Unable to start up parallels provider since Vagrant 1.9.5

[pieterjvrensburg]

I upgraded to version 1.7.4 and now I am unable to start up.

➜  centos-6.8 vagrant init parallels/centos-6.8; vagrant up --provider parallels

@pieterjvrensburg Hi! What Vagrant version do you use?
Try to reinstall the plugin:

vagrant plugin uninstall vagrant-parallels
vagrant plugin install vagrant-parallels

Does it help?

[legal90]

These issues look relevant:
hashicorp/vagrant#8593
hashicorp/vagrant#8594
hashicorp/vagrant#8595

[pieterjvrensburg]

I am running the latest, also updated before getting to this point.

➜  centos-6.9 vagrant --version
Vagrant 1.9.5

I have tried uninstalling and re-installing the plugin. Yesterday I uninstalled everything and started fresh, but will try the above suggestions.

Hi @legal90,

Thank you for the links, #8594 worked for me. This is what I did:

➜  centos-6.9 NOKOGIRI_USE_SYSTEM_LIBRARIES=true vagrant plugin install nokogiri 
Installing the 'nokogiri' plugin. This can take a few minutes...
Building native extensions.  This could take a while...
Installed the plugin 'nokogiri (1.7.2)'!

➜  centos-6.8 vagrant up --provider parallels 
WARNING: Nokogiri was built against LibXML version 2.9.4, but has dynamically loaded 2.9.2
Bringing machine 'default' up with 'parallels' provider...

I have libxml2 2.9.4 installed via Homebrew.

Is the warning something to worry about?

That issue was fixed by GH-298, the fix was released in vagrant-parallels v1.7.5.

How to use vagrant-parallels plugin with Vagrant v1.9.5

1. Remove it (if it was previously installed):

$ vagrant plugin uninstall vagrant-parallels

2. Install it with NOKOGIRI_USE_SYSTEM_LIBRARIES env variable defined:

$ NOKOGIRI_USE_SYSTEM_LIBRARIES=true vagrant plugin install vagrant-parallels

Done. After that vagrant-parallels plugin should work fine. The only thing you might be confused about is the LibXML warning like this one:

$ vagrant up
WARNING: Nokogiri was built against LibXML version 2.9.4, but has dynamically loaded 2.9.2
Bringing machine 'default' up with 'parallels' provider...
...

Just disregard this warning for now. It's caused by the difference between LibXML version bundled with Vagrant and the one installed on your macOS. However, it should not affect the plugin's operation.

UPDATE: The problem was solved in Vagrant 1.9.7:

$ vagrant plugin install vagrant-parallels
