Hi Norm,
That was a cut and paste error in my email.
The virtual file is okay: mgwi.ovf
I tried the mapfile LABELITEM suggestion:" may need to use table.name or
just name depending on your OVF file".
I also tried a relative and absolute CONNECTION in the mapfile.
I keep on getting the following message:
msDrawMap(): Image handling error. Failed to draw layer named 'MGWI_TBLLOC'.
msOGRFileOpen(): OGR error. Open failed for OGR connection
`D:\webCGCq\lcnp\mapserver_demo\maritimes\data\shp\geo83\mgwi.ovf'. File not
found or unsupported format.

Connectiontype)
Julien,
What is the exact name of your "ovf" file? Because the name you
specified in the "CONNECTION" parameter in the map file does not match
the one given for you "ovf" file.
See in your email below: "Here is my virtual file (mgw.ovf):"
See your "CONNECTION" parameter into your map file for your specific
virtual layer:
...
CONNECTIONTYPE OGR
CONNECTION "mgwi.ovf"
...
