Hi again,

>So domain 17 brought up vif7 right?
No, i've got no domain with id=17, last one is 16. Perhaps you mean the
name of the domain?
"xen-gentoo-default17" is domain 8 and the seventh' domain in order,
therefor belonging to vif8, because vifs and ids begin with 1 instead of
0...

No no, there is a domain with the name "xen-gentoo-default17", that
can't ping, but this has nothing to do with the amount of domains, there
are so ;)

Tried this now, did unfortunately no difference...

Any further ideas?
