xen discuss - Aug 2008 - Device 0 (vif) could not be connected. Backend device not found.

I am getting the following error when attempting to use virt-install to create a
DomU.  I am getting the error whether attempting to create an OpenSolaris DomU
or Windows Server 2003 DomU.

Dom0:  SunOS unknown 5.11 snv_94 i86pc i386 i86xpv

OpenSolaris virt-install:  virt-install --nographics -n ostest --paravirt -f
/dev/zvol/dsk/rpool/ostestd0 -r 1024 -s 16 -l /tmp/os200805.iso

Win2003 virt-install:  virt-install -n win2003 --hvm -r 1024 --vnc -f
/dev/zvol/dsk/rpool/win2003d0 -s 16 -c /tmp/en_win_srv_2003_r2_enterprise_
cd1.iso

I have attached the complete output for the OpenSolaris virt-install which is
identical except for the name and time stamp to that of the Win2003 virt-install
output.

Let me know if you have some guidance on diagnosing this problem.

Please provide the output of ''dladm show-link''.

-bash-3.2# dladm show-link
LINK        CLASS    MTU    STATE    OVER
nfo0        phys     1500   up       --

I''m not sure if nfo is gldv3 compatible...
Could you please run below command as root and send us the output:
# /usr/lib/vna nfo0 aa:00:11:22:33:44

After reading the information for the nfo driver more carefully, I saw the
instructions for recompiling the nfo driver with GLDv3 support. 
http://homepage2.nifty.com/mrym3/taiyodo/eng/

I installed the gcc-dev package and followed the instructions that came with the
driver.

I was getting an error during compilation and I found the a thread were the
problem was discusses and solved. 
http://opensolaris.org/jive/thread.jspa?threadID=60123&tstart=195

I downloaded the mac.h and mac_ether.h files from
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/sys/. 
I put them in a sys directory in the same directory where I extracted the driver
source.  Then I modified the Makefile.config_gld3 file in two locations.

#ONUTSDIR = /home/mrym/opensolaris/usr/src/uts
ONUTSDIR = /export/home/me/Documents/nfo-2.6.0

and

#ONUTSDIR = /home/mrym/opensolaris/usr/src/uts
ONUTSDIR = /export/home/me/Documents/nfo-2.6.0

This allowed me to compile and install the driver.  

After doing this I am able to use /usr/lib/vna to create a virtual nic.  

And as the search never ends, I am now attempting to learn to delete the vnic.

You can use vna command to delete the vnic by simply passing the vnic 
link name to vna.
E.g. you can delete vnic0 by:
# /usr/lib/vna vnic0
