I have updated the libvirt and xen from
the f20 latest updates and forced all the scripts back to their
unadulterated state.
I believe that I am now seeing libvirt passing a -1 devid to libxl
expecting libxl to chose the right one.
There was an email thread about this problem. " Setting
devid for emulated NICs (Xen 4.3.1 / libvirt 1.2.0) using libxl
driver".
I read through email chain but I did not see a resolution.

One more quirk
I can create a domain using the lx commands and a slightly
modified
.conf file.
"virsh start kvmtest" returns a failure.
I tracked the information passed to vif-openvswitch and it is
being
called with type_if=tap and it needs to be type_if=vif.
Sounds like a Xen bug. Does it call vif-openvswitch twice?
Once for an
emulated NIC and once for PV nic?
openvswitch is called twice once with ACTION="" and again with
ACTION=""
Any help would be greatly appreciated
once again.

Shouldn't that be '...,script=vif-openvswitch,...'? Also, if
your guest
has PV drivers, you could set 'model=netfront' to explicitly say
you
only want the PV NIC.
Your correct. I hand fixed it and ran my tests but then foolishly
reran domxml-to-native overwriting my fixes.
I gave various nic configurations a try and e1000 was just the
last one before moving to looking for the problem in other places.
I will likely use the PV nic for any real systems but now I am
just trying to get the kinks out.
