I had Hyper-V and Ubuntu running on Windows 8 no problem. I've since done a fresh install to 8.1, and I can no longer create an External Virtual Switch. The button for "Create Virtual Switch" is grayed out when I select "External". I can create Internal and Private switches, but not External. There's no error or message so I'm having difficulty troubleshooting. All of the tutorials I've seen don't talk about any configuration I would need to do before creating an external switch. Any ideas? I have the default Windows 8.1 firewall and antivirus stuff.
I tried creating the Virtual Switch in PowerShell with the following commands
PS C:\WINDOWS\system32> Get-NetAdapter
Name InterfaceDescription ifIndex Status MacAddress LinkSpeed
---- -------------------- ------- ------ ---------- ---------
Ethernet Realtek PCIe GBE Family Controller 3 Up B8-97-5A-13-7C-E6 1 Gbps
I'm not really sure why it couldn't find my physical network adapter, since it shows up with the Get-NetAdapter command.
PS C:\WINDOWS\system32> New-VMSwitch -Name "TestNew" -NetAdapterName "Ethernet" -AllowManagementOS $True
New-VMSwitch : Cannot find a physical network adapter named Realtek PCIe GBE Family Controller.
