I have installed Ubuntu Core 16 into a QEMU/KVM virtual machine using 
the GUI frontend "Virtual Machine Mamanger" (package virt-manager).

For this I click the "New machine" icon at the upper left of the main 
window of Virtual Machine Manager and on the first screen of the setup 
wizard I choose "Import existing disk image". Then I uncompress the 
downloaded image file with "unxz" in the terminal and copy it into the 
image directory of the Virtual Machine Manager (optional, to avoid a 
file not owned by my user ID in my home dir):

unxz ubuntu-core-16-amd64.img.xz
sudo cp ubuntu-core-16-amd64.img /var/lib/libvirt/images/Core16.img

In the second screen of the setup wizard I click "Browse ..." at the top 
right and choose the Core16.img file. Back in the wizard I choose OS 
type "Linux" and Version "Ubuntu 16.04". On the next screens I choose 
2048 MB of memory and 1 processor core (you can choose other values 
dependent on you hardware and number of VMs running in parallel) and as 
name I enter "Core16". All the rest I leave on default.

After finishing the wizard Virtual Machine Manager takes some seconds to 
set up this configuration, adds the new VM to the list in the main 
window and pops up a window with the virtual screen of the VM on which 
you see the boot process.

Once the boot process has finished, the text-based setup wizard of 
Ubuntu core appears in the machine's window and asks for the network 
connection. Choose the default which is a "wired" connection with the 
virtual NAT router of the Virtual Machine Manager (or QEMU/KVM?). The IP 
should be something like 192.168.122.XXX. After that enter the e-mail 
address of your store account and the wizard finishes.

Now I can log in via

ssh USER at 192.168.122.XXX

replacing XXX by the user name which Ubuntu Core has assigned to me and 
XXX by the appropriate part of the IP address.

This login does not require any password.

I do not know how to login in the window with the screen of the VM. I 
tried no password and the store password and it does not work. I can 
only use SSH for now.

As the Virtual Machine Manager uses a virtual NAT router and so the VMs 
have their own IP addresses SSH simply works through its standard port 
22 and does not need the "-redir".

This is my experience for now.

I hope someone can help me on logging in on the machine's own virtual
