James, I just filed a related bug which narrows down that this is happening if ceph-osd configures ssh key exchanges before nova-compute unit is added to the host.
https://bugs.launchpad.net/charm-nova-compute/+bug/1677707 This is also a Xenial Mitaka cloud, these nodes were added to a juju- deployer environment (Bootstack) manually by adding ubuntu charm to provision host, then ceph-osd add-unit, then nova-compute add-unit. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1624997 Title: live-migration fails because of " Host key verification failed" To manage notifications about this bug go to: https://bugs.launchpad.net/charm-nova-compute/+bug/1624997/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
