Prerequisites

Create a JSON-File which has the following mandatory fields and change it to you needs:

{
    "rhevm"     : "hostname-fqdn",
    "profile"   : "profile",
    "ca_file"   : "ca.pem",
    "vms"       : [
        {"hostname"     : "rest-api-1.int",
        "cluster"       : "Default",
        "template"      : "Blank",
        "storage-domain": "storage-domain",
        "memory"        : 5,
        "disks"         : {
            "rest-api-1.sys"    :  30
        },
        "interfaces"    : {
            "nic1"    : "network1",
            "nic2"    : "network2"
            }
        },
 
        {"hostname"     : "rest-api-2.int",
        "cluster"       : "Default",
        "template"      : "Blank",
        "storage-domain": "storage-domain",
        "memory"        : 5,
        "disks"         : {
            "rest-api-2.sys" : 35
        },
        "interfaces"    : {
            "nic1"  : "network2",
            "nic2"  : "network3"
            }
        }
    ]
}

Note: Memory and disks parameter are in GB Note: If you use a template, which sets specific attributes like nics the tool may not work. For test purposes use template "Blank".

In order to authenticate at the rhevm you will need a ca-file. Usually you get this ca-file under /etc/pki/ovirt-engine/ on the rhevm. Place the ca-file in the same directory where the tool is located.

Usage

The tool needs to be executed with sudo.

[user:host]$ sudo python rhev-create-vm -c example.json
Password:
=================[ AUTHENTICATING TO RHEVM ]=================
Connecting to "https://rhevmint/ovirt-engine/api" as "user@profile".


=================[ CREATING VMS ]=================
Created VM "rest-api-1.int" on cluster "Default" with template "Blank".
Created VM "rest-api-2.int" on cluster "Default" with template "Blank".


=================[ ADDING NICS ]=================
Adding logical network "network1" to "rest-api-1.int" as NIC "nic1".
Adding logical network "network2" to "rest-api-1.int" as NIC "nic5".
Adding logical network "network2" to "rest-api-2.int" as NIC "nic1".
Adding logical network "network3" to "rest-api-2.int" as NIC "nic5".


=================[ ADDING DISK ]=================
Adding Disk "rest-api-1.sys" with 30 Gb to "rest-api-1.int".
	Waiting for Disk to come up...
	Disk ready.
Adding Disk "rest-api-2.sys" with 35 Gb to "rest-api-2.int".
	Waiting for Disk to come up...
	Disk ready.


=================[ BOOTING VMS OVER NETWORK ]=================
Booting "rest-api-1.int".
Booting "rest-api-2.int".


=================[ VIRTUAL MACHINES ]=================
