How to create a vdisk

A vdisk that will be attacched to the VM
[root@oda11 ~]# oakcli create vdisk pignadiskl -repo shared1 -size 5G -type local

How to create a cpupool

The same pool name must be configured on each node.
[root@oda12 ~]# oakcli create cpupool provapool -numcpu 2 -node 1
[root@oda12 ~]# oakcli create cpupool provapool -numcpu 2 -node 0

How to configure the VM

Add two network interfaces

[root@oda11 ~]# oakcli configure vm pigna -network "['type=netfront,bridge=net1','type=netfront,bridge=net2']"

Enable failover

[root@oda11 ~]# oakcli configure vm pigna -failover true

Attach an additional disk

[root@oda11 ~]# oakcli modify vm pigna -attachvdisk pignadiskl

Configuring cpupool

[root@oda11 ~]# oakcli configure vm pigna -cpupool provapool

Starting the VM

[root@oda11 ~]# oakcli start vm pigna

Attacching to the console

You must ssh to the ODA_BASE using -Y flag.
[root@oda11 ~]# oakcli show vmconsole pigna
A VNC session will start

Expanding the disk space from inside the VM

This is the vdisk created before.
[root@pigna ~]# btrfs device add /dev/xvdb /
You can attach additional vdisks, and the VM OS will see them without the need to reboot it.
