Centos 7 on Hyper-V yum problem

[hypercast]

Hello

I installed 6 VM centos 7 on hyperv.
All 6 vm cannot connect to yum repository.

After many troubleshooting I installed a VM on VMWare and yum works.
You know why?

The network and Dns are properly configured and works fine.

Thanks

What is the exact error message? Can you ping mirrorlist.centos.org ? If not, then your network is not set up properly.

Yes of course,
my network connection is properly configured.

Now I tried to install a Centos 6 but the same error even on Vsphere production and not on my Workstation.
So, the problem is not on hyper-v only but vsphere too, so I corrected the Subject.

The output of the commands are the following.

Thanks

Try with --disableplugin=fastestmirror

Sorry, but the command is correct?

yum --disableplugin=fastestmirror nothing to do.

thanks
