It just doesn\u0027t today.\n\nFinally also as we chatted, it might be nice to mention that instance owners may resize their existing legacy instance to a flavor with `hw:tpm_secret_security\u003dhost` in order to opt-in to live migration. This must be done by the instance owner rather than an admin because of Barbican secret ownership -- secrets are owned by the instance owner and by default the admin cannot read them. If the admin were to set up the appropriate ACLs in Barbican, then the admin could be able to do the resize themselves.","commit_id":"f1a58930283de0ad95fd980829ebf77b0f199d4e"},{"author":{"_account_id":8556,"name":"Ghanshyam Maan","display_name":"Ghanshyam Maan","email":"gmaan.os14@gmail.com","username":"ghanshyam"},"change_message_id":"37f01bdf2782e3c051e83d0b31aa8f00c9c277ac","unresolved":true,"context_lines":[{"line_number":31,"context_line":"    picks the best firmware file based on requested features (including Secure"},{"line_number":32,"context_line":"    Boot and AMD SEV), and supports additional firmware types like ROM."},{"line_number":33,"context_line":"  - |"},{"line_number":34,"context_line":"    Nova compute service now supports graceful shutdown (part 1 of a larger"},{"line_number":35,"context_line":"    effort).
