Title Cleanup: iptables/ipset chain existence not checked before deletion, causing misleading error logs ISSUE TYPE Bug Report COMPONENT NAME scripts/vm/network/security_group.py CLOUDSTACK VERSION main branch (4.22) SUMMARY When VM cleanup runs, the destroy_network_rules_for_vm() function attempts to flush and delete iptables chains and ipsets without first checking if they exist. The execute() function logs CalledProcessError at ERROR level with full traceback before re-raising, causing confusing duplicate log entries when chains don't exist. Exit code 1 from iptables/ipset is normal when a chain/set doesn't exist (idempotent cleanup), not a real error. STEPS TO REPRODUCE Create a VM with security groups in CloudStack Delete the VM Observe management server logs for the VM cleanup output EXPECTED RESULTS Cleanup should be idempotent - safe to run multiple times "Chain doesn't exist" should be logged at DEBUG level Only real errors should be logged at ERROR level No duplicate log
