If you login in a console, "ip addr show dev eth1 scope link" should display it as "link/ether". It should be set to 52:54:00:f8:36:8f for our configuration to work properly. If the MAC happens to be another value like 00:15:5D:01:07:DC, which is the Image Factory default for MacAddress in the generated Hyper-V XML, eth0 would probably be renamed to eth1 - not 100% sure. You could also try to add 'config.vm.base_mac = "5254008815b6"' to your Vagrantfile before booting the box for the first time (that's only documented for VirtualBox, no idea if it has any effect on Hyper-V boxes).
