nfs mount problems

[thomasfb]

I oftenly got mount problems.

The duplicate exportfs entries appear reprodusably. But that seems not to be a real problem.

But a problem is that I'm using the exactly same Vagrantfile for an already installed machine and sometimes I get this error:

[default] Creating shared folders metadata...
[default] Exporting NFS shared folders...
Preparing to edit /etc/exports. Administrator privileges will be required...

Segfault is an independent bug as same as #57

[miurahr]

It is vagrant problem rather than vagrant-kvm.

There is vagrant/plugins/hosts/linux/host.rb don't check export host directory duplication but only check uuid duplication.
We need a fix in vagrant.
