nova.exception.ProcessExecutionError: Unexpected error while running command.
Command: openssl ca -batch -out /tmp/tmphMeLeD/outbound.crt -config ./openssl.cnf -infiles /tmp/tmphMeLeD/inbound.csr
Exit code: 1
Stdout: None
Stderr: None

but running openssl ca -batch -out /tmp/tmphMeLeD/outbound.crt -config ./openssl.cnf -infiles /tmp/tmphMeLeD/inbound.csr is succesfull, the problem there is that i don't have the .zip file and this is needed
in order to have VMs working.

advice appriciated.
