Building a Dell OS10 Vagrant Libvirt Box

Dell OS10 is supported by the netlab libvirt package command.

Warning

  • Dell provides the OS10 Virtual image as a set of vmdk and gns3a files to be used within GNS3. The following procedure will “convert” the required files for using them with Vagrant.

  • If you’re using a ‌netlab release older than 1.8.2, or if you’re using a Linux distribution other than Ubuntu, please read the box-building caveats first.

To prepare for the build:

  • Download OS10 files into /tmp directory

  • Create an empty directory on a Ubuntu machine with libvirt and Vagrant.

  • Convert these vmdk files into qcow2 format with qemu-img utility:

    • OS10-Disk-1.0.0.vmdk

    • OS10-Installer-<VERSION>.vmdk

    • OS10-platform-<PLATFORM>-<VERSION>.vmdk

qemu-img convert -O qcow2 /tmp/OS10-Disk-1.0.0.vmdk OS10-Disk-1.qcow2
qemu-img convert -O qcow2 /tmp/OS10-Installer-10.5.3.4.108.vmdk hdb_OS10-installer.qcow2
qemu-img convert -O qcow2 /tmp/OS10-platform-S5224F-10.5.3.4.108.vmdk hdc_OS10-platform.qcow2

To build a Dell OS10 box based on the above install image:

  • Execute netlab libvirt package dellos10 OS10-Disk-1.qcow2 and follow the instructions

Initial Device Configuration

During the box-building process you’ll have to copy-paste initial device configuration. netlab libvirt config dellos10 command displays the build recipe:

Creating initial configuration for Dell OS10
=============================================

* Wait for the 'login' prompt, and then wait again some more minutes
* Login as 'admin' (password: 'admin')
* Disable zero-touch ('ztd cancel')
* Enter configuration mode ('configure')
* Copy-paste the following configuration

NOTE: the management traffic is isolated in a dedicated management VRF (management).

===============
*** WARNING ***
===============
To disable zero-touch (ZTD) a full reload is required after the first configuration.
