gzt: ^ That is hyper-v bare metal.

That one is different to adding the hyper-v role in windows server or adding the hyper-v role in windows desktop operating systems.

When you install the hyper-v role on a host os, it kind of also virtualises the host os to some degree in that the management os runs as a guest, but not quite the same as a proper vm.

Good point. It's clear my comment is in error.

Is that why my internet connection is dodgy?!

VMWare is better then?

Yes I guess that you can argue that, but most of the people in this thread are not going to need to understand the distinction and it really does confuse the topic at hand :-)

While we are derailing with unneeded technical detail however, I run quite a lot of servers at work with boot to VHD, so I feel somewhat qualified to comment. It's completely below the hypervisor layer, you can go read the MS documentation but a tldr explanation is the bootloader in the EFI system partition mounts the VHD file, and presents it as another disk and then boots off it.

For an example configuration, imagine a machine with a single physical drive. The disk has the efi bootloader partition at the start, then the rest of it is a single NTFS partition. The NTFS partition on the first disk contains a VHD, and the bootloader is configured to boot from the VHD. When you are booted into windows, you'd see the following in disk manager:

Disk0 containing an EFI system partition (not mounted) and an NTFS partition mounted as D: (The physical disk)

Disk1 containing a single NTFS partition, mounted as C:, marked as the boot partition and containing the OS (the contents of the VHD)

Yep. I've never been responsible for virtual services. Just my own use in testing/development type use. Vhd native boot has been around since windows 7 and does not require a hypervisor installed.

Depends what you mean by dodgy. On the virtual client network configuration side you can choose between NAT -, and 'Bridged' directly connected to the network with a unique ip address.

In VMware the default is NAT but it's easily changed. I don't recall for hyper-v but most likely similar. Bridged will get you less issues if that's the problem.

Btw assumed you meant a virtual client side problem. If the problem is with your workstation, different answer : ).

Actually, I was trying to balance the post between the original question and those that might be reading at a later date (or re-reading when they have used said product a few times).

I dont appreciate the unessary put-down - I dont see that those kind of personal focused comments are needed in a technical post.

In hyper-v you get several [switch] options for networking - private - this allows you to isolate everything on its own network. This can be good for development and testing as one can run a dev network and a test network and have the VMs on them isolated from each other. The caveat is that the VMs do not have access to the host machine. Internal networks are similar, except the VMs have access to the host machine, it is possible to use NetNat to give access to the host machines LAN. External networks basically virtualise/use your installed network cards.

In the VM there are two network card options - a generic network adaptor (I think this supports up to 10Gbe) and a legacy network adaptor (this emulates a DEC 2140 10/100TX card and is used for PXE boot for example, when using Windows Deployment Services).

In a server environment NetNat can be replaced by RRAS.

Last but not least, all of the networks can be configured with VLAN tagging.

Wasn't intended to be a put down at all. Apologies if you took it that way.

No, problem with workstation. The wifi that it was connected to had a different name to the original wifi connection, and everything loads very slowly, some pages not loading; like broken DNS. So deleted the virtual network switch for now, and accidfentally deleted the server on hyper-v (don't remember creating one! ?) so now need to figure out what to do - will do some googling

Ok after fumbling around for a few weeks I have my virtual PC working!

Because I used a legit key AND i use my virtual pc for testing, I have a high chance of breaking it.

What is the best way to back it up before I do anything to it?

Either right click it in Hyper-V Manager and select checkpoint from the right click menu, or left click select it and chose Checkpoint from the lower portion of the Actions pane.

Also, if you like to automate things, or just like PowerShell in general, you might want to check out the Checkpoint-VM cmdlet

What if I just copied the vhd file would that work?
