Hi,

After inserting the xen backend, if I want to use vale bridge create the vm, I met this error:

zhangwei1984@nimbnode21:~/clickos/clickvms$ sudo xl create vm1.cfg
Parsing config from vm1.cfg
libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: /etc/xen/scripts/vif-vale online [24793] exited with error status 1

vm configuration file

zhangwei1984@nimbnode21:~/clickos/clickvms$ cat vm1.cfg 
name   = 'vm1'
kernel = '/home/zhangwei1984/clickos/clickvms/vm1'
vcpus  = '1'
# pinning your VCPU helps performance
#cpus   = '3'
memory = '8'
vif    = ['bridge=vale0,script=vif-vale']
on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'preserve'                        
click       = 'mirror.click'

I can create vale bridge and attach a port. The following info shows that

zhangwei1984@nimbnode21:~/clickos/clickvms$ sudo /home/zhangwei1984/clickos/xennet/netmap/examples/vale-ctl -l zhangwei1984@nimbnode21:~/clickos/clickvms$ sudo /home/zhangwei1984/clickos/xennet/netmap/examples/vale-ctl -a vale0:p2p2
zhangwei1984@nimbnode21:~/clickos/clickvms$ sudo /home/zhangwei1984/clickos/xennet/netmap/examples/vale-ctl -l bdg_ctl [98] bridge:0 port:0 vale0:p2p2

solved. By adding the path environment in bashrc, it does not work. Have to hardcoded to the script.
