Or use excel to make a WKT column and import that.

This is relatively straightforward in QGIS master:
- import your CSV file
- right click the CSV layer, and choose "Save as"
- change format to "ESRI Shapefile". Choose the correct CRS for your
coordinates.
- expand out the "Geometry" group and change "Geometry type"
from
"Automatic" to "LineString"
- click OK, the new LineString shapefile (with all null geometries)
will be added to the project
- now, you need to create the geometries. This is done through the
field calculator.
- tick "update existing field"
- change the field to "<geometry>"
- enter the expression:
'make_line(make_point("x1","y1"),make_point("x2","y2"))'
(but replace
x1, y1, ... with the correct columns names from your original CSV
file)
- click OK. Done!
