Hi all:

I can start domU manually; however, I can't automatically start domU by putting 
the domU name in xendomains variable in /etc/rc.conf. I think the problem is 
with associating vif with bridge. I've put the required info below and greatly 
appreciate any help to resolve this issue. Let me know if more info is needed.

Thanks,
Kalpesh

/etc/rc.conf file snippet:
. . .
xenbackendd=YES
xend=YES
xendomains="nbsd03"

On dom0 console I get following (I had to note down the error manually as 
copy-paste was not possible for this)

Xbd backend attach device vnd0d for domain1 Failed to read 
/local/domain/0/backend/console/1/0/script (no such file or directory)

Error: device 0(vif) could not be connected. Hotplug scripts not working.

DomU Config File:
#  -*- mode: python; -*-
kernel = "/netbsd-XEN3_DOMU"
memory = 160

ip = "10.11.204.184"

gateway = "10.11.204.254"
vif = [ 'bridge=bridge1' ]
disk = [ 'file:/dsk/nbsd03/nbsd03.img,0x01,w' ]

bridge1 is created and below is the ifconfig output for it.
