With this config...

name = "builder91"
type="pv"
kernel = "/netbsd-XEN3_DOMU.gz"
memory = 16384
vcpus = 8
vif = [ 'mac=00:16:3E:74:32:42,bridge=bridge0' ]
disk = [
    'file:/tank0/builder91.img,hda,rw',
]

(and as seen in the path name, the image located on a ZFS dataset for 
the sake of quick snapshots) it seems to work flawless. Stress testing 
is still pending, but at least it boots into multiuser mode and provides 
normal response.

So in summary, the "mistake" was that ZFS ZVOLs are not suitable yet for 
beeing used as backend storage for Xen Dom U? While this is not so good 
news, I am still happy as I learned something more on Xen configuration 
today and want to thank all of you for your valuable input.

Kind regards
Matthias
