Apparently this is a known problem with Windows 7.  See for example
this long thread which has many suggestions but no solution:

  http://community.spiceworks.com/topic/148867-vmware-vms-switched-off-by-themselves

My suggestion would be to grab the event viewer logs from the shutdown
machine:

  guestfish --ro -d Win7VM
  ><fs> copy-out /Windows/System32/winevt/Logs /tmp

and you can decode these files using python-evtx (see:
https://bugzilla.redhat.com/show_bug.cgi?id=1109717) and see if
Windows is giving any reason why it wants to shut down.

In any case this doesn't seem to be a hypervisor issue.

Rich.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into KVM guests.
