Can't install NethServer 7 ISO on Hyper-V

I downloaded the iso and tried to install it: Not working on hyper-v 2012 R2 2nd generation virtual machine. Someone else tried?

What do you mean not working on hyperv?

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
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 :slight_smile: if it is this bug it will fix it :


Thanks 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

the same errors after this:

Press “e” and add this at the end of the line


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 ( ).

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 :smile:
