Overview

The VM under VirtualBox has proven to be unstable with several crashes. I have decided to move GORDON to VICTORIA . This means that VICTORIA will now be restricted to running a maximum of three (3) VM images:

  1. CRONULLA with a memory allocation of six (6) GB
  2. GORDON with a memory allocation of four (4) GB
  3. PERSONAL with a memory allocation of four (4) GB

This accounts for 14 GB out of 15 GB (one (1) GB is needed for XEN supervisor). Thus, RAC will have to move elsewhere.

Procedure

Allocate VM Resources

In Victoria VM Resources , the resource allocations are made:

  • MAC address of 00:16:3E:00:00:19
  • VNC Console address of 6
  • CD-ROM V100082-01.iso mounted for Oracle Enterprise Linux Version 7.2 (OEL7U2)

Create VM

Allocate Disk Space

On VICTORIA , the following commands are run as root to create the directory and disk files for GORDON : 

mkdir -p /OVS/running_pool/GORDON/
cd /OVS/running_pool/GORDON/
dd bs=1G count=50 if=/dev/zero of=root_disk
dd bs=1G count=20 if=/dev/zero of=data_disk
dd bs=1G count=30 if=/dev/zero of=fra_disk

Create XEN Configuration File for GORDON

On VICTORIA , the following commands are run as root to create the XEN configuration file for GORDON : 

cd /OVS/running_pool/GORDON/
cat gordon.hvm <<DONE
