 See [[Installing Oracle VM Manager]]

==Setup VM server for Server Pool and VM template Storage==

<pre>
  i)  Run the installation process using the Oracle VM Server 3.0.x 

        Variations:

          - Don't forget to attach the balance of the boot disk as /u01 and set FS type to 'oscfs' (?)
          - 

  ii) Once setup run through the fllowing to finalize the instance in preparation for configuring the VM manager

         - Export Server Pool partition

           $ echo "/u01/serverpool \*(rw,no_root_squash)" > /etc/exports
           $ cat /etc/exports
           $ cd /u01
           $ ls -ld .
           $ chmod 777 .
           $ mkdir serverpool
           $ chmod 777 serverpool
           $ ls -l
           $ exportfs -av
           $ exportfs -v

         - Start NFS and configure to start on boot

           $ service nfs status
           $ service nfs start
           $ chkconfig nfs on
       
           and check:

           $ mount -t nfs vmserver:/u01/serverpool /mnt
           $ mount
           $ umount /mnt mount

         - Check firewall is diabled

           $ service iptables status
           $ service ip6tables status
</pre>

==Configuring the VM Manager==

Steps transcribed from Console record:

<pre>
       * Discover Server 192.168.100.151
       * Edit Server vmserver.pha.com.au
       * Register File Server OvmNfsServer
       * Refresh File System nfs:/u01/serverpool (Failed - ???
      
         So attempte3d recovery

         ~ Delete nfs:/u01/serverpool
         ~ Delete OvmNfsServer

       * Register File Server OvnNfsServer
       * Refresh File Server OvnNfsServer
       * Refresh File System nfs:/u01/serverpool

       Attempted to use the QNAP as iSCSI - don't know how yet!

       * Refresh Storage Array - Unmanaged iSCSI Storage Array (Failed - did not know what to do...)

       * Refresh File System nfs:/u01/serverpool
       * Edit Physical Disk SATA_ST31000340AS_9QJ1CNFX (Make it sharable!)
       * Create Server Pool OvmServerPool
       * Add Server vmserver.pha.com.au to Server Pool OvmServerPool	(Failed)

       ...backtrack...

       * Delete OvmServerPool
       * Rescan Physical Disks on Server vmserver.pha.com.au. Use this command when storage array disks have been added or removed from a server.	
       * Edit Physical Disk SATA_ST31000340AS_9QJ1CNFX (Make it sharable)
       * Refresh File System nfs:/u01/serverpool
       * Rescan Physical Disks on Server vmserver.pha.com.au. Use this command when stor
       * Refresh File System nfs:/u01/serverpool
       * Add Server vmserver.pha.com.au to Server Pool  (Aborted)

       * Create Server Pool OvmServerPool
       * Edit Server Pool OvmServerPool
       * Add Server vmserver.pha.com.au to Server Pool OvmServerPool (Failed)

           DNS issue - vmserver.pha.com.au was mapped to 127.0.0.1 in hosts file -
           removed this and it worked on the next attempt

       * Add Server vmserver.pha.com.au to Server Pool OvmServerPool (Worked this time)
       * Create Repository OvmRepository
       * Edit Server Pool OvmServerPool
       * Discover Repository
       * Present Repository OvmRepository to Server vmserver.pha.com.au

       * Import Template OvmRepository (Failed)

         - had http://localhost/... and not http://vmmanager.pha.com.au/... in URL for template source [changed and it worked]

       > Refresh Repository OvmRepository (does this automatically after import)
       * Import Template OvmRepository - Unpacking Template 1/1, 27,717 MB/? MB	[11G]
       > Refresh Repository OvmRepository
       * Import Template OvmRepository - Unpacking Template 1/1, 26,954 MB/? MB	[10G]
       > Refresh Repository OvmRepository
       * Import Template OvmRepository - Unpacking Template 1/1, 2,466 MB/? MB	[Linux]
       > Refresh Repository OvmRepository

       *DONE*

     Missing steps in above sequence:

       * Set up NIC MAC addresses
       * Extend network to be used for Data and VMs themselves 

     Test it:

       * Clone Ora11G from OVM_EL5U2_X86_64_ORACLE11G_PVM.tgz (Appeared to work - but failed to start/run)
       * Create Virtual Machine Oracle11G (Appeared to work - but failed to start/run)
       * Edit Virtual Machine Ora11G
       * Start Virtual Machine Ora11G (Failed)
</pre>

</pre>

Note: Network is not properly set up!  I missed the point where one needs to put in IP range for VMs to use (192.168.100.160 - 169)!

Did not manage to work out where to do this.

A rough draft - though I would use this as a starting point for the next pass!
