But what about your old device, how to sell it, worrying about bargains/negotiations, Don't worry, is hassle free solution for all these that can help you sell your old gadget in matter of minutes and you will get instant Cash on your doorstep.

My experience of selling my Old Moto G4 plus

Well, i was quite bored of my old Moto G4 plus and wanted to get rid of the same this Diwali. Obviously, phone do have cons that provoked me to get rid of the same and get a new Smartphone with better features.

Now  my mind browsed for the options that  i can opt for Selling my Old device. 
I came across below Options.

1. Selling it Offline - Visited Nehru Place market.
2  Flipkart / Amazon exchange policies.
3  Selling via OLX
4. and it worked smoothly.

I will discuss above options one by one.

Fisrtly, i visited Famous Gadget Market in South Delhi - Nehru place as there are several shops that buys old gadgets like laptops and mobiles, I showed them my Moto G 4Plus but i was not getting the required return, The highest price i was offered was merely Rs 2200 that was way too low, so i did not opted this option.

Secondly, I visited Flipkart and Amazon that allows us to sell our old mobiles as exchange policy in case you are planning for purchasing new one, it offered better return than Option 1 but still it was not much convincing, Moreover Rs 100 is charged as picking charges and secondly this option can only be used if you have to Purchase a new one that means you have to spend more to get rid of old device. As per exchange, i was getting 3800 - 100 = Rs 3700 for my device, but i have to spend 11,299  more to get rid of my old device that is the disadvantage of exchange policy.

Thirdly, I tried posting ad on Olx, but  again, i did not found it much useful as there are too much bargains and negotiations in the process and i found it not safer to sell my device to a stranger  who can later on ping/contact me for any issues occurring in device later post selling. Process was full of negotiations,So, i cancelled this option.

> Well Fourth one, that i found really great is none other than

I visited the site and checked for the price that i can get for my Old Moto,it asked some questions regarding my Device status like whether it switchs on or not, Is there any feature that do not work,we need to select that Feature, I must say The Site interface was very User Friendly, Other info gathered was warranty info, after giving all the details, I got instant Quote of Rs 5450, now that is a Great Deal for my old moto g4  and I was really happy to see great return for my old mobile.

Device was quoted for Rs 5450, that's more than Flipkart or any other option i explored till now and other selling choice/offers (Amazon, Myntra vouchers) gave more value than Cash (upto Rs 6250), which is another advantage.

Well, i scheduled the pickup time slot as per my convenience and Sold the same without any fuss or difficulty

How it works : Watch Below Video:

Below are the Pros of Selling Your Old device/gadget on Cashify:

1.  You will get best selling price of your  old Gadget.

S. NoOptionMaximum Price Offered in INRComment

How to Install and Configure KVM Hypervisor on RHEL 7

Leave a Comment
KVM stands for Kernel based Virtual machine is open source Virtualization infrastructure for Linux Kernel that turns Linux server into a Hypervisor that allows you to run multiple Linux and windows based machines.

KVM architecture

Also read : Boot process in Linux 

Prerequisites :

Check for Hardware compatibility for running KVMs

First precheck or prerequisite is to check whether our hardware/CPU  supports it or not. Run below command to check the same. If below command returns either vmx or svm in the output, that means our hardware is fine  for KVM and having  required CPU virtualization extensions.

For Intel based Hardware : vmx
For AMD based Hardware : svm

[root@himanshu ~]# cat /proc/cpuinfo | egrep 'vmx|svm'

Install KVM packages using Yum 

Below packages need to be installed on your Linux machine for installing  KVM hypervisor.

[root@himanshu ~]# yum install qemu-kvm qemu-img virt-manager libvirt libvirt-python libvirt-client virt-install virt-viewer bridge-utils

 After installing the packages, start and enable the libvirtd service (Virtualization daemon)

[root@himanshu ~]# systemctl start libvirtd
[root@himanshu ~]# systemctl enable libvirtd

Run below command to check if KVM modules are loaded in kernel or not.

[root@himanshu ~]# lsmod | grep kvm
kvm_intel             170181  10
kvm                   554609  1 kvm_intel
irqbypass              13503  1 kvm

Check whether virt-manager tool is opening the GUI based tool to manage/launch machines.In case, same is not opening, install below x-window package and restart the server and check again.

[root@himanshu ~]# yum install "@X Window System" xorg-x11-xauth xorg-x11-fonts-* xorg-x11-utils –y

[root@himanshu ~]# virt-manager

Running virt-manager will pop up window (GUI tool)by which you can manage KVM machines.

Configure Bridge Interface 

If you want to access Virtual machines outside hypervisor network, you need to configure Bridge interface as below.

[root@himanshu ~]#cd /etc/sysconfig/network-scripts/
[root@himanshu ~]#cp ifcfg-eno49 ifcfg-br0
[root@himanshu ~]#cat ifcfg-eno49

[root@himanshu ~]#cat ifcfg-br0

[root@himanshu ~]#systemctl restart network

Hope you have successfully installed and configured KVM hypervisor on your  RHEL/Centos 7 machine. Now you can easily start creating machines.

Unboxing WD My Passport 1 TB Wired External Hard Disk Drive with Saco Back Cover - Review

Leave a Comment
Our storage requirements are increasing day by day, Earlier we were  having computers with hard disk of 100 GB capacity that was considered to be very high at that time,also our data requirements were low those days, but  now 1 TB hard disks have become very common and storage requirements are increasing day by day. Be it anywhere, Home, Internet business or enterprise, data is growing at a great pace and  this Big data that is known subject these days also known as Hadoop

If  your  internal drives become full and you don't want to delete any stuff, don't worry- External  Hard Disk Drives will come to rescue and will help you to save all you important data, on the other hand if you want to take backup of huge data say 500 GB that is not feasible for storing over cloud, same can be backed up over External hard drives.

Recently, my old buddy storage  - Dell Inspiron 14r (6 years old) almost reached almost 90% and was not able to find any thing that can be deleted and was not in mood to delete old movies, Favorite Tv series, so i thought about buying a new External  Hard disk drive.

Why WD  over other brands ?

Coming over choosing brand, there are many players in market, WD, Seagate, Toshiba, Adata, Sony, Tracend, without any single thought, i selected WD because i have great experience with WD earlier when i replaced my Faulty WD hard disk back in 2012  drive without visiting Service centre, WD is the brand  that provides great after sale service to their Customers. My passport hard disk drive comes with 3 years limited warranty, that means physical damages are not covered.

Analyse your Storage requirement

WD offers external Hard drives with 1 TB, 2 TB and 4 TB capacity, analyze your storage requirements and go for it.

I ordered WD  My passport hard disk of 1 TB Capacity on Flipkart and here are the unboxing images  of the same.
You can get WD My passport for around Rs 3500 - 4000,  i ordered the sane during big billion days so got  SBI bank offer that offered 10% instant discount. The product was delivered in 3-4 days and packing was fine.

The product was protected by air bubble sheet as shown below.

Inside the package, there was My passport Hard Disk Drive, Connecting cable and manuals

In order to keep the hard disk safe, i ordered Saco back cover that is shock proof and prevents damage  to hard drive in case same is fallen, dropped or mishandling, It has separate pocket for cable and hard drive and can costs you for Rs 200 - 300 and it is a great investment to  ensure safety of WD Hard drive.
