provider_config disk options are ignored for Hyper-V

[afaonline]

Console output

vargrant up --provider hyperv

Bringing machine 'default' up with 'hyperv' provider...
==> default: Verifying Hyper-V is enabled...
==> default: Verifying Hyper-V is accessible...
Guest 'default' using provider 'hyperv' has provider specific config options for a provider other than 'hyperv'. These provider config options will be ignored for this guest

Expected behavior

I expect a Fixed primary disk to be created

Actual behavior

I tried to set "provider_config" for Hyper-V to make primary disk fixed, but it seems that Vagrant ignores the setting. Looks like it cannot extract the name of provider from disk configuration. I tried both ways to define the config:

  config.vm.disk :disk, size: "130GB", primary: true, provider_config: { "hyperv__Fixed" => true }

and

  config.vm.disk :disk, size: "130GB", primary: true, provider_config: { "hyperv" => {"Fixed" => true} }

In both cases I see "These provider config options will be ignored" in log, and disk is still Dynamic.

Vagrant version

  config.vm.communicator = "winrm"
  config.vm.disk :disk, size: "130GB", primary: true, provider_config: { "hyperv__Fixed" => true }
end

@yshingai thanks for your tip, also i was able to create hyperv vm with provider_config options after fixing args here: should be **

machine.provider.driver.create_disk(disk_file, disk_config.size, **disk_provider_config)
.....
machine.provider.driver.attach_disk(disk_file, **disk_provider_config)
