[one-users] Fwd: Re: showstopper -- can't create VMs after upgrade to OpenNebula 4.4

Tue Dec 10 14:36:48 PST 2013

Already did all that...  "sealion" is just an alias in /etc/hosts, for sealion.ine.corp.

Perhaps this StackEx note, is related to my issue??   With the ONE (ruby) command "clone"?
    http://unix.stackexchange.com/questions/37884/how-to-copy-with-scp-between-two-servers-using-key-auth

Here's my failure, on another attempt  --  onevm delete --recreate 62

Tue Dec 10 17:32:30 2013 [TM][E]: clone: Command "scp -r sealion.ine.corp:/var/lib/one/datastores/1/20288f3556d15e65b1dfdc540a450226 sealion.ine.corp:/var/lib/one//datastores/0/62/disk.0" failed: Permission denied (publickey,keyboard-interactive).

Tue Dec 10 17:32:31 2013 [DiM][I]: New VM state is FAILED
Should the "clone" ing create a *source hostname* for the scp command (as above), and why?  How would the ssh pubkey authentication work, in this case??   (If I drop the "source hostname" in the scp command above, the scp works fine...)

Thank you for your assistance,

Ok, I was mislead by the manual clone output and that of vm.log. So yes it is a permission problem.

In your tests you are using

oneadmin at sealion:~/vms > ssh oneadmin at sealion

BUT the name of the host is sealion.ine.corp

Can you double check with the same hostname, just in case you are not facing a hostname resolution issue.

Cheers

Hello Ruben, thanks much for the quick! response:

These look fine to me, other than missing folders under datastores (by VM id), when the clone command runs...

Not sure how to do that, here's the configs.  I have not "touched" the Datastores configs, ever - other than by creating VMs, I suppose.

Hello ONE team,

So... after the upgrade to 4.4 OpenNebula on openSuse Linux 12.3
(x86_64), I can no longer create VMs.

The log seems to indicate a SSH login-failure (requiring passsword?)

Seen below at the end of this message, it's clear that 'oneadmin' user
can do passwordless logins...

Please let me know what may be going on; the log is not that
informative.  I did run (as 'oneadmin') the Ruby/ONE "clone" command by
hand, with the results, below...

(thanks in advance for any insights - this is a *showstopper*...)
