📎 AI Summary:
The thread discusses why Hyper-V virtual machines (e.g., Windows 7/Vista/XP) can fail to access the internet after setting up a virtual switch, and what to do to restore connectivity. The main answer is that Integration Services must be installed inside the guest OS, but the required service components won’t install unless the guest OS has the proper service packs first; users may need to download missing SPs and, on newer Windows versions, can mount the VM VHD to copy the SP installers in before running them. Overall sentiment is practical and helpful, with the respondent providing a workaround and noting that VHD mounting simplifies transferring files into VMs.

Installed VMs in Hyper-V such as Win7, Vista or XP want to connect to the Net.

After, installing a VM OS & setting up a Virtual Switch the VMs may see no internet connections.

The Integration Services must be installed to the VMs to have connectivity. These will not install unless & until all required SPs are in FIRST (SP1 & 2 for Vista and SP1, 2 & 3 for XP).

If the install media did not give all SPs, download them. Next, in Windows 8 the VMs can be mounted. Find the VHDs, Rt Clk & select Mount. Now, you can copy the SP files to the VM. Eject the mounted VHD (They won't run in Hyper-V, if you don't. Now, in the VM > C:\ find the SP(s) & install. Once done, the Integration DVD will (now) work/run in the VM and NOW the VM will connect to the Web.

BTW, being able to mount the VHDs makes it really easy to copy or move things to your VMs.

Cheers,
