From Ben’s blog : A while ago I blogged about how to allow non-administrators to control Hyper-V . You do this by editing the Hyper-V authorization store. What I failed to mention at that time was that this method does not work if you are...(read more)

Hyper-V Integration Services sobre Windows Server 2008 Server Core

tech-steps — Mon, 12 Oct 2009 05:00:00 GMT

El día de hoy instalé una máquina virtual Windows Server 2008 Server Core sobre Hyper-V v2 (Windows Server 2008 R2), al tratar de configurar la tarjeta de red resulta que no estaba instalada ninguna, esto se debe principalmente a que hace falta instalar los Integration Services de Hyper-V. Para hacer esto hagan lo siguiente:

- Clic en Action y seleccionen "Insert Integration Services Setup Disk"
- En el Command Prompt de Server Core accedan a la unidad virtual del CD
- Ingresen a la carpeta \support\x86 y ejecuten setup.exe
- Les pedirá que reinicien la máquina virtual y todo funcionará correctamente, espero les sirva.

! Four mistakes that can kill virtual machine performance

Petizme — Mon, 28 Sep 2009 05:00:00 GMT

Hi,

From SeachVirtualization site, see below:

1: Virtual machine screensavers
Screensavers are an absolute requirement for desktops in the hallways of our brick-and-mortar offices. They ensure that a user who walks away from his computer returns to one that has been secured against prying eyes. Screensavers can also provide protection in data centers. If screensavers on servers activate and lock the console after a few minutes of inactivity, they can protect that environment from an intruder who gains physical access.

But screensavers are a quiet consumer of processor resources. No matter how insignificant that screensaver seems, the processor power required to draw the pipes crawling across the screen or to scroll your favorite company slogan consume a percentage points of overall processor power. While that might not seem like much, consolidated virtual environments might have 10 or 15 virtual machines (VMs) running on a single virtual host. These percentage points add up when they are multiplied by the number of VMs. Even worse, if your environment uses hosted desktops through a virtual desktop implementation, this practice likely costs even more.

So turn them off. Remember that many environments enforce screensavers through group policies, which may mean an exclusion from existing group and corporate security policies.

2: Managing from the console
As with screensavers, this practice is a big no-no in virtualized environments because of the level of resources required to create and maintain an instance of the Explorer shell. Just logging into a virtual machine is hard on that VM's processor utilization. The process of creating a shell for the console can spike processor utilization during the login and logout process. Actually using any of the consoles on that server further consumes valuable resources. Logging in and accomplishing activity on your VMs' desktops increases the amount of memory they consume.

Microsoft provides the Remote Systems Administration Toolkit, PowerShell and VBScript, as well as many other tools for efficient virtual machine management. All these lightweight tools require much less VM capacity than a traditional login. So use them, and avoid wasting processing power and memory like an amateur.

3: Antivirus and anti-malware scanning of VM disk files
Your corporate security policy might not allow for the exclusion of Virtual Hard Disk or Virtual Machine Disk Format (VMDK) files from antivirus and anti-malware scans. But be aware that the real-time scans of such products can substantially reduce the overall performance of these files -- and, thus, their virtual machines. Since a VM's processing is highly dependent on its disk subsystem, any extra activities that slow down that process slow it down as well.

That's not to say that VM disk files shouldn't be subject to security scanning. Scheduled scans of such files can ensure that they don't get infected, without the processing overhead of real-time scans. Also, some of today's more advanced scanning products are beginning to incorporate virtualization awareness to reduce their overall impact. If your security policy will allow it -- or if you can bribe your security officer to look the other way -- definitely consider excluding these files from your real-time scans.

4: Windows Server's power options
At conferences around the country, I've encountered the final mistake repeatedly. The default power option of Windows Server 2008 upon installation is set to "Balanced." Of the three options available -- Balanced, Power Saver and High-Performance -- this is the second of the three in terms of overall system performance. You might save a few dollars on energy, but at the cost of wasting some of the server's processing power. Resetting the radio button to the high-performance option has a noticeable effect on how well VMs will perform.

[Hyper-V] Processor Affinity and why you don’t need it on Hyper-V

Hyper-V com 27 Sistemas Operacionais

CleberMarques — Sat, 19 Sep 2009 05:00:00 GMT

Estive durante algum tempo preparando diversas imagens de sistemas operacionais (em VHD) no Hyper-V do meu laboratório pessoal, entre as versões e tipos de SOs consegui reunir 27 deles, a idéia era apenas estruturar minha biblioteca de imagens, porém acabei transformando isso neste artigo também. Listo abaixo o nome e o tamanho do VHD, lembrando que estas instalações são “limpas” sem aplicativos e as últimas atualizações do Microsoft Updates (ou pacotes no caso de Linux). Acompanhem:

Nome do SO	Tamanho
Windows NT 4.0 Server Enterprise	733 MB
Windows NT 4.0 Workstation	740 MB
Windows 2000 Server com SP4	2.06 GB
Windows 2000 Datacenter Server com SP4	1.99 GB
Windows 2000 Advanced Server com SP4	2.06 GB
Windows 2000 Professional com SP4	1.77 GB
Windows Server 2003 R2 Enterprise com SP2 (x86)	1.66 GB
Windows Server 2003 R2 Enterprise com SP2 (x64)	2.27 GB
Windows XP Professional com SP3 (x86)	1.49 GB
Windows XP Professional com SP2 (x64)	4.22 GB
Windows Server 2008 Enterprise (x86)	5.55 GB
Windows Server 2008 Enterprise (x64 sem Hyper-V)	8.11 GB
Windows Server 2008 Enterprise (x64)	8.18 GB
Windows Server 2008 Enterprise (x64 Core)	2.30 GB
Windows Server 2008 Enterprise com SP2 (x86)	10.5 GB
Windows Server 2008 Enterprise com SP2 (x64)	15.0 GB
Windows Vista Enterprise com SP1 (x86)	5.65 GB
Windows Vista Enterprise com SP1 (x64)	11.8 GB
Windows Server 2008 Enterprise R2 (x64)	6.50 GB
Windows 7 Ultimate (x86)	4.74 GB
Windows 7 Ultimate (x64)	6.94 GB
Windows Home Server 2003 (x86)	2.56 GB
Windows Small Business Server 2008 (x64)	14.4 GB
Windows Storage Server 2008 (x64)	10.3 GB
Red Hat Enterprise Linux 5	4.55 GB
SUSE Linux Enterprise 10 (x86)	2.24 GB
OpenSUSE 11	3.78 GB

Lembrando que decidi não colocar na lista nenhuma outra versão do Windows Server 2003 que não fosse a Enterprise e R2, o Windows XP x64 não possui SP3 (por ser baseado no Windows Server 2003 x64 e este foi até o SP2 apenas). Enfim, o vencedor e tomador de espaço no HD foi o Windows Server 2008 com SP2 x64, com 15 GB J

Espero que a informação tenha sido útil.

Abraços.

HVRemote Updated

xperts64 — Sun, 09 Aug 2009 05:00:00 GMT

In case you missed it, John Howard has updated his HVRemote utility. This little gem, which keeps getting better and better, can completely configure both the client and the server to enable you to connect to a Hyper-V server from your Vista or Windows 7 desktop. You’ll still need some way to actually manage the server, and that could be the RSAT tools or the PSHyperV project on Codeplex. IAC, grab the new version of HVRemote. John has added even more intelligence and troubleshooting in this version.

Charlie.
