Hyper-V support for CentOS 7.3

[wickedviking]

Due to the way Hyper-V handles virtual switches the name of the virtual switch must be passed as an environment variable.

Can be obtained via: Get-VMSwitch in PowerShell.

Example packer build command

packer build --only=hyperv-iso -var 'hyperv_switch="Your vSwitch Name"' .\centos-7.3-x86_
64.json

Several changes were required for the ks.cfg

• network --bootproto=dhcp --onboot=on --device=eth0 forces the network to be available for %post
• reboot --eject forces ejection of the install media after first reboot, otherwise you end up in the installer again
