[MirageOS-devel] xen issues

[Richard Mortier <Richard.Mortier@xxxxxxxxxxxxxxxx>]

having fixed the previous problem (with some assistance from dave :)  i can now 
build a xen image but not successfully start it. this is true of my website and 
of mirage/lib_test/basic.  i get the output appended below (trying to start the 
combinator example in mirage/mirage).

i'm not very familiar with interpreting these logs -- anyone any suggestions?
