I had the occasion recently to deploy an OVM stack at a customer site.  Initially it was my intention to only deploy Enterprise Manager 12c and take advantage of the cloud control features within.  As it turned out, this provides merely a "remote control" function of an existing OVM Manager.  With this in mind, I could not find many advantages to using EM12c for Oracle virtual machine management. The next hurdle was with the hardware.  Of course, the physical servers we deployed the OVS 3.1.1. hyper-visor on were not "Oracle Certified."  Specifically DELL PowerEdge M620 Blade Servers.  ( http://www.dell.com/us/enterprise/p/poweredge-m620/pd?~ck=anav ) The customer had selected the Broadcom®  57810S-k Dual Port 10Gb KR blade NDC on board Network Adapter as well as the Mezzanine Broadcom 5719 Serdes Quad Port 1Gb providing a total of 6 ethernet ports, two of them 10GB. The storage array is Equalogic iSCSI SAN.  (S...

Oracle Virtual Machine (OVM) 3.1.1. was released on the 8th May 2012 and finally it's supported on VirtualBox.  This is great news for anyone who wants to give installing an OVM Lab a go. I gave it a go. I created 3 VirtualBox guests: Openfiler for iSCSI with a 40GB virtual disk for chopping up into LUNs and iSCSI. Oracle Linux 6.0 on which I installed OVM 3.1.1. in Demo mode.  This guest has 4GB of RAM assigned to it and a 25GB HD.  Probably a bit big, but OVM is a large application with an Oracle XE database and Oracle Weblogic services installed, I thought better safe than sorry. Oracle Virtual Server 3.1.1.  This guest had just a 4GB HD and 1536MB of RAM which I figured would be just enough to get 1 virtual machine up and running on it. My VirtualBox is configured with a couple of host only networks: vboxnet0 => 192.168.56.0/24 => Management network.  I also have dnsmasq configured on this network to serve IP addresses via DHCP to clients o...
