The FREE MVP Community Camp (ComCamp) is a six-day event with both Live Webcasts and In-Person Seminars. MVPs from nine countries will deliver webcasts available to anyone anywhere to learn trends and techniques from these industry leaders; the in-person seminars will be available in 22 cities across seven countries with tracks providing opportunities to connect with others in the same expertise/interest area and to have a number of technology hands-on experiences.

Delivered by MVPs who not only possess the expert knowledge in their field but also have been influential technical leaders to IT community and audiences. Each session is 60 minutes long and includes Q&A to help you get an instant feedback on questions you have had during the session.  Between each session, 15 minutes break is given for MVPs and community members to network, share their thoughts on topics presented and share technical experiences.

There are sessions happening in the principal cities of Australia : Sydney, Brisbane, Melbourne, Perth and Adelaide and New Zealand. Make sure you register early to secure your spot.

Countdown for XP End Of Support started. Where do I start?

April 10, 2013 Leave a comment

Microsoft will end Extended Support on April 8, 2014: no new updates will be released after this date.

If your organization has not started the migration to a modern desktop, you are late. Based on historical customer deployment data, the average enterprise deployment can take 18 to 32 months from business case through full deployment. To ensure you remain on supported versions of Windows and Office, you should begin your planning and application testing immediately to ensure you deploy before end of support.

After April 8, 2014, there will be no new security updates, non-security hotfixes, free or paid assisted support options or online technical content updates. Running Windows XP/SP1/SP2 or even SP3 and Office 2003 in your environment after their end of support date may expose your company to potential risks, such as:

  • Security & Compliance Risks: Unsupported and unpatched environments are vulnerable to security risks. This may result in an officially recognized control failure by an internal or external audit body, leading to suspension of certifications, and/or public notification of the organization’s inability to maintain its systems and customer information.
  • Lack of Independent Software Vendor (ISV) & Hardware Manufacturers support: Back in 2011, many independent software vendors (ISVs) were already unlikely to support new versions of applications on Windows XP.

Where do I start?

There is no upgrade path. You will need to do a clean install. This means you will need to migrate the users’ data and reinstall or repackage all their applications for the new OS. This will take some time to test all of the hardware, peripherals and applications to ensure they will work with Windows 7 or Windows 8.

Visit The Springboard Series on TechNet to learn how to Explore, Plan, Deliver, Operate and Support Windows 7 and 8 in your environment.

Windows 2012 Hyper-V RTM to be released first week of August 2012

July 10, 2012 Leave a comment

Microsoft announced at WPC in Toronto, both server and client announced RTM (first week of August) and GA(Sept for Server, Oct for client) timing publicly:

“Windows 8/Windows 2012 is on track to Release to Manufacturing (RTM) the first week of August. For enterprise customers with Software Assurance benefits, they will have full access to Windows 8 bits as early as August. Additionally, she noted that RTM is when we’ll be turning on the commerce platform so that developers can start earning money for their apps ”

SYSRET 64-bit OS privilege vulnerability on Intel, DOES NOT AFFECT HYPER-V

June 18, 2012 1 comment

 

Last week US-CERT warned of guest-to-host VM escape vulnerability and it was reported that an issue on Intel based servers could lead to a “break out” from a VM to the host in certain virtualisation products, including Microsoft : “A ring3 attacker may be able to specifically craft a stack frame to be executed by ring0 (kernel) after a general protection exception (#GP). The fault will be handled before the stack switch, which means the exception handler will be run at ring0 with an attacker’s chosen RSP causing a privilege escalation” : http://www.kb.cert.org/vuls/id/649219
Affected vendors include Intel Corp., FreeBSD, Microsoft, NetBSD, Oracle, RedHat, SUSE Linux and Xen.

But Hyper-V is NOT Affected By VU#649219 VM “Break Out”.

I’ve asked the Microsoft Hyper-V product team Redmond if Hyper-V was actually affected and as per their answer:

•The problem does affect the 64-bit OS’s on Intel hardware, but Hyper-V is not affected.

•This problem will not lead to break outs from Hyper-V VMs.

•Windows 8  is not affected

•Windows Server 2012 is not affected.

Windows Server 2012: Hyper-V Network Virtualization

April 24, 2012 2 comments

Hyper-V Network Virtualization allow customers to keep their own internal IP addresses when moving to the cloud while providing isolation from other customers’ VMs – even if those VMs happen to use the exact same IP addresses.

The way it works is that each VM receive two IP addresses :

The first one, the IP address visible in the VM, is relevant in the context of a given tenant’s virtual subnet. Following the IEEE nomenclature we call this the Customer Address (CA).

The other IP address is relevant in the context of the physical network in the cloud datacenter. This is called the Provider Address (PA).  This decoupling of tenant and datacenter IP addresses provides many benefits.
One of the benefits is that you can move your VMs to the cloud without modifying the VM’s network configuration and without worrying about what else (or who else) is sitting in that datacentre.

Another big reason is the policy enforcement in the end hosts that provides a scalable solution for multi-tenant isolation, instead of using Vlan’s, for isolation.

There are 2 different mechanisms to virtualize the IP address:

Generic Routing Encapsulation (GRE) : should be used for network virtualization, because it provides the most flexibility and performance. It will be used for most environments/deployments

IP Rewrite : may be appropriate to provide performance and compatibility in some current high-capacity datacenters.

 

A very good article was posted by Jeffrey about this topic

Windows 8 : Why should my hardware have SR-IOV capabality ?

April 4, 2012 1 comment

Single Root I/O Virtualization (SR-IOV)

SR-IOV capability will significantly reduce the overhead on network IO operations.

It allows for a virtual machine to have near native IO against the physical NIC, allowing applications that require very low latency to work inside of virtual machines.

What does it require?

  • It must bypass teaming
  • Interrupt and DMA remapping
  • Access Control Services (ACS) on PCIe root ports
  • Alternative Routing ID Interpretation (ARI)
  • Hardware virtualization, EPT or NPT

Where to create:

– In the Hyper-V Manager, click on Virtual Switch Manager on the right panel

– Click Add New Virtual Switch

– Type the name of the virtual switch

– Tick box for Enable Single Root I/O virtualization (SR-IOV)

IMPORTANT :

More about SR-IOV here : SR-IOV feature (Single Root – I/O Virtualization)

Microsoft SR-IOV Support on Dell PowerEdge Servers (source : http://en.community.dell.com/techcenter/os-applications/w/wiki/3459.dell-supported-platforms-for-windows-server-8-sr-iov-feature.aspx):

Dell PowerEdge 12th Generation servers support the SR-IOV servers but previous generations have exceptions.

Below is a list of Dell 11th Generation platforms that support the SR-IOV feature:

  • R910

The following platforms are also supported and must be an 11G Generation II server:

  • T410, R410, R510, R610, T610, R710, T710.

How to identify an 11G Generation II system:

  1. These servers will be physically marked with symbol “II” on the Express service tag.  The Express service tag is located in front panel of the system.
  2. These systems support Intel 56XX (Westmere) processors
  3. The System Revision Field in the iDRAC GUI will have “II”

Supported SR-IOV network cards:

  • Intel X520 10GB Ethernet adapters.

Because Windows Server 8 Beta is a pre-release product still in active development, Dell does not provide any support for this pre-release software and it is not recommended for use in a production environment.
