Running CentOS 7 on a gen2 VM in Hyper-V

June 27th, 2014 No comments

In my latest blog I was exploring the possibility to get a Redhat Linux to work in a generation 2 VM and I was also explaining that I had some issues with the CentOS version 7 that is currently being developed and that issue was with the EFI boot and it was malfunctioning!

Now as of yesterday 25 of June when there was a new release I could actually get a working CentOS 7 in a generation 2 VM on my lab environment!

So to get the fresh build installed on a Gen2 HyperV 2012 R2 VM you can do the following,

here I found the Boot ISO -> http://buildlogs.centos.org/centos/7/os/x86_64-latest/images/ and downloaded the boot.iso and configured it to be used for boot in my test-VM and as I described in the other post I unchecked the Secure boot also

Once booted I connected the network and then added the path to the repository

Screen Shot 2014-06-17 at 22.30.29

The path to be added was http://buildlogs.centos.org/centos/7/os/x86_64-latest/ , by using -latest in the path you will get the latest build instead of some old maybe not so well working version, as described on their page the distribution is still being developed

And then choosing what roles to install and partitioning of the disk and then start the installation :-)

Once installed you can see that it now nicely boots into CentOS and I can log in

And you can see that it utilizes the Dynamic Memory function of Hyper-V also

Running Redhat Enterprise Linux 7 in a generation 2 VM on Hyper-V

June 18th, 2014 No comments

I was reading the post from Ben Armstrong how he installed and configured a Ubuntu Linux VM to work under a generation 2 VM.

And after that I wanted to try this with either Red Hat Enterprise Linux 7 or CentOS 7 as they would incorporate the Linux integration components that would be needed for being able to let go of that VM BIOS legacy generation 1 Hyper-V VM :-). Red Hat has released their 7 but CentOS is still in buildmode and thus this would be done on their “nightly build” as described on the site http://seven.centos.org and I did take a test with the current release but got an error during install with the EFI Boot so I went for the Red Hat and tried with that.

So Downloading the Redhat ISO and creating a VM was the first steps, If you do not have an account at redhat you can sign up and download a trial.

And then I created a VM and as Ben showed I disabled secure boot and added the ISO to boot:

After that I booted the VM and connected the network and configured the settings and choosed a Server with A GUI

Screen Shot 2014-06-18 at 14.45.22

The installation was successful and I could reboot with no warnings or errors

Screen Shot 2014-06-18 at 15.00.08

Then once the installation was complete I could start a browser and test and as you can see it is a Generation 2 :-)

Screen Shot 2014-06-18 at 15.10.27

I will during the next couple of days check out the new builds of CentOS and see if my error will be fixed and I can create a Gen2 VM of that one also :-)

Adding more external IP´s to your WAP NVGRE VM´s

June 3rd, 2014 No comments

So I have been during these two last days been in deep waters to find out a customers demands and the possibility to add more than one external IP to the same NVGRE enabled VM network within WAP and VMM and the Hyper-V Network Virtualization Gateway this as the ports from the external application the customer has cannot be altered and they need to access several different VM´s simultaneously.

Described in this visio diagram the customer wish is:

Drawing1

 

As you maybe know, within the VMM when you have configured the HNV there is no possibility to add more external addresses in the GUI and configure port forwarding.

networknatvmm

So how to do this then, well there is a way and that is called PowerShell on the HNV Gateway and first you add the external address and then add the NAT rules

Here is a screendump of an addition of a port rule:

newnetnatbinding

To get the NatName I added the first external IP and Port rules through VMM and then I could use that information when creating the rest config from within the HNV gateway.

The following cmdlets are available on the HNV GW

Observe though that when adding these things directly in the HNV GW you cannot manage these rules and IP addresses in Windows Azure Pack portal or VMM!

New version of the Microsoft Virtual Machine Converter 2.0 and MAT

April 8th, 2014 No comments

Today Microsoft released the long awaited new version of the Virtual Machine Converter (the 1.0 version could be integrated with MAT but had limits in both VMware and Hyper-V latest releases). Microsoft has also released a new version of the MAT (migration automation toolkit) that supports the MVMC 2.0 to automate the migration!

New Features in MVMC 2.0

MVMC 2.0 release of MVMC includes the following new features:

    • Converts virtual disks that are attached to a VMware virtual machine to virtual hard disks (VHDs) that can be uploaded to Windows Azure.
    • Provides native Windows PowerShell capability that enables scripting and integration into IT automation workflows.
      Note The command-line interface (CLI) in MVMC 1.0 has been replaced by Windows PowerShell in MVMC 2.0.
    • Supports conversion and provisioning of Linux-based guest operating systems from VMware hosts to Hyper-V hosts.
    • Supports conversion of offline virtual machines.
    • Supports the new virtual hard disk format (VHDX) when converting and provisioning in Hyper-V in Windows Server® 2012 R2 and Windows Server 2012.
    • Supports conversion of virtual machines from VMware vSphere 5.5, VMware vSphere 5.1, and VMware vSphere 4.1 hosts Hyper-V virtual machines.
    • Supports Windows Server® 2012 R2, Windows Server® 2012, and Windows® 8 as guest operating systems that you can select for conversion

in the link you can read more about the MVMC functionality

As you can see in the wizard the option to upload the converted VM to Azure directly has been added

And now in this version we have native PowerShell with the MVMC PS module as described above:

Screen Shot 2014-04-08 at 20.05.11

I will show more in a later post how it can be used and how it works with both migrations to Hyper-V and also directly to Azure :-)

both MVMC and MAT can be read about and downloaded here

Automated PowerShell to keep your template vhd(x) IC updated

March 31st, 2014 No comments

For the Veeam Seminar I did some digging in how to check and also apply updated integrational components on virtual disks in the System Center VMM library and found Ben´s script which I altered to fit my goal. This is quite convenient based on that you can schedule it and always have updated IC´s on those VHDX in the library.

