Thank you for taking the time to report this bug and helping to make
Ubuntu better.
It's not clear to me if this would be an issue with openssh, lxc or
cloud-init. But I was unable to reproduce your issue.
I had to make a couple of amendments to your instructions.
First, I presume your lxc-attach is run in a separate terminal to the
ssh command (ie. you're trying to ssh from the host, and not the
container)?
Second, `dig @10.0.3.1 base` didn't work for me. Instead, I used "lxc-
info -n base" to look up the IP address of the container.
Apart from this, I was unable to reproduce the issue. I do see "error:
Could not load host key: /etc/ssh/ssh_host_ed25519_key" but this does
not appear to affect anything:

It looks like my cloud image is current, but it does not include
openssh-server 1:6.6p1-2ubuntu2.
Please could you try to reproduce again on a fresh instance, to verify
that nothing has changed? Also, please report the cloud image build
information as well as the package versions you have of openssh-server
and cloud-init as above. Marking Incomplete in the meantime, since I
cannot reproduce with the instructions given. Please change back to New
when done. Thanks!
** Changed in: openssh (Ubuntu)
Status: New => Incomplete
