This happens when VM's network VR is not running.\n`obfuscatePassword` method can be improved, and the password detail for the VM can be added with `display=false` so it doesn't end up in UserVmResponse.\n\n-------------\n\n### versions\n\n4.22.1, KVM Advanced zone but the issue could be preset for other configs as well\n\n### The steps to reproduce the bug\n\n1. Deploy a VM with a password enabled template\n2. Stop it\n3. Make sure VR for the network on which VM is deployed is not running\n4. Reset VM password without providing a password\n\n### What to do about it?\n\nFix the isssue","author":{"url":"https://github.com/shwstppr","@type":"Person","name":"shwstppr"},"datePublished":"2026-06-10T04:54:02.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/13387/cloudstack/issues/13387"}
