How to install Centos 7 on hyper-v windows Server

To install centos 7 on hyper-v windows Server

Step-1: in hyper-v manager select the host machine and right click –>new –>virtual machine

Step-2: follow the wizard

give name to vm

Step – 3: choose the generation

we will be using the generation 2 to take advantage of some of the features.

Step – 4: Assign the memory for the server

[ the host server i am using got plenty of memory for me to play around so i am giving this vm 8gb]

*not using dymanic memory at this movement , from my understanding using dynamic memory will allow me to over provision the memory. Basic idea is that not all vms will be using 100% of its memory which are allocated to them, by backing on this principle we can allocate limited memory to multiple vms ie.,for example 8gb host memory can be allocated to 5 x2gb vm with dynamic memory allocation, here 2gb memory over provisioned against 8gb actual memory. this popular practice for many vps hosting companies 20% to 25% of memory are over provisioned.

Step –5: Assign network connection interface.

*the best practice is usually have a separate interface for guest vms and host server esp if you have multiple vms, gives you best network performance.

Step-6: Define virtual hdd.

I am going to live this to defaults, as i already move my default location to E: against the usual location in c: drive.

Step-7: Select the install media

you can either mount the iso later when you switch on the vm or assign it now.

i am going to mount cento7 minimal install iso now

Step-8: Verify the summary

it might be a good idea to copy the summary for future reference and hit finish

Step-10: Now the machine is created, you have to switch it on to continue further, before that some settings still need to be tweaked.

Step -11: Adjust the vm settings before turning it on

right click on the vm –> settings

Step – 12: goto the firmware under hardware panel and disable the secure boot option

Step-13: adjust the boot order, move the network boot to last and hdd boot option to second

Step-14: adjust the virtual processor,

depend on the need adjust the number of virtual processors, and tweak the reserves for this particular machine, i am going to give this machine 4 virtual processors and leave the rest to defaults

Step – 15: under management panel,you can adjust the other options like integration services, i am going to enable the guest services too, its optional not really necessary

other options like paging fine location can be moved to ssd hdd if you have one to help improve the preformance, if not can just leave them alone

Automatic start & stop actions helps to define how the hyper-v should behave during start up and shutdown of hyper-v services.

Step-16: Setting vm to start automatically after the host server boots up

under automatic start action, change to always start this virtual machine automatically and it might also be a good idea to put some start delays so it does not over load the machine during boot up process.
