3 virtual switches does not work

windstory · 16 Nov 2015

I've made 3 virtual machines at hyper-v on windows 10 x64 professional, also I made 3 virtual switches, but the networking including host does not work.

1. 1 external and 2 internal switches

The last photo is windows 7 vm.

I studied this guide - Hyper-V VM - Install CentOS Linux in Windows 10 Hyper-V VM - Install CentOS Linux in Windows 10 .

How to open 3 virtual machines at same time, with network working?

Any helpful comments would be appreciated.
Thanks in advance.

I think you have misunderstood something here. To connect all your virtual machines to the network and Internet, you only need one external switch. All your virtual machines should then use this same external switch. You don't need to use a different switch on each vm; in fact, if you do so, the networking between your virtual machines will not work because they all belong to different networks.

Short: create one virtual switch, set all your virtual machines to use it.

You are welcome. It's a common mistake that each Hyper-V virtual machine needs its own virtual switch.
