I regularly install 12.04 and 14.04 Ubuntu vanilla isos in KVM using
virt-manager as a regular user. The only subtlety is when bridging
to an external physical adapter which I solve using a manually
defined bridge (as root) like you described earlier. It appears
Network Manager in 14.04 supports bridges so this may not be
necessary.<br>
<br>
What type of disk do you use for your VM in KVM?<br>

In a nutshell, start with the Ubuntu Amazon EC2 images (not
the regular server ISO image), then create and use an
additional init ISO image so it would allow password login,
then once you login you can add your ssh key.<br>
<br>
</div>
<div>By adding a MAC address, you get your DHCP server to assign
it a known IP address, and then you can ssh to that. No VNC
required, no console!<br>
<br>

But, yet again, all this was not needed with VirtualBox ... sigh

<div>Another difference between libvirt and VirtualBox.<br>

I was able to take the Ubuntu Server stock .iso file, and
install it inside of VirtualBox normally. That includes
installing grub in the virtual disk's MBR.<br>
<br>
With libvirt, grub installation does not complete, with no
errors. The step proceeds, then returns to the tasks.<br>
<br>
So, I am unable to have a working VM with KVM and libvirt
so far because of grub aborting.<br>

From memory, QEMU simply adds its tap
interface to existing bridge. I<br>
had to setup bridge and add wlan0 (my
wireless connection) to it. Then,<br>
the virtual machine got its IP from the
wireless router.<br>
