Know to Configuration of Windows 8 Virtual Machine Step By Step guide

Know to Configuration of Windows 8 Virtual Machine Step By Step guide



Configuring a Windows 8 Virtual Machine

With the launch of Windows 8s Consumer Preview, youre probably itching to spend some quality time with Microsofts latest operating system. Although you may have already downloaded the ISO, we bet some of you havent decided how youre going to install it.
Considering youve just met, we assume most of you arent ready to clear a dresser drawer for Windows 8. Overwriting your current stable OS with pre-release code could be a recipe for disaster, though at least one TechSpot staffer is taking the plunge.
Dual booting is popular, but in our experience, rebooting into a separate environment is more trouble than its worth when youre just trying to sample beta (err, "preview") software. The same could be said for using the OS on a secondary PC near your primary rig.
Windows 8 Virtual Machine
Fortunately, running Windows 8 in a virtual machine solves all that: it wont remove your current OS, you can access it anytime you want without rebooting and it doesnt require any extra hardware. Whats more, the test OS can be deleted in only a few mouse clicks.
This write-up wont have much to offer folks experienced with virtual machines, but many users are still intimidated by them. We hope to demystify the process with a guide that installs a fully functional, commitment-free copy of Windows 8 inside your main OS.
So, what do I need?
Not much! You probably want 1-2GB of RAM and 20-30GB of storage allocated to the Windows 8 VM. You need a processor that supports virtualization (basically any major chip from Intel or AMD released since 2006). In other words, you need a semi-modern PC.
Accompanying said hardware, you need to download a copy of Windows 8 (either 32-bit or 64-bit will work fine, but the former calls for half the RAM and 4GB less storage). You also need virtualization software. Were using VirtualBox, a free solution from Oracle.
Got it. Lets do this!
Honestly, by the time youre done, youll probably wonder why you even consulted a walkthrough. Configuring a basic virtual machine is a lot easier than it might seem if youve never done it. Start by clicking New in VirtualBox and click Next on the first prompt.
Youll be asked to name your virtual machine. The name is purely for identification purposes, so you know exactly what the machine is later on. Were using Windows 8 CP 64-bit. You also have to choose the OS youre installing (hint: Windows 8 or Windows 8 64-bit).
Windows 8 Virtual Machine
The following screen will ask you to set a RAM size. As a minimum, Microsoft recommends 1GB for the 32-bit version and 2GB for 64-bit. Were heeding that advice, but if you want to try scraping by with less, you can always reallocate more memory to the VM later.
Assuming this is your first VM youll have to choose "Create new hard disk" on the following screen. In doing so, youll be asked to pick a format. You can leave VDI (VirtualBoxs own format) selected unless you want to run the VM with other virtualization software.
Windows 8 Virtual Machine
Unless you have a specific need for defining a fixed size virtual disk - unlikely if youre reading this guide - youre fine with a dynamically allocated disk. This will expand your virtual disk as the virtual machine needs additional space instead of starting at the larger size.
By default, the virtual disk will be created in C:UsersUSERNAMEVirtualBox VMs. If your C: drive is short on space or if you simply want the VM stored elsewhere, you can set it now. My C: drive is an 80GB SSD, so Im creating the virtual disk on a secondary HDD.
Windows 8 Virtual Machine
It cant hurt to glance over the settings summary before you proceed, but seemingly anything can be changed later. If youre satisfied, click Create. Assuming you werent met with any errors, you just created a virtual machine -- albeit one without an operating system.
Wait. What about Windows 8?
Youre only moments away from installing Windows 8. Right click your new VM and open Settings. In the left column, click Storage > Empty (under IDE Controller) > the CD/DVD icon (under Attributes) > Virtual CD/DVD disk file and navigate to the Windows 8 ISO.
Windows 8 Virtual Machine
Windows 8 Virtual Machine
Once you see the Windows 8 ISO attached under the IDE Controller, click OK to exit Settings. Now you should be able to launch your virtual machine and begin a standard Windows installation. If youre familiar with that, you shouldnt need this guide any further.
Youll be prompted to set your language, time and currency format, and input method. Youll also have to supply a product key (DNJXJ-7XBW8-2378T-X22TX-BKG7J). Agree to the terms, choose a Custom setup and install Windows 8 to the only unallocated space.
Windows 8 Virtual Machine
The installation took about 20 minutes on my system. Youll eventually be asked to choose an interface color, a PC name and other such customizations. After playing a round of Twenty Questions, setup should complete and youll see the Windows 8 desktop.
Son of a... this wont work!
Windows 8 Virtual Machine
If you meet the minimum system requirements, you shouldnt encounter any issues. Its worth noting that while your processor might support virtualization, the feature could be disabled in your system BIOS. Feel free to seek help in the comments
Windows 8 Virtual Machine
I havent had any performance issues running Windows 8 with a single CPU core, but you can dedicate more cores in the VM settings window (System > Processor). Likewise, you can allocate more VRAM, tweak the network adapter and configure shared folders.

