Can't install NethServer 7 ISO on Hyper-V


(luisr) #1

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

Try out NethServer 7 alpha2 ISO!

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.

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?

(luisr) #10

i’m currently using the iso!!!

(Giacomo Sanchietti) #11

I know, but try to install a plain CentOS 7 not NS.

(luisr) #12

sorry!! ok, i’ll try

(luisr) #13

the same errors after this:

(Artem Fedai) #14

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


(luisr) #15

I tried that option. Unsuccessfully

(Artem Fedai) #16

somth strange, please share Teamviewer credentials, i will take a look

(Giacomo Sanchietti) #17

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

(luisr) #19

I’ll put it in the download queue. It may take a couple of days … due to bandwidth constraints we have.
is this enough?:

(Giacomo Sanchietti) #20

Yes, it’s the right iso. Thank you for your time :smile:
