Bug Description
Because Generation 2 virtual machines in Hyper-V are presented with a minimal set of EFI hardware, the kernel module "hyperv_keyboard" must be present to interact with the console keyboard. On systems with disk encryption, the user will be prompted for the key to decrypt the disk, but cannot enter the password because no keyboard driver is present.
This issue appears to exist in all Ubuntu releases that support EFI and are therefore eligible to be used as Generation 2 VMs, most recently tried with the April 5 ISO of the day for 16.04 (pre-release).
This module *is* present when the grub menu is presented and later when the kernel is fully loaded.
FYI, if some mechanism requires a mouse or touch, the hid_hyperv module will also be needed.
