Once this is done, users can log into the VM with their private keys as usual (see [[ssh keys]]). | Once this is done, users can log into the VM with their private keys as usual (see [[ssh keys]]). | ||
=Downloading an image into a local VirtualBox= | |||
The first step is to install the glance client. If you don't have pip get it with | |||
{{Command|sudo apt-get install python-dev python-pip}} | |||
note that this is the command on Ubuntu/Debain other Linux flavors will have similar but different commands see [http://docs.openstack.org/user-guide/common/cli_install_openstack_command_line_clients.html]. Then install the client with | |||
{{Command|pip install python-glanceclient}} | |||
As mentioned in the [[OpenStack#Command Line Clients]] section you will need to download the OpenStack RC file and source it. Glance can list the available images on your OpenStack account with | |||
{{Command|glance image-list}} | |||
producing something like: | |||
+--------------------------------------+---------------------------------------+-------------+------------------+-------------+--------+ | |||
| ID | Name | Disk Format | Container Format | Size | Status | | |||

You can then download a particular image with | |||
{{Command|glance image-download --file ./<file-name-for-image>.qcow2 2c751755-854d-49c3-af82-d501e51e7159}} | |||
where the last argument is the <code>ID</code> of the image you wish to download taken from the table listed with the <code>glance image-list</code> command. For more detailed instructions on the above steps see [https://raymii.org/s/tutorials/Openstack_Glance_Image_Download.html]. | |||
Then to use this image in VirtualBox you will need to convert the image in the qcow2 format to the vmdk format. This can be done with the <code>qemu-img</code> tool. This can be installed with something like | |||
{{Command|sudo apt-get install qemu-img}} | |||
then do the conversion with | |||
{{Command|qemu-img convert -f qcow2 vdisk.qcow2 -O vmdk vdisk.vmdk}} | |||
Then you can create a new vritual machine and attach the vmdk image to it see [http://techathlon.com/how-to-run-a-vmdk-file-in-oracle-virtualbox/] for detailed instructions on this. | |||
