[virt-tools-list] AttributeError: type object 'VirtualAudio' has no attribute 'MODEL_DEFAULT' -- virt manager 0.8.4 requires virtinst 0.500.3 but then fails to open guest windows

[Michael Cook]

I have Centos with the latest patches running XEN dom0 and several RHEL guests.
In the original installation the Virt manager happily opened the guests using the "Open" option on the guest that appears in the virt Manager.

I then applied some patches from regular yum update, I've tried downloading and manually installing Virt Manager and VirtInst and now I have the problem that the Virt Manager tries to open the guest window and gets:

Traceback (most recent call last):

Using 
these two packages, manually compiled and installed...
virt-manager-0.8.4
virtinst-0.500.3

Any clues on what I need to do on the host or xen guest configuration file?  I've tried added a vnc server configuration to the guest config file but this just says connection refused.
