Oracle VM

A bit of interesting news I thought worth posting courtesy of our friends at Maindec.

< class='quote'>We had a query from a customer with regards whether FreeAXP can be run from within an Oracle VM environment. To prove this, we set up an Oracle VM configuration using two Intel servers running Oracle VM version 3, utilizing a remote iSCSI disk subsystem.

We configured a Windows 2008 VM, and installed FreeAXP running VMS version 7.3-1. We confirmed vMotion between the two Oracle VM servers, with virtually no noticeable delay in network activity at the point of transition. Additionally, the Oracle VM virtual network switches seem to have promiscuous mode enabled by default, unlike in VMWare, so the default network configuration supports DECNet.

FYI: Maindec has also confirmed VMware and vMotion support for FreeAXP and Avanti. Several customers have this in production.

Since VirtualBox is an Oracle product, what is the difference between Oracle VM and VirtualBox?

An internet search reveals that Oracle VM is short for Oracle VM Virtualbox.

This is the package that I have been using for an experimental VMS Cluster.

Virtualbox 3.1.8 worked well for clustering, but releases immediately after that would not allow the cluster traffic to pass. As soon as the cluster started to form the network interfaces would stop passing traffic until the VM was rebooted.

Virtualbox 4.1.8 showed some promise initially, but also started having problems with network traffic on the Windows VM only. One or both of the network interfaces would stop passing traffic. No problems were seen with the Ubuntu VM running SimH.

I have now been running Virtualbox 4.1.14 for a few days and so far the cluster running on a MacBook Pro has been stable for 5 days.

I've been reading your posts regarding VBox with interest, since I have Vbox running on my Ubuntu Linux laptop. I currently run WinXP as a guest.

How much of a performance hit do you see with Host OS---&gt;Windows---&gt;VMS? Is the performance reasonably fast enough to keep me "interested"? I have a PWS 433au that I would like to retire permanently, and run a virtual version of VMS on my laptop, but I wonder how responsive such a setup might be.

It has been on my TODO list to run the VUPs test on the cluster nodes and my real nodes.

I know the command procedure was posted somewhere in this forum, I just have not taken the time to track it down and run it.

It would be interesting somewhere to have a place like a WIKI page that a collection of VUPs runs could be posted so that people can compare how the different environments stack up.
