Vagrant-LXC is a plugin that provides integration of Vagrant with LXC containers, a modern virtualisation technology native to Linux. To share files between the host and the container, NFS can be used. The Vagrant NFS plugin ensures that a NFS server runs at the host that exports predefined locations of the host’s filesystem. Sometimes, an error pops up when starting a Vagrant box, indicating that a timeout occurred and that starting the box failed.
A typical error is as follows:
mount.nfs: mount to NFS server '10.0.3.1:/path' failed: timed out, giving up
Which means that the connection is blocked, often due to the firewall. Another error might be something like:
mount.nfs: access denied by server while mounting 10.0.3.1:/path
This practically means that the container is not allowed to reach the NFS server of the host, often due to AppArmor policy. I experienced this issue some time ago and discussed it in an issue at Github.

Keeping Magento shops up to date is important to reduce their vulnerability. Sometimes, security updates introduce breaking changes. The recent Magento update, version 188.8.131.52, includes such a breaking change that can cause blank pages on the front-end and back-end. This is caused by the way in which Magento handles symlinks.
When blank pages occur, take a look at Magento’s system.log file. You might find entries like the following:
2017-07-20T20:53:05+00:00 CRIT (2): Not valid template file:frontend/theme/default/template/page/2columns-right.phtml
2017-07-20T20:55:48+00:00 CRIT (2): Not valid template file:adminhtml/default/default/template/mstcore/toolbar.phtml
