OS-5999.md

SWSUP-665 has a description of the problem, basically:

  • OS-5950 fixed so we attempt to start metadata once we see the VM go 'running'
  • if qemu is up too slowly, it's possible we'll see 'running' before the socket is actually usable, in which case we'll get ECONNREFUSED
  • when we hit ECONNREFUSED on the initial connection, we rely on the periodic (every minute) retry
  • by the time we retry, Ubuntu zones with broken cloud-init (all of them, see IMAGE-1014) will get stuck and never properly recover

In order to work around this, we'll need to either:

  • have metadata retry after ECONNREFUSED, before the periodic timer
  • have some other mechanism that notifies metadata agent that the qemu socket is ready to be used
