Dear Curtis,

First of all, thanks for your answer!

Two new facts:

1. I've done what you said (commenting out the vif= line), but the result is
the same :(

2. Sometimes, I get a slightly different error message than the one I
reported originally ("Backend device not found" instead of "Hotplug scripts
not working").

tornado:~# xm create test.cfg -c
Using config file "/etc/xen/test.cfg".
Error: Device 2049 (vbd) could not be connected. Backend device not found.

The error message type doesn't seem related with the vif= line. In other
words, I've get both of them either commenting or not commenting the vif=
line, although "Backend device not found" seems to be less frequent (see
typescript of the test at the end of the mail).

What is the exact meaning of each one of this error messages? What is the
device number 2049?

Any new piece of information/test ideas is very welcome...

Thanks again!

Best regards,