Know to use NSLOOKUP for DNS Server diagnosis

Know to use NSLOOKUP for DNS Server diagnosis


The DNS protocol has been around for decades and is a stable and reliable protocol.Even so, DNS does occasionally have problems. PING is a great tool for DNS serverdiagnosis, and I tend to use it quite frequently myself. However, sometimes PING justdoesn’t give you enough information about the problem at hand. When you need moreinformation about a DNS problem than what PING provides you with, you can alwaysturn to the NSLOOKUP command. In this article, I will show you how to useNSLOOKUP

Everything You Need to Know about Hybrid Drives

Everything You Need to Know about Hybrid Drives


We live in the world where our digital stuff gets compact but their capabilities seems improved over a time as well as several advancements were made to make it superior in performance, have high usability and acceptance rate, deliver best value for money etc. Same case were applies to our conventional hard drives which now comes in variety of higher storage capacity and sizes which gets reduced to its lowest, merely 2.5 or 3.5 Inch for Ultrabook or tablet PCs. Many other improvements were made to deliver higher performance rate, reduced time for starting PC or opening applications etc.

One major change took place that is instead of using platter for storing your digital information, many modern drives (commonly known as solid state drives and hybrid hard drives) uses flash chip based storing area, that reduces duration to copy or move data, boot Windows or initialize heavy applications/games.

This all becomes possible only after creating the caching algorithm (an inbuilt mechanism comes in devices firmware) which generally stores information about recently used applications, boot history and registry details. So, the system wont need to look for those specific details and instead, they only initialize the caching files and fetch all the details which the system requires to boot and start Windows as well as immediately start all the startup applications. As results, you can boot system and initialize applications faster.

However, because of using flash chips and modern firmware, solid state drives costs were so high that it hardly meets the budget of normal home PC user such as normal 128 GB SSD costs you around $135 or so, whereas a 2 TB of traditional hard drive would be purchased in the same cost. So if youre a computer warrior and needs high storage capacity wishes to have high PC speed, you can use hybrid hard drives (combination of both SSD and traditional HDD) to store all your documents and digital media files in hard drive and install applications as well as Windows on SSD area. 

How Hybrid Drive exactly works?

The way hybrid drives operate is pretty simple and easy to understand. It has no spindle motor and platter at rest most of the time which saves lot of power and produce much less heat as compare to mechanical hard drives, and thus heavily increases its life. As hybrid drives uses flash memorys buffer (not volatile in nature) to store data, there is no risk of loosing your valuable data when power failure strikes or system suddenly restarts.

Every time you access data from the platter, some extra amount of data is fetched and stored in the buffer. This is done in hope of future data requirements and providing fast availability for further requests, thus ultimately improves booting speed and keeps it reducing for further boot ups. The system speed will get increased to 4 times higher than it was before.

What so special about Hybrid Drives?

Seagate, the giant hard drive manufacturers, in 2007 introduced first flash chip based hard drive created by physically integrating both SSD and HDD, entitled Solid State Hybrid hard drives (SSHD) a.k.a. Hybrid drives. Though, Seagate announced their first hybrid drives release for public use in later 2010 named Momentus XT 7200 RPM.

Later, Western Digital and SanDisk join the trend and collectively introduced their first hybrid hard drives in the summer 2013, most thinly hard drive in history, named WD Blue. As like Momentus hybrid drive from Seagate, WD Blue uses the same small amount of NAND flash memory to boost performance and gives the same capacity to store large files. Itll available in various sizes from 8 GB to 24 GB of NAND flash memory and somewhere around 500 GB of hard disk drive capacity.

However, instead of using caching through firmware as in Seagate Momentus, WD uses driver software which is more relevant to computer operating system and readily improves PC speed even further as time passes on. However, this would suppose to be more prone to fail even by a low level of corruption to computer system and thus, your whole system might becomes unbootable.

This way, you can increase speed of using your PC up to 4 times. PC World experts has performed worldbench7 test on the Seagate 750 GB hybrid drives and found it little faster than the mechanical hard drives though much slower than the original solid state drives.


PC WorldBench 7 Test

Comparing capabilities of SSD, HDD & Hybrid Drives

Which one will best fits you or which is better among hard drive, solid state drives and hybrid drives? This is a quite typical question though, but fairly easy if youve a clear picture of what exactly you need either speed or performance or both.

Hard drive is a default storage device and used since decades ago.  It delivers the maximum storage capacity you need to keep you thousands of songs or even hundreds of movies. However, traditional storage technologies were failed to deliver the performance especially when the sizes filled with user data. Solid state devices were created to deliver the speed but limited in capacity and have high prices than hard drive. All the said devices are limited somewhere and wont provide all the benefits that is speed, performance and capacity.

To overcome these challenges, Seagate in conjunction with Samsung introduced the concept of hybrid drives by combining all the benefits of solid state drives and hard disk drives. This way, user will get the desired storage capacity and have enough capability to deliver the desired speed. Hybrid drives were specially created to overcome with failing or damaging problems and to be considered as very less frequent in dying or giving data loss phases throughout their life.

This article clearly explains points about the available high capacitive storage medias for current and upcoming generation. You can take joys of high speed environment while giving extra layer of protection to your highly sensitive data with these mightiest storage devices.
