fails to create openvz vm

[leftys]

I tried to create a VM:

        virt { guest-openvz2:
          id => 102,
          virt_type   => 'openvz',
          ensure      => 'installed',
          os_template => 'debian-7.0-x86_64-minimal',
          memory      => 512,
          autoboot    => true,
          interfaces  => ["br0"]
        } 

and somehow, the agent tries to obtain the value of memory size before creating the vm and the config file. I obtained the following backtrace:

Debug: Executing '/usr/sbin/vzlist -1 -a -N guest-openvz2'

Can you check if you're able to reproduce the error by removing the id => 102 parameter?

Yes,

I have solved it by:

Maybe puppet behavior changed in v3 and it queries the values before creating the resource virt? I encountered a lot more problems, so I will do a pull request after I resolve them. (Now ip addreses are not assigned.)

Ehm. I had used the much older forge version. Now everything works. It would be nice to upgrade or delete it there, it didn't work for me at all...
