[ovirt-devel] Unable to start vm on specific host via ruby sdk

[Marc Young]

Using the ruby sdk I'm unable to start a VM on a specific host.

According to the API docs at api/v4/model#types/vm_placement_policy :


Name Type
----------------
hosts Host[]


No matter what I specify, I run into this same bug:

The same goes with giving an object instead of a hash object

=> 68:           machine.start(
   69:             use_cloud_init: true,
   70:             vm: vm_configuration
   71:           )
