Improved Linux support on Server 2012 R2 HYPER-V

Microsoft is doing their best to welcome Linux as a first class citizen for their world and same goes on the virtualization arena. With the introduction of the Server 2012 R2 HYPER-V Microsoft has carried our several enhancement for the Linux support. This initially start with improving the LIS (Linux Integration Services) enhancements, thanks to the effort carried out by the MS team now LIS is integrated with several popular Linux distros.

Out the new improvements to the LIS two major ones that took my attention are,

Dynamic Memory support for Linux guest operating systems – with this we can treat Linux OS as a first class citizen in the HYPER-V. This is also welcome feature for virtual machine hosting providers as well. In my test lab I’ve installed Ubuntu 13.04 and configured dynamics memory. When the VM is in idle mode memory consumption has been reduced less than 200 MB!


Linux virtual machine backup support – Now you can use Windows Backup to backup the Linux VM while they’re running (although slight pause happens during snapshot) But this is a welcome feature I would see with significant value.

Live virtual machine cloning – Windows Server 2012 R2 HYPER-V

Server 2012 R2 will be official launch is 4 days ahead. Lot of new features introduced in the Server 2012 R2 and System Center 2012 R2. I’m really interested about the HYPER-V side of the improvements introduce by Microsoft. It’s like listening to your demands and providing you solutions 🙂

The One I’m about to talk to you about is such scenario. You can clone virtual machine’s and virtual machine’s snapshots while the virtual machine is running! This feature really comes handy when you want to do some testing on the running virtual machine without disturbing to anyone.

You simply take a clone copy of the running VM and do patching, application upgrade and test and verify. Once that completed you can safely apply those changes to the production VM knowing things will go smoothly 🙂

Think about it. This is kind of a dream for System administrators,Application managing engineers. You get a exact copy of production system running in isolated environment and do the testing for verification. To put more into your brain, we can also take a clone of the virtual machine “Snapshot” and run it in isolated environment, how cool is that.

So go ahead and grab a trail copy of Server 2012 R2 HYPER-V and get’s your hands dirty.
