How do I upload an ISO to the Hyper-V data store?

Solution 1:

Hyper-V works a bit differently than ESXi. You don't create a datastore and upload ISOs to it, you create a VMM library share and put your ISOs there.

This would be done with Virtual Machine Manager, which is the rough equivalent of vSphere in the Hyper-V world.

Solution 2:

Another way to do this is to go on the server and create a share. In my case, I ran:

net share "Downloads=C:\Users\Administrator\Downloads" "/GRANT:EVERYONE,FULL"

which is terribly insecure but fine if temporary and on a restricted network.

You can then access the ISOs you push in the Hyper-V Manager settings when you set the CD/DVD-ROM ISO.
