Hyper-V Fun…

August 14th, 2008 | No Comments | Posted in Microsoft, Virtualization

Or not. Managed to procure Windows Server 2008 w/ Hyper-V and a 120-day evaluation license yesterday. I promptly installed it on a Proliant DL380, went to install Hyper-V at which point it stated you must have Intel-VT enabled on this machine in order for Hyper-V to run. After much tabbing through pages of BIOS, i decided to give up on that server and use one of the other hundred available!

On the second machine, we enabled VT, installed Win Server 08, and then went to “add component > Hyper-V”, which also installed without error. On reboot of the server, it informed us that Hyper-V Virtual Machine Manager (VMM), aka The Important Bit, had failed to initialise, meaning we couldnt add any new VM’s, which is brilliant. When we tried to manually start the process, we recieved “Parameter Incorrect: Error 87″.

According to a colleague who has been on a Windows Server 2008 training course, this is caused by, nonsensically, the language being set to “non US”, i.e. not EN-US, during installation. I dont know WHY this should affect anything but apparently it does – i should have learned a long time ago that Microsoft and Logic dont go hand in hand. C’est la vie.

Hyper-V, thoughts by Tony Asaro, CSO of Virtual Iron

July 30th, 2008 | No Comments | Posted in Virtualization

Quite an interesting piece- i agree with his major points regarding the comparison beetween Hyper-V and ESX and that it cant be compared on an enterprise level due to the fact the products arent that similar, but i have to say that i think he is underestimating Hyper-V in the SME Market (small-medium enterprise), as small businesses wont be looking to implement ESX at $3000 a license, they will be looking to buy an OS for their domain controllers, file servers etc and if it comes with Hyper-V and its competitive pricing structure then i can see Microsoft starting to really dominate that market. Anyway, heres the article:-

Microsoft Hyper-V – Nothing and Everything Changes

http://blog.virtualiron.com/Virtual-Discourse/2008/07/microsoft_hyperv_nothing_and_e_1.html

We see the availability of Microsoft Hyper-V and System Center Virtual Machine Manager (SCVMM) as an important milestone in virtualization. But it really isn’t going to shift the market any time soon.

Everyone has been waiting for Microsoft to come into the market in order to bring true competition to VMware. However, this is not going to happen for some time to come. How long? It may never happen. Don’t get me wrong – Microsoft will challenge VMware on some level – but not in any real way for years – especially in large Enterprises. In that time VMware will continue to innovate, acquire new companies/products and increase their installed base.

There is speculation that Microsoft will dominate the SME virtualization market – the same that Virtual Iron is already selling successfully into. We know that Microsoft will do well in the SME but again it will be over time. There is a big market for Virtual Iron and that will be true for years to come. We’ve been shipping product since 2006 and have a proven track record and mature solution. Microsoft has a long way to go with their product. It isn’t just an issue of features (which they lack) but of implementing a virtual center platform that can manage the virtual infrastructure reliably. That is an extremely important point. This is the challenge for them and Microsoft is just at the threshold of this journey.

Therefore the reality is that everything and nothing changes with the coming of Microsoft Hyper-V and SCVMM.

Nothing changes because Microsoft doesn’t have a relevant product yet. Multiple industry analysts believe that Microsoft is 18 months with having a true server virtualization solution. In that time a lot will happen.

Everything changes because the Microsoft machine is rolling forward. And when a giant moves everyone pays attention.

As Microsoft educates the market with a rumored $300 Million in marketing funds dedicated to Hyper-V and SCVMM – and fail to deliver true server virtualization – Virtual Iron will leverage this opportunity to provide our proven solution. And while Microsoft stumbles through a 1.0 product and 2.0 and, and… Virtual Iron will continue to innovate and grow.

Lets Get Started: Para-Virtualization

July 29th, 2008 | 1 Comment | Posted in Microsoft, VMWare, Virtualization

First off, i’d like to just get the site kicked off with a brief +/- i wrote a few weeks ago on Para-virtualization.

+ Paravirtualization (PV) provides major security benefits, as the host server generally cannot access the virtual machines inside (if compromised) unlike Full Virtualization (FV). Also, virtual machines are totally black-boxed, and cannot see other VM’s on the same server.

+ PV provides an infrastructure with a lot more redundancy, backup and fail-over options than FV; using proprietary technologies such as “VMotion” (VMWare) which allow a virtual machine to be ran across 2 separate physical hosts in 2 separate locations.

- PV is expensive to run; as you will need hardware that is officially supported to run the hardware on (generally), compared to FV, such as VMWare Server, which you can install on any hardware running a supported Operating system such as Ubuntu, Win. XP, etc.

- Most common variant of Virtualization used in the Enterprise today.
- Examples include VMWare ESX/Vi3, XenSource aka Citrix.
- Uses a “Hypervisor” or Virtual Machine Monitor, to allow multiple OS to run on a host computer simultaneously. VMWare uses vmkernel as its Hypervisor.

Tomorrow -  Hypervisor types.
