Yeah I'm pretty sure this is a dupe of bug 1626070.

Title:
  libvirt fails to start VirtualMachines

Status in QEMU:
  Invalid
Status in libvirt package in Ubuntu:
  Confirmed
Status in qemu package in Ubuntu:
  Confirmed

Bug description:
  I've created several kvm based machines using virtual machine manager.
  They have operated well over the last 4 days without issue. I did an
  apt-get upgrade, and qemu was in the list of updates.

  After upgrading, I am unable to start any of the provisioned virtual
  machines with the following error output

  virsh # start node2
  error: Failed to start domain node2
  error: internal error: process exited while connecting to monitor: 
qemu-system-x86_64: -machine trusty,accel=kvm,usb=off: Unsupported machine type
  Use -machine help to list supported machines!

  virsh # start node3
  error: Failed to start domain node3
  error: internal error: process exited while connecting to monitor: 
qemu-system-x86_64: -machine trusty,accel=kvm,usb=off: Unsupported machine type
  Use -machine help to list supported machines!

  $ dpkg -l | grep kvm
  ii  qemu-kvm                             2.0.0~rc1+dfsg-0ubuntu3             
amd64        QEMU Full virtualization on x86 hardware (transitional package)

  Log snippet from vm 'media' that was verified working, and fails to
  start after the upgrade.
