress. |

Description
Three methods called _networksDao.findById(nic.getNetworkId()) per NIC in a loop: setHypervisorHostname, prepareNicForMigration, prepareAllNicsForMigration. Now batch-loads all networks for a VM's NICs in a single WHERE id IN (...) query.
