Just making it run is as simple as I wrote before, just 3 commands:
# apt install wget qemu-kvm
# wget
https://cloud-images.ubuntu.com/releases/16.04/release/ubuntu-16.04-server-cloudimg-amd64-disk1.img
# kvm -curses ubuntu-16.04-server-cloudimg-amd64-disk1.img
You should see it booting. I used a script to create fresh privileged
LXC container, but there's nothing kvm-specific in that script, just
some network configuration and user preferences. You said you use LXD,
but I don't think there's big difference.
You'll have to solve more problems to actually make it useful:
* give it more space with qemu-img resize;
* access virtual system: define password or ssh key with cloud-localds;
* share network with VM: -netdev bridge,id=br0 -device
virtio-net,netdev=br0,mac="$MAC_ADDRESS";
* configure static IP address: using cloud-localds rewrite file in
/etc/network/interfaced.d and reboot the system;
* share local storage with VM: -virtfs and mount with 9p.
* control VM with scripts: -monitor unix:... and socat;
* monitor boot with scripts: -serial unix... and socat;
* start and stop VM with container: systemd;
* ...
(br0 above is a bridge inside the container; you'll need to create it
and to forward /dev/net/tun for this to work.)
There's a lot of info about all this scattered throughout the internet,
but no single page; I'll think about writing details up somewhere.

Marat,
any chance you could share a little more about the steps you took to
start kvm manually? that'd be most useful to get things started. If
you wrote up that experience somewhere a link would be most welcomed too.
thank you,
Spike

Hello,
I was able to run kvm in a privileged lxc container without any
modifications of lxc stock config (well, with some related to network
bridge). I gave up on libvirt and start containers with
qemu-system-x86_64 and systemd. You may want to try downloading ubuntu
cloud image from
https://cloud-images.ubuntu.com/releases/16.04/release/
and starting it with kvm -curses to see if it works.
