Overview

I am continuing on from 03 Setting Cloud for IaaS 2 to set up a private cloud.

Procedure

Setting Up File Shares

Two (2) file shares are registered on NARRABRI :

  1. OEM_Staging for the staging area used by OEM
  2. OVM_Repository for the repository used by OVM

Settings for OEM_Staging

Only NFS is enabled with read/write access by any host for OEM_Staging , as shown below:


And anyone can read and write to the NFS share as shown below:


Settings for OVM_Repository

The settings for OVM_Repository are the same as for OEM_Staging .

4.9 Registering Storage Servers

Followed the procedure in 4.9 Registering Storage Servers to set up NFS and iSCSI.

4.9.1 Registering the File Server

As described in 4.9.1 Registering the File Server , I registered a File Server on NARRABRI with the following parameters:

Parameter Name Parameter Value
Name Narrabri NFS
Plugin Name Oracle Generic Network File System
Admin Host
Admin Username
Admin Password
Access Host narrabri.yaocm.id.au
Uniform Exports Yes
Admin Servers victoria.yaocm.id.au
Refresh Servers

Two (2) NFS shares are exposed:


Note: For each exposed share, I also did a Refresh operation by selecting the share first then clicking on the Refresh button. This is needed to be done so that the creation of the storage repository can proceed.

I also added the following comments for each share (via the Edit button):

Name Description
nfs:/data/OEM_Staging Staging area for patches and software used by OEM
nfs:/data/OVM_Repository OVM repository

4.9.2 Registering the Storage Array

Following the procedure in 4.9.2 Registering the Storage Array , I registered an array of iSCSI LUNs as follows:

Parameter Name Parameter Value
Name Narrabri SAN
Admin Host
Admin Username
Status online
Plugin Name Oracle Generic SCSI Plugin
Description iSCSI LUNs on Narrabri
Extra Information
Total Size (GB) 0.00
Free Size (GB) 0.00
Validated Yes
Use CHAP No

However, the problem is that there are no physical disks in this storage array:


I will leave this mystery until later.

4.10 Creating a Storage Repository

Following the procedure in 4.10 Creating a Storage Repository , I created the storage repository with the following details:

Parameter Name Parameter Value
Name OVM_Repository
Storage Type Network File System
Location nfs:/data/OVM_Repository

The result is as follows:


The storage details for the Narrabri NFS now looks like:


4.11 Presenting the Storage Repository

Following the procedure in 4.11 Presenting the Storage Repository , I ended up with the following result:


4.12 Using Self Update to Download Oracle VM Templates and Virtual Assemblies

Following the procedure in 4.12 Using Self Update to Download Oracle VM Templates and Virtual Assemblies , I downloaded and applied Oracle Linux OL6.2 for x86_64 PVM as shown below:


4.13 Importing Assemblies, Templates, and Virtual Disks into the Storage Repository

Following the procedure in 4.13 Importing Assemblies, Templates, and Virtual Disks into the Storage Repository , I tried to import into Assembly from Software Library Component as shown below:


It looks like I skipped a step somewhere as I got the following error message:


(This is done in 4.16.4 Configuring the Software Library User with External Management Agent below.)

However, I was able to import an ISO image from the Software share that I created on NARRABRI which is accessible at ftp://?uname?:?pwd?@narrabri.yaocm.id.au/Software/V41362-01.iso (where ?uname? and ?pwd? are replaced by the appropriate username and password for access to the NARRABRI NAS. The result is shown below:


4.14 Creating a Virtual Server Pool

Following the procedure in 4.14 Creating a Virtual Server Pool , I created a single pool as I only have one (1) VM server: VICTORIA .

First, I created a new NFS share on NARRABRI called Victoria_Share using a similar procedure described above. I ran a discovery on Narrabri NFS to discover all shares, and then:

  1. Ran a refresh on nfs:/data/Victoria_Share —successful
  2. Tried to delete nfs:/data/Software —failed with the following message:
    3. oracle.sysman.vt.ovm.integration.api.EMOVMCommunicationServiceException: 5047: Error while performing the operation: Commiting the ovm job EM_DeleteFileSystem_nfs:/data/Software_2014-06-09_16-52-02-664 failed.[com.oracle.ovm.mgr.api.exception.RuleException:OVMRU_002013E: File system delete is not supported by generic plugin associated with this file server : Narrabri NFS. [Mon Jun 09 16:52:02 EST 2014]]

The final status of the file systems on Narrabri NFS is:


I created a virtual server pool with the following settings:

Parameter Name Parameter Value
Virtual Server Pool Name Home
Description Home Server Pool
Keymap en-us (English, United States)
VM Start Policy Start on Best Server
Secure VM Migrate No
Activate Cluster No
Cluster Timeout (sec) NA
Type of Pool File System NA
Location NA
Virtual IP 192.168.1.105
Virtual Servers victoria.yaocm.id.au

Note: The Virtual IP address has to be on the same subnet as the pool VIP, otherwise the following message is raised:

Error when invoking OVM API oracle.sysman.vt.ovm.integration.api.EMOVMCommunicationServiceException: 2002: Error while performing the operation: Commiting the ovm job EM_AddServer_victoria.yaocm.id.au_ToPool_Home_2014-06-09_17-11-28-974 failed.[com.oracle.ovm.mgr.api.exception.RuleException:OVMRU_000030E Cannot add server: victoria.yaocm.id.au, to pool: Home. Server Mgt IP address: 192.168.1.100, is not on same subnet as pool VIP: 192.168.2.1. [Mon Jun 09 17:11:29 EST 2014]]

Updated IP Addresses to register 192.168.1.105 as being used.

4.15 Creating a Zone

Following the procedure in 4.15 Creating a Zone , I created a zone with the following settings:

Parameter Name Parameter Value
Name Zealand
Description VM Zone for Melbourne
Infrastructure Cloud Self Service Zone Yes
Virtual Server Pools Home

4.16.3 Configuring the Software Library User

Following the procedure in 4.16.3 Configuring the Software Library User , I granted view access to the named credential called HOST_ORACLE (which is the credential used by the oracle user to access hosts). The result is as follows:


4.16.4 Configuring the Software Library User with External Management Agent

Following the procedure in 4.16.4 Configuring the Software Library User with External Management Agent , CLOUD_SWLIB_USER is granted Execute privileges on melbourne.yaocm.id.au . The result is as follows:


Import OEL 6U2 Assembly

With CLOUD_SWLIB_USER set up correctly, I am now able to import the downloaded assembly, Oracle Linux OL6.2 for x86_64 PVM , by following the procedure in 4.13 Importing Assemblies, Templates, and Virtual Disks into the Storage Repository . I ended up with the following new components:


This assembly consists of one (1) VM Template:


This VM Template has one (1) Virtual Disk:


Other Steps

I did not set up the following options:

  • Setting Up the Storage Quality of Service (QoS)
  • Patching the Oracle VM Server
  • Acknowledging OVM Events
  • Managing the NTP Configuration
  • Importing Virtual Machines
  • Acknowledging the Repository Events
