I Don’t Think This Means What You Think It Means: Red Herrings in OpenStack
summary
Three concrete OpenStack gotchas and their fixes: Neutron HA router VRIDs are 8‑bit so VRID is 8‑bit (max 255 HA routers) — hit that hard limit and must spread HA routers across tenants or change policy to let users disable HA; Magnum returns HTTP 400 when a private image lacks the required metadata, so set image property os_distro to the correct value; Heat can throw a spurious UTF‑8 500 from string_replace collisions — change parameter prefix (e.g. to % ) to avoid the decoding error.