I check and get the current IC´s from one Hyper-V host and thus based on that if it has been updated I also get that update instead of using a copied IC version locally in the VMM server. The script runs on the VMM server and that is why I use the Mount-DiskImage cmdlet instead of the Mount-VHD as that does not work on a non-hyper-V enabled windows server.

Recordings and code from SMA and Powershell webinar with Veeam

March 29th, 2014 No comments

Last week I had two webinars together with Veeam in the subject of “Automating daunting virtualization tasks”. Now these have been uploaded and shared on Veeams web. One is in swedish and one in english. during the webinar I show some different tasks that can be managed and handled with the Service Management Automation (SMA) and utilizing PowerShell.

51075482-98cb-11e3-82f1-12313b12ccaf-large

here is the english version: http://www.veeam.com/videos/webinar-replay-service-management-automation-akerlund-en-3932.html

and here is the swedish version: http://www.veeam.com/videos/webinar-replay-service-management-automation-akerlund-sw-3649.html

Here are some of the tasks and the PowerShell code,

First one of the tasks was adding VM´s to cluster where I utilize the function in this link

Next task that can be automated that you always will have a percentage free on the C drive for the VM´s (it both shrinks and expands), I am utilizing the generation 2 VM´s so for this to work your VM´s have to be configured with this latest virtual hardware version on Hyper-V 2012 R2

As you can see when I extend the size I make the VHDx about 230 MB larger to be able to set the partition to the size calculated regarding the overhead of the virtual disk, so if I would have tried to make both the VHDx and partition 15GB it would fail..

The rest of the scripts will be uploaded later in a follow up post. Of course there can be improvements in the ways to do things and if you have any comments or ideas please share :-)

 

Updated Raiders of the lost Cluster VM´s PowerShell function

March 17th, 2014 No comments

In 2012 I did a blogpost about a PowerShell function to find VM´s on Hyper-V Cluster nodes that was not configured as cluster resources and thus not being Highly Available in case of a hardware failure or maintenance work on the Hyper-V hosts…

687883034_1836208864001_raiders-of-the-lost-ark-imax-trailer-still

I have today made an update to the function so that it only gives the VM´s that have either SMB or CSV storage and not if you for some reason have VM´s residing on local storage within your clusternodes which can be the case for domain controllers or other appliances etc..

Good luck in your raid for the Lost Ark ;-)

Automate daunting virtualization tasks  with SMA

Now that you have set up your virtualization environment, you’ll want to automate it. In this webinar, you will learn how to do this with Service Management Automation(SMA) and how to integrate automated tasks into the Hyper-V virtualization environment. You will use different runbooks to automate some boring but necessary tasks that IT admins have to do.

This webinar will show you how to:

  • Automate patching of virtualization hosts
  • Expand virtual hard disks based on usage
  • Automatically update integrational components on VMs
  • Automatically update virtual hard disk templates
  • Clean old snapshots that have been forgotten
  • And more…

If you want to register and be part of this crazy one hour with the Swedish Chef you can do it on the following link

And guess what, It comes in a swedish version also! Check out in the following link and if you understand Swedish, register here!

Windows Server 2012 R2 SOFS with tiering require some disks..

March 2nd, 2014 No comments

I was at a meeting last friday and they where in the process of deploying a Scale Out File Server environment on Windows Server 2012 R2 and that with a Dell jbod box.

MD1220_2

One important thing to consider when designing this is that if you want to use all the features in the new 2012 R2 with storage spaces there are some limits that could imply and affect your design.

If you want the new cool performance intelligent storage tiering in 2012 R2 that can only be used with either simple or mirroring protection on the physical level which result in quite an overhead on disks in your jbods to get some TB for the actual data. If only the deduplication feature would have been supported with server workloads and not just VDI setups, then this would not have been such a big deal.

Screen Shot 2014-03-02 at 08.52.51

Setting up your environment based on this would require some planning and creating several different storage selections where not everything stored on your superperformance auto-tiering parts of your SOFS. Maybe your budget would allow you to fill the JBOD with only SSD´s and then this is no problem :-) but if not you should at least consider creating several different shares where the virtual disks either have storage tiering with mirroring or a plain disk with parity.

I would love to see some development in the SOFS storage integrated with Hyper-V in the same manner that VMware has with their Storage-DRS that could, based on different workloads and their load on different VHDX, be moved between the different datastores not just the tiers. This could be even more refined when adding a StorSimple box and the data that has not been accessed for a while would be offloaded to Azure.

stokage-cloud-StorSimple-Microsoft

Yes I know the StorSimple hardware needs a refresh in their NIC connectivity (in the current boxes there is a 2*1 Gbit active) but hopefully we will see some new hardware in a not to far future. And in an solution where the StorSimple box would be used and connected in a SOFS cluster together with JBOD´s the network bandwidth would not have such a large impact.
