It seems some misconfig in HyperV, try to install clean Centos 6.7 then install from NS Repo.
and how about /dev/root does not exist? on Stuck3 ?
ok, i will use the same virtual machine with 6.7 iso…you said Hyper-V missconfig…but read this https://bugs.centos.org/view.php?id=9860
i work with version 6.7 successfully on a PC. I just wanted to test the version 7.2 with the iso on a virtual machine. The update method is laborious to me because the internet connection here is of poor quality with only 512kbps, of which only a quarter of link to Internet.
try to input this option to kernel why not 
if it is this bug it will fix it :
initcall_blacklist=clocksource_done_bootingThanks for your effort!
I searched a bit, but I didn’t found any CentOS7 related bugs over Hyper-V, in fact is seems fully supported:
Looking to dracut error, I’m wondering if this is caused by a misconfigured root partition in the kickstart.
Can you please try to install a clean CentOS 7 using the NS iso?
i’m currently using the iso!!!
I know, but try to install a plain CentOS 7 not NS.
sorry!! ok, i’ll try

Press “e” and add this at the end of the line
initcall_blacklist=clocksource_done_booting
I tried that option. Unsuccessfully

somth strange, please share Teamviewer credentials, i will take a look
Just another shot: can you also try with a vanilla ISO from CentOS site ( http://isoredirect.centos.org/centos/7.2.1511/isos/x86_64/ ).
If the problem still persists, this is an incompatibility regarding RHEL/CentOS 7 on some Hyper-V configurations (not NS related), otherwise it’s a bug in our ISO building process.
I can not accept TeamViewer connections… is prohibited here …Maybe someone can reproduce the problem. Someone who has installed and use hyper-v R2 20012
I’ll put it in the download queue. It may take a couple of days … due to bandwidth constraints we have.
is this enough?:

Yes, it’s the right iso. Thank you for your time 
why do you think that you do not need additioanal LINUX drivers for HYPER-V ?
