Conoha で Vagrant up できない問題の解決策

Install

最新の vagrant を入れる

wget https://dl.bintray.com/mitchellh/vagrant/vagrant_1.6.3_x86_64.deb
sudo dpkg -i vagrant_1.6.3_x86_64.deb
apt-get install virtualbox

vagrant box を入れて初期化 (Ubuntu 14.04)

vagrant box add trusty64 https://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-amd64-vagrant-disk1.box

mkdir Vagrant
vagrant init trusty64

vagrant up

The guest machine entered an invalid state while waiting for it
to boot. Valid states are 'starting, running'. The machine is in the
'poweroff' state. Please verify everything is configured
properly and try again.

If the provider you're using has a GUI that comes with it,
it is often helpful to open that and watch the machine, since the
GUI often has more helpful error messages than Vagrant can retrieve.
For example, if you're using VirtualBox, run `vagrant up` while the
VirtualBox GUI is open.

解決策

原因究明方法

1. ssh -X で conoha の vps にログインして、X を飛ばせるようにする
2. virtualbox で GUI 立ち上げ
3. GUI から Start ボタンを押して起動を試す。 たぶんここでこけてる。

原因

VT-X がないから失敗していた。
GUI から Setting --> System --> Acceleration --> Enable VT-X のチェックを外す
