In this post, we are going to learn about the virtualization concepts of VMware. Evolution of Virtualization helps in Data Center optimization. Before virtualization every single application used to be maintained on a physical server, which leads to hundreds of servers' maintenance, power consumption, Data Center maintenance, License management, support and many.
Using Virtualization concept we can create around 50 virtual machines (may be more, sometimes less) on a single host machine depending upon resources of the base machine. Base machines are high end servers with great configuration. To create and manage such virtual machines (VMs) on top of the host we need a Hypervisor, which is responsible to manage VMs.
In my earlier posts, there are posts related to LDOMS Manager (Logical Domains) which is installed on top of the hypervisor and then we can create and manage ldoms within that host. Similar to ldoms concept the VMware released the ESXi hypervisor which needs to be installed on host machine and within that host box we can create multiple virtual machines. Entire host machine resources will be virtually assigned to the VMs by the hypervisor.
Let's see how to install VMware ESXi hypervisor on base or host machine...
Here I created a basic virtual server on my Oracle Virtual box, since it is easy and everyone knows I am sharing a simple screen where you can see basic requirements..
Loading Part...
This will take sometime, to load every file...
Click Continue, to proceed with installation...
Accept the License agreement...
Selecting the Keyboard layout...
Warning regarding virtualization...
Warning regarding re-partitioning of the disk...
Installation started...
This takes sometime,
After sometime...
Reboot the system upon completion of installation of ESXi...
Booting the ESXi...
Our DHCP (Dynamic Host Configuration Protocol) server will assign an IP as per our range and its availability...
Open the browser, enter this IP in the url and then we will be redirected to the VMware website where we can download our vSphere Client and vCenter Server softwares. I missed those screens, but it looks like:
Install the vSphere client in your local machine... Open it ...
Enter the login credentials and the IP of our ESXi host...
Ignore it since we are not using SSL certificate....
Home Screen of our Host...
If we login it from our VM , it looks like...
Since we are provided with DHCP IP if we want, we can assign a static IP...
This is how our IP configuration screen looks..
I am making this IP static, by providing a netmask and a default gateway...
Click "YES" to finalize...
Try logging in again....
Thats it done with the installation part, now try creating virtual machines. Now our host is all set to create and manage VMs using its resources...
