Release for CentOS Linux 7 x86_64 Vagrant Box

We are pleased to announce the immediate availability for CentOS Linux 7
x86_64 images for Vagrant.

This image represents a minimal install set, that lines up with the user
expectation for our Cloud Images, our ISO based Minimal installer and
the default minimal install profile from the in-distro install options.

Images are released for the VirtualBox and LibVirt providers ( more
providers coming soon ). They are also available on the Vagrant Cloud /
Atlas service at : https://atlas.hashicorp.com/centos/boxes/7

Anyone using vagrant already can get started with the following two
commands :

vagrant init centos/7
vagrant up

--------
The backing files are available for direct download at :
* LibVirt:
http://cloud.centos.org/centos/7/vagrant/x86_64/images/CentOS-7-Vagrant-1505-x86_64-01.LibVirt.box
sha256: 49ac77893c1609d9d79b1b3f1fd0526d77a01cb62563c7c507099c5ab785a6f1

* VirtualBox:
http://cloud.centos.org/centos/7/vagrant/x86_64/images/CentOS-7-Vagrant-1505-x86_64-01.box
sha256: 572c5ce3fc4e1a1efe274f5c30bc1645240bf1702fcdcd1976e67988d04df001

* Generic Qcow2:
http://cloud.centos.org/centos/7/vagrant/x86_64/images/CentOS-7-Vagrant-1505-x86_64-01.qcow2
sha256: 70e703fa22f09dd0257bfe0e625a33f3cf2d7a98d5264ac75fdf1aa06336d1b3

Note: this generic qcow2 file is pre-seeded with the vagrant user, and
can be used to setup backing instances for more providers.

--------
If you intend to hardcode urls into automation scripts etc, I highly
recommend using the short link urls, these point at the latest released
image set and will be updated when backing media is updated for security
issues, bugfix, feature upgrades.

all security, bugfix, enhancement and general updates for CentOS Linux,
in this case they include updates up to and including May 28th, 2015.
