I have a Xen 3.0.4 with Debian Etch (4.0) running quite successfully...

except for an annoying problem, which i have not observed in other
DomU instances, nor have I observed it with my test server...

The problem I am observing in that one domain is that on reboot, the
eth interface seems to "wander" - that is  monotonically increase the
index value...

so on one reboot  it will be eth0 on next eth1, on one after that eth3
and so on.
Of course this causes all sorts of scripts to fail, and manual
intervention is required.

has anyone else seen this misbehaviour?

Is there a method of pinning or making this behaviour consistent?

Tomasz
