02 Setting Cloud for IaaS

Overview

Now that the preparation work has been done, I am now ready to IAAS (Infrastructure as a Service) on my private cloud.

Procedure

4.1 Getting Started

Following the procedure in 4.1 Getting Started, I think I have all the necessary elements in place:

• OVM Manager has been installed on MELBOURNE.
• OVM Server has been installed on VICTORIA.
• Network Accessible Storage is available on NARRABRI.

4.1 Cloud Infrastructure Privileges

Since this is a test installation of a private cloud, I will skip over the procedure in 4.1 Cloud Infrastructure Privileges. There is no need for a sophisticated security model at this stage.

4.2 Registering the Oracle VM Manager

Enable Remote Log-Ins for OVMM

Following the procedure in 4.2 Registering the Oracle VM Manager, I discovered I had to enable remote log ins as described in 03 Enabling Remote Log Ins before I could proceed.

Update .bash_profile

On MELBOURNE, I added the following variables to ~/.bash_profile for oracle:

export JAVA_HOME=/u01/app/oracle/java export AGENT_INSTANCE_HOME=/u01/app/oracle/agent/agent_inst export OVM_MANAGER_HOME=/u01/app/oracle/ovm-manager-3

I set these variables as follows:

. ~/.bash_profile

Export OVMM Certificate

On MELBOURNE, I exported the OVMM certificate generated in 03 Enabling Remote Log Ins, as follows:

${JAVA_HOME}/bin/keytool -keystore ${OVM_MANAGER_HOME}/ovmmCoreTcps.ks -exportcert -alias ovmm -file /tmp/ovmm_cert

I entered the OVMM Key Store password when prompted as follows:

Enter keystore password: Certificate stored in file </tmp/ovmm_cert>

Import OVMM Certificate into OEM Agent

I used the following command to import the exported OVMM certificate into the key store for the OEM agent on MELBOURNE:

${AGENT_INSTANCE_HOME}/bin/emctl secure add_trust_cert_to_jks -trust_certs_loc /tmp/ovmm_cert -alias ovmm

I entered welcome when prompted below:

Oracle Enterprise Manager Cloud Control 12c Release 3 Copyright (c) 1996, 2013 Oracle Corporation. All rights reserved. Password: Message : Certificate was added to keystore ExitStatus: SUCCESS

Remove the Exported OVMM Certificate

On MELBOURNE, I cleaned up the exported OVMM certificate as follows:

rm -f /tmp/ovmm_cert

Deploy Virtualization Plug-In

I used the plug-in deployment procedure described in 15.4.7 Deploying Plug-Ins on Oracle Management Agent to deploy the Oracle Virtualization (12.1.0.5.0) Plug-In to the OEM agent on MELBOURNE only:

First Attempt to Register OVMM

I used the following parameters to register the OVMM on MELBOURNE:

The job failed with the following messages:

Diagnosis of Error

Yury Velikanov at Oracle VM Manager: OVMAPI_6000E Internal Error: Connection Refused says that:

If you see that error and try looking for a solution on Google, then unfortunately for you it is a very generic error message (a.k.a. ORA-600 in Oracle VM world ;) ) and you will need to dig a bit to find out what exactly is wrong in your case.

Following Yuri's advice, I ran the following command:

grep -i "error" /u01/app/oracle/ovm-manager-3/machine1/base_adf_domain/servers/AdminServer/logs/AdminServer.log

The results are:

wlw.logErrorsToConsole = false
