Parallels 10 & 1.2.2, Failed to mount folders

[pulkitjalan]

I have just upgraded to parallels 10 and the plugin to 1.2.2. The VMs don't start anymore. It did install Parallels Tools and reboot the vm before getting this error:

Failed to mount folders in Linux guest. This is usually because
the "prl_fs" file system is not available. Please verify that
Parallels Tools are properly installed in the guest and
can work properly. If so, the VM reboot can solve a problem.
The command attempted was:

mount -t prl_fs -o uid=`id -u vagrant`,gid=`getent group vagrant | cut -d: -f3`,dmode=775,fmode=755 var_www_html /var/www/html
mount -t prl_fs -o uid=`id -u vagrant`,gid=`id -g vagrant`,dmode=775,fmode=755 var_www_html /var/www/html

I also tried 1.2.0 with parallels 9 & 10, and im getting the same error with a slightly different message ("vboxsf" instead of "prl_fs").

I have got it working for now, running version 1.1.0 of the plugin with parallels 9 & 10.

Any idea what might be causing this issue?

You have set unsupported mount options to the synced_folder line in your Vagrantfile.
dmode, fmode - these options are specific Virtualbox, so Parallels Shared Folders doesn't support them.

It is working fine with previous provider version because there was another approach for synced folders. mount_options from Vagrantfile were just ignored and folders were mounted with default options.

So, having the latest provider version (>= 1.2.0), I suggest you to use this configuration section to define synced folder:

config.vm.provider "parallels" do |v, override|
  override.vm.synced_folder "<path_on_your_host>", "/var/www/html", mount_options: ["share"]
end

"share" is Parallels-specific option, meaning that each guest's user will have the same permissions as your host's user while accessing to this shared folder.
Also, please note that chown is not supporting for Parallels Shared folders yet [https://github.com//issues/103#issuecomment-51479461]

P.s. I defiantly should fill the documentation with all mount options supported by prl_fs. Will try to do it soon.

ah, I didn't realise those were virtual box specific. Thanks, that works now!

Thanks @legal90. Your example override works great.

For those coming along in the wake (like myself), note that "config" is misspelled as "convig" in the current example. No biggie, just make sure to change to the correct spelling or there'll be a big ugly stack output waiting for you when you run your Vagrantfile ;)

Oops, Sorry for that mistake 😦
Fixed.
