Can't login in an openvz created VPS using the API

Hello to everybody,

I'm developing the creation of VPS both qemu and openvz using the API. Everything seems right with qemu and openvz, and it creates the VPSs, but in the second case when I try to login the password of root is not matching.

new_container_settings:

I pass the password and it accepts, as I get no error, where can be the problem?

Thanks in advance.

Note that I have modified the IPs appeared, for security reasons ;-)
