Procedure
Procedure
These commands are run on VICTORIA to set a paravirtualised (PV) virtual machine (VM) running under Xen.
Create VM Directory
Create VM Directory
On VICTORIA, the following command is used to create the directory containing the VM files:
mkdir -p /OVS/running_pool/AUBURN
Create Virtual Disk
Create Virtual Disk
On VICTORIA, the following commands are used to allocate a 5 GB virtual disk:
cd /OVS/running_pool/AUBURN dd if=/dev/zero of=root.dsk bs=4096 count=1310720
Note: If one follows the recommendation of disk space being 1.5 GB as given in Ubuntu Server (CLI) Installation, the following error appears during installation:
Generate HVM Configuration File
Generate HVM Configuration File
On VICTORIA, the following command is used to create a HVM configuration file. The VM is converted to PV image later on:

Start the Installation
The installation is started by creating the VM as follows:
xl create /OVS/running_pool/AUBURN/auburn.cfg
Follow the procedure in Install Ubuntu 16.04 LTS Server.
