Provisioning Guests Manually

Provisioning a guest with multiple virtual disks

You can provision a guest with multiple virtual disks specifying different images and different boot orders.

The following example shows how to install and configure a guest with two different virtual disks, disk 1 and disk 2. The guest parameters are:
  • Unique name of the guest: a-guest.
  • Number of CPUs: 2.
  • Amount of RAM: 2048 MB.
  • Location of image1 for disk 1: /var/lib/libvirt/images/image1.qcow2
  • Location of image2 for disk 2: /var/lib/libvirt/images/image2.qcow2

To install and configure a guest, perform the following steps in configuration mode.

Table 1. Provisioning a guest manually
Step Command
Create a guest called a-guest. 
vyatta@vyatta# set virtualization guest a-guest
Assign the UUID to the guest. 
vyatta@vyatta# set virtualization guest a-guest uuid b7bbf124-7314-21e2-819f-fef8119cd991
Set the number of CPUs as 2. 
vyatta@vyatta# set virtualization guest a-guest cpus 2
Set the RAM as 2048 MB. 
vyatta@vyatta# set virtualization guest a-guest memory 2048
Set a virtual disk for the guest as disk 1. 
vyatta@vyatta#  set virtualization guest a-guest devices disk 1 device-type disk
Set the path of the image for disk 1 as /var/lib/libvirt/images/image1.qcow2. 
vyatta@vyatta# set virtualization guest a-guest devices disk 1 source file /var/lib/libvirt/images/image1.qcow2
Set the boot order for disk 1 as 1. 
vyatta@vyatta# set virtualization guest a-guest devices disk 1 boot-order 1
Set another virtual disk for the guest as disk 2. 
vyatta@vyatta#  set virtualization guest a-guest devices disk 2 device-type disk
Set the path of the image for disk 2 as /var/lib/libvirt/images/image2.qcow2. 
vyatta@vyatta# set virtualization guest a-guest devices disk 2 source file /var/lib/libvirt/images/image2.qcow2
Set the boot order for disk 2 as 3. 
vyatta@vyatta# set virtualization guest a-guest devices disk 2 boot-order 3
Set the display password as vyatta123. 
vyatta@vyatta# set virtualization guest a-guest devices display password vyatta123
Set the display port as 5911. 
vyatta@vyatta# set virtualization guest a-guest devices display port 5911
Set the remote connection display access as vnc. 
vyatta@vyatta# set virtualization guest a-guest devices display connection-type vnc
Commit the changes. 
vyatta@vyatta# commit
Display the result. 
vyatta@vyatta#
