Hi Geoff,

Thanks for prompt reply.  I have assigned correct interface. Please see below for more detail,

[root@localhost rules.d]# brctl show

bridge name     bridge id               STP enabled     interfaces

eth0            8000.001c2596e32b       no              peth0

pan0            8000.000000000000       no

virbr0          8000.000000000000       yes


[root@localhost xen]# cat test|grep -i vif
vif = [ 'type=ioemu, bridge=eth0' ]

root@localhost xen]# xm create test
Using config file "./test".
Error: Device 0 (vif) could not be connected. Hotplug scripts not working.


Looking the xend.log, I can see that, vif  virtual interface device is created and  for status it is waiting in dom0(backend side) for hotplug callback status of device... for more details see below full xend.log,  I have highlighted vif log details in red color just for better visibility... Please guide me through my installation.
