ssh issue when provisioning box with vagrant 1.8.1

Issue Background

The prerequisites for the Linux host (https://wiki.linuxfoundation.org/civilinfrastructureplatform/ciptestingboardatdesksingledevfeaturepage) state Vagrant 1.8.1 or better. Ubunutu 16.04 apt sources default to 1.8.1 . However vagrant up fails.

Issue description

The error 'mesg: ttyname failed: Inappropriate ioctl for device' leads to the appropriate ssh connection not being able to be established during provisioning stage (kernelci ansible etc). Searching for this error leads to various vagrant-VB projects with users witnessing the same issue. Manually upgrading to a minimum version of vagrant 1.9.1 (wget/dpkg) remedies the issue. Install vb guest additions on host is also recommended but not clear as to if needed.

Acceptance criteria

• Change prerequisite criteria on wiki to state vagrant min version as 1.9.1
