Setting up Oracle VM Manager 3.0.1
Steps to Setup OVM Environment
High Level Tasks
- Reinstall VMManager software / restore VM Manager DB
- Do ab-initio setup of vmserver
- Load templates
- Setup test VMs and shake out
Setup VM Manager
See Oracle_VM_Manager
Setup VM server for Server Pool and VM template Storage
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 .
$ cd /u01
$ 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
Configuring the VM Manager
Steps transcribed from Console record:
* 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)

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!
