Because the VM was never created, the test then attempts to delete a VM that doesn't exist, causing test_03_delete_vm to fail.\n\nThe test does not currently handle this resource-limit API error as a valid/expected outcome.\n\n### versions\n\nApache CloudStack version: main branch (4.23.0.0-SNAPSHOT)\nEnvironment: GitHub Actions Simulator CI (advanced zone), simulator hypervisor — not a real deployment\n\n### The steps to reproduce the bug\n\n1. Run the Simulator CI test suite including component/test_mm_domain_limits.py\n2. Observe test_03_delete_vm\n3. deployVirtualMachine fails with errorCode 535 (memory limit exceeded)\n4. Test then attempts to delete a VM that was never created, causing a failure\n\nCan also be reproduced locally with:\nnosetests-3.4 --with-marvin --marvin-config=setup/dev/advdualzone.cfg test/integration/component/test_mm_domain_limits.py:test_03_delete_vm -s -a tags=advanced\n\n### What to do about it?\n\nUpdate test_03_delete_vm in test/integration/component/test_mm_domain_limits.py to treat the CloudStack API errorCode 535 (memory resource limit exceeded) as an expected outcome, and only attempt VM deletion if creation succeeded. Example:\n\ntry:\n    vm = VirtualMachine.create(self.apiclient, ...)\n    vm_created = True\nexcept CloudstackAPIException as ex:\n    if \"errorCode: 535\" in str(ex) or \"Maximum amount of resources of Type = 'memory'\" in str(ex):\n        vm_created = False\n    else:\n        raise\n\nif vm_created:\n    vm.delete(self.apiclient)\n\nAlternatively, the domain/project memory limit could be raised in test setup if VM creation is expected to succeed in this test.","author":{"url":"https://github.com/PrashantBhanage","@type":"Person","name":"PrashantBhanage"},"datePublished":"2026-06-30T03:50:59.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/13516/cloudstack/issues/13516"}
