virtual machines will replace dual booting ????

When your soft ware application can not performance or install on your OS( such as Windows xp Pro x64 or Windows 7 or some other new and unfamiliar operating sysem ),may you’ll consider dual booting.Of course ,this is not a bad choice.
Yes ,you can have dual operating systems,but you can’t run both at once.you must shut down everyting you are doing .Start  the slow, annoying ,painful process to reboot into the second OS.  Much more  to your  annoyance,you had to re-install all applications .Some day,you find one of two operating systems useless or you want to install a new or better functional Operating System.So,you want to remove that from your C:drive and you are afraid that it will cause nuisance to your computer or the operating system.
Maybe ,you will step back!!!

If you use the virtual machines ,maybe everything will go easy!!

For example ,your OS is Windows xp 16-bit version or 32 bit -version,you can
run the Windows XP Professional x64 Edition  into a virtual machine .So,you can run one of them you  need ,without shutting down any work you are doing.You can choose the operating system to run your application.

the favorite is running a virtual machine on your computer is essentially the same as running a full second computer.

But for more normal workloads, I find the performance quite acceptable .
But ,the VM can’t answer all things.
The Virtual machine does not support FireWire and USB 2.0 while you need to have USB support in your VM enviornment.Also,A  VM  will have an influence on your guest and host machines.Obiviously,if you guest machine are running a game ,your host machine can’t perform well.

Maybe ,both  of the VM and dual booting  have their advantages .
Maybe,We can share your better ideas.

Microsoft learning: analysis for Exam 70-652

Filed under: Server technologies — Tags: , — Luna @ 5:21 am

Audience profile
Candidates for this exam typically have more than one and a half years of experience working in Windows Server 2003 and/or Windows 2008 Server environments as system administrators. Additionally, the target audience is familiar with virtualization products and technologies.
Here is some emphasis of the exam:
1. Installing Hyper-V (14 percent)
2. Configuring and Optimizing Hyper-V (20 percent)
3. Deploy virtual machine (30 percent)
4. Managing and Monitoring Virtual Machines (36 percent)
Let us from the above emphasis to give you a few examples.
1. You evaluate the purchase of a new server for the network.
A hardware supplier recommends a server that has the following hardware configuration:
Dual-core 32-bit processor
4 GB of RAM
One single-port network card
Two SATA hard disks
You need to change the hardware configuration to ensure that you can install the Hyper-V server role. Which hardware component should you replace?
A: hard disks
B: memory
C: network card
D: processor
Correct Answers: D

This example is about the configuration of hyper-v. If you want to get more information see the web site (http://www.microsoftbible.com/the-configuration-of-hyper-v.html ). To install and use the Hyper-V role, you will need the following: An x64-based processor. Hyper-V is available in x64-based versions of Windows Server 2008—specifically, the x64-based versions of Windows Server 2008 Standard, Windows Server 2008 Enterprise, and Windows Server 2008 Datacenter. Hardware- assisted virtualization.
2. You manage a server that runs Windows Server 2008. The server has the Hyper-V server role installed.
The server hosts three virtual machines named VM1, VM2, and VM3. Integration Services have been installed on all virtual machines.
You need to ensure that VM1 starts before VM2 and VM3 when you restart the Hyper-V server.
Which settings should you modify?

A: automatic Start action
B: automatic Stop action
C: Hyper-V Settings
D: Integration Services
Correct Answers: A
Explanation:

This example is about Managing and Monitoring Virtual Machines,There are many questions are similar to the type of this example. For instance:Monitor and optimize virtual machines. Tool: SCVMM, processor, optimize memory, network, disks. Manage virtual machine settings: DVD/ISO, NIC, Integration Services, state of virtual machines.
Dealing with these problems: you need to familiar with virtualization products and technologies. In this question, To make sure VM1 starts before VM2 and VM3 , you need modify the Automatic Start Action ,it defines what action should be taken with regard to the virtual machine when the host system boots. Options include not starting the virtual machine, starting the virtual machine or only starting the virtual machine if it was running when the host last shut down. The option is also provided to delay the start up by a specified number of seconds. This avoids all virtual machines starting at the same time and allows critical virtual machines to start before less critical ones.

On the basis of the above, there is something you need to notice in this exam
1. Create or clone a virtual machine: differencing disks, copying Virtual Hard Drive (VHD), SCVMM vNext, PXE Boot (legacy network adapter).
2. Create a virtual disk: pass-through disks, fixed versus dynamic, differencing disks, IDE versus SCSI, Virtual Hard Disk Wizard
3. You should know the difference between internal virtual network and the external virtual network.
4.Some commands in virtual machine need to know:ocsetup Microsoft-Hyper-V command,oclist | findstr /i Microsoft-Hyper-V command,Sysprep /quiet /generalize /oobe /shutdown command.
5. Manage snapshots and backups:snapshots,backup within a virtual machine
