XEN-4.4.0-release Failed to open connection to gnttab

["bobbisanchez@gmx.de" <bobbisanchez@gmx.de>]

Hi

i am trying to get XEN-4-4.0-release to running under NetBSD 6.1.3 (amd64)
i am using the usually way as written on the wiki

this is my rc.conf XEN part:
xencommons=YES
xend=YES <------ XEND does not exist, but without an entry inside the 
rc.conf xencommons complains about missig XEND on boot
xenwatchdog=NO

while the system is booting i get some error messages:

(I dont know if that is ok if i post the bootlog here so i am using 
pastebin)
http://pastebin.com/raw.php?i=YTW5L2Nj

then after login i need to set the   "export 
LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/usr/pkg/lib"

the configure that i use:
./configure PYTHON=/usr/pkg/bin/python2.7 
APPEND_INCLUDES=/usr/pkg/include APPEND_LIB=/usr/pkg/lib --prefix=/usr/pkg


but what means, as you can see in the bootlog:
Starting xenservices: xenstored, xenconsoled.WARNING: Failed to open 
connection to gnttab

thank you very much
best regards
