Public bug reported:

Eachtime I'm trying to start VM through Virtual Machine Manager an error
window appears:

Error during domain starting: internal error: Cannot find suitable CPU
model for given data

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 96, in cb_wrapper
    callback(asyncjob, *args, **kwargs)
  File "/usr/share/virt-manager/virtManager/asyncjob.py", line 117, in tmpcb
    callback(*args, **kwargs)
  File "/usr/share/virt-manager/virtManager/domain.py", line 1162, in startup
    self._backend.create()
  File "/usr/lib/python2.7/dist-packages/libvirt.py", line 866, in create
    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: internal error: Cannot find suitable CPU model for given data

The workaround found is to run:

sudo dpkg-reconfigure libvirt-bin
libvirt-bin stop/waiting
libvirt-bin start/running, process 16631
Setting up libvirt-bin dnsmasq configuration.

After this VM starts running. But till next system reboot. After
restarting computer I must run dpkg-reconfigure again to make VM
starting.
