Michael,
First is the nova service-list.
Second, thanks for the defect pointer - I have some further info - it seems
that this error about flavor not being found may be harmless…see below…
Third, I have some comments/questions about how to fix original problem of
"No valid host was found.”
ubuntu@ctl01:~$ nova service-list

I looked at the comments, and some of the error descriptions…
One thing that looked interesting was “open stack show flavor
<flavor-name>”…which didn’t work for one person, but worked for me:
ubuntu@ctl01:~$ openstack flavor show small
+----------------------------+--------------------------------------+
| Field | Value |
+----------------------------+--------------------------------------+
| OS-FLV-DISABLED:disabled | False |
| OS-FLV-EXT-DATA:ephemeral | 0 |
| access_project_ids | None |
| disk | 10 |
| id | f3eca419-5939-4a55-a00b-53b796978a11 |
| name | small |
| os-flavor-access:is_public | True |
| properties | |
| ram | 1024 |
| rxtx_factor | 1.0 |
| swap | |
| vcpus | 1 |
+----------------------------+--------------------------------------+
But yes, there’s an exception in there, even though the command succeeded as
far as I could tell.
So perhaps this flavor not found is an red-herring - not the real problem.
Note - I now see that this shows up all over my other working system’s
nova-api.log files.
Back to the original error, then, which is "No valid host was found. There are
not enough hosts available”
I’m hitting this problem whether I launch via heat and a heat template (that
works on my arm bare-metal pod, by the way, substituting the correct
architecture
I can dig some more - either on my own (maybe efficient, maybe not;) - or
perhaps this failure is interesting enough to debug…
The interesting question is whether the stable/euphrates virtual deploy with
MCP/Fuel should work or whether there is an issue (like some update broke
stable/E branch?).
OR whether it’s something to do with my deployment (see original message for
command line of deploy) or lack of proper preparation for the server on which
I’m running.
Also - let me know if you want to take this offline or retire to an IRC of your
choice.
And Lastly: I tried this with Master and hit some other issues that I can’t
remember, and thought master might be too risky - I just want a virtual pod
that I can run with, so either stable/E or master is good.
My point of the last comment is that if you’d prefer I join you in
chasing/debugging/trying things in Master (towards Fraser) than me asking you
for advice with Stable/E, I’m certainly open to that:)
Thanks much!
Joe
