You’ll want to read Isaac’s blog post about the RC milestone of Windows Server 2008 R2. His post focuses on 64 LP support and processor compatibility mode for live migration. Read the post here.
Here’s an excerpt:
We have seen processors grow from 1, 2, 4, and now 6 cores on a single processor, soon to hit 8. Within the Windows Server 2008 R2 lifecycle, 64 logical processor servers will become commonplace (8 processors x 8 cores). Virtualization is the natural fit for these next-gen servers, allowing them to consolidate a greater number of virtual machines on a single host. Hyper-V is in line with these hardware trends all with an eye towards bringing you greater VM density. The dev team has done a fantastic job in building and testing a platform that can scale.
Let’s take a quick look at the history of logical processor support for Hyper-V:
- Server 2008 Hyper-V 16 LP Support
- Server 2008 Hyper-V +update (KB95670) 24 LP Support
- Server 2008 R2 Hyper-V Original POR 32 LP Support
- Server 2008 R2 Hyper-V RC/RTM 64 LP Support!
Processor Compatibility Mode for Live Migration
Live Migration is the killer-feature in Windows Server 2008 R2! Previous to the RC build of Windows Server 2008 R2, identical CPUs were needed across every node in the cluster in order to perform a live migration. As we came closer to the RC milestone we got feedback from customers and partners asking, "What if I deploy additional nodes that contain newer processors with features not contained in the original nodes?" Well, we’ve solved that problem due to tremendous effort by the Hyper-V development team.
Processor compatibility mode is very straightforward. It enables live migration across different CPU versions within the same processor family (i.e. Intel-to-Intel and AMD-to-AMD). However, it does NOT enable cross platform from Intel to AMD or vice versa. It works by abstracting the VM down to the lowest common denominator, in terms of instruction sets, which enables live migrations across a broader range of Hyper-V host hardware.
There are a few things to note: Processor compatibility mode is disabled by default but you can configure it on a per-VM basis. There are no specific hardware requirements other than the CPUs must support hardware assisted virtualization (i.e. Intel’s IVT and AMD’s AMD-V).
“Still on the Windows 7 Beta,? You need to move to the RC and fast. Starting July 1st, the Beta will start to reboot every 2 hrs and expire Aug 1st.
Want to download the RC? . The RC download program closes August 15th. After that, you won’t be able to get the download, but you can still install the RC and get a key if you need one. (To get a key, just go to the Downloads page and follow the instructions.)
If you’re using the Windows 7 Release Candidate, we hope you like what you see. Let us know — go to http://input.microsoft.com and tell us what you think. You’ll be able to give feedback on various aspects of the operating system

This truly is an exciting day for me personally as MCT to anounce that the MCT Virtual Summit is ready, running and it’s great
Microsoft is starting the Opening session for the MCT Virtual Summit today 18/06 at 12pm Sydney Time.
Microsoft are going to presenting in a total of 6 languagues, English, Spanish, Portuguese, Chinese, French and German.
Having sessions with many deep technology subjects on Microsoft Windows 7, Microsoft Server 2008, Microsoft Exchange 2010 and Microsoft Office Communication Server 2007. Technology dive into Visual Studio Team Systems 2010. First Look at Microsoft Office 2010.
This is some pretty amazing content presented by outstanding speakers and there is still time to register. Go to www.MCTSummit2009.com and you can register for the event today.
In addition to all the new capabilities R2 Beta introduced here’s what is new in SCVMM 2008 R2 Release Candidate:
Enables migration of storage for a running VM. This is especially relevant as customers upgrade to Windows 2008 R2 as it allows them to easily migrate away from their existing one VM per LUN deployments and consolidate their VMs into a single CSV. For Hyper-V, this feature enables migration of a running VM?s storage both within the same host and across hosts with minimum downtime. For VMWare, this feature enables storage vMotion.
Rapid VM Provisioning:
Enables rapid creation of VMs without the need to copy VHDs over the network. Customers can now use storage technologies such as snap cloning to clone VHDs and then use the rapid provisioning feature to create VMs while continuing to take advantage of the VMM features to do OS customization and IC installation.
Host compatibility checks:
Enables checks for CPU features and enlightenment parity to ensure compatibility between a VM and a host prior to migration. A related feature to make a VM compatible with a host by limiting the use of certain CPU features is also enabled.
Queuing of Live migrations:
Enables users to do multiple live migrations within a cluster. VMM now detects the condition where live migrations fail due to collisions with in-progress live migrations and automatically performs queuing and retries in the background.
Support for 3rd party CFS:
Enables support for clustered file systems from ISVs that implement functionally similar to CSV (Clustered shared volumes). This feature allows for backwards support for CSV scenarios on Windows 2008.
Support for Custom Disk resource:
Enables support for Veritas volume manager by recognizing Veritas volume manager disks as a cluster disk resources.

The Tech•Ed 2009 season kicks off next week in LA, and the show comes to Australia and New Zealand in mid-September. We’ve just opened the Call for Content tool so now’s the time to submit that great idea for a session. Details about how to submit are at the bottom of this post.
Here are the rules for submitting content and what we’ll cover/not cover if the track owners select your session(s).
All the way through the process you’ll be able to review your submission and track its status. This is the first time we’ve opened up the Call for Content publically like this and we’re likely to receive many more proposals than we’ve got slots to fill, so please don’t be disappointed if your submission isn’t selected.
Tips for Successful Submissions
- Write a descriptive, fun and enticing title
- Target 300-400 level technical content; 200 level content is in low demand
- Describe content that is new, unique or significantly refreshed from a previous presentation.
- Take a solution oriented approach
- Align your topic to the technologies listed for the track
- Ensure there is no marketing in your content
- Showcase your speaking experience
- Focus on currently released technologies, technologies in beta or technologies that will be released within 12 months of Tech·Ed
- Include one or more live demos. Historically, sessions with strong demos receive higher audience scores
Submitting a topic
So how do you go about submitting a session? Go to the Call for Content tool and register with your email address and the RSVP code TechEdANZ. Fill in all the details and hit submit. You can come back to the site at any time to update or review the progress of your submission.
