[one-users] OCCI: parsing bug, unsupported character?

[Daniel Molina]

Hi Marco,

I tried to reproduce the error with no luck. The VM is created without
any problem.

Would you mind to send us the content of the occi-server.log and the
list of gems you are using?
Also, can you check if a new VM is created in OpenNebula, even if
there is no response?

I have made some changes to the occi-server today, try using this last
version from the git repository.

Regards
