If you're talking about domU, then it's normal. Whatever the block
device is on dom0 (/dev/etherd/*, /dev/mapper/*, etc.) domU sees only
/dev/xvda (or whatever you tell it to be).

I'd start by looking at this. The error says /dev/etherd/e0.1 while
your xml says otherwise.
You could also try using "xm block-attach", which is simpler.

When everything works correctly, it should appear as /dev/sdh on domU.
