I have resolved my problem by running kernel 3.14.1-031401 from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.1-trusty/, Ubuntu
14.04 LTS.  The host has been running solid for a good 24 hours with 1
Windows Server 2008 R2, 2 cpu, VM running and two additional VMs running
for three hours.

The pertinent xml entries that were changed or not included in the
original xml configuration file are

  <os>
    <type arch='x86_64' machine='pc-i440fx-trusty'>hvm</type>   #changed from <type arch='x86_64' machine='pc-i440fx-1.7'>hvm</type>
  </os>

  <features>
    <hap/>   # added entry
  </features>

  <clock offset='localtime'>
    <timer name='hypervclock'/>   # added entry
  </clock>

I'm not sure what will happen when a kernel 3.14 is included in the main
distribution.  Will the future kernel 3.14 from the distribution replace
the 3.14 kernel that was installed via dpkg?

Thank you for everyone's messages.
