device added but no graph

i have installed cacti on a debian machine version 6.0.7
everything is working great localhost graphs are fine.

actually i have another virtualization server on Debian and i want it to
monitor with cacti however the good thing is i can create a device and so
far log shows i can successfully add the device, even i can create graphs
as per the status says graph created. but in graph tab i can conly see
localhost. no new devise has been showed up in that tab.
here is the detail of my device when i add one

Basehost (10.xx.xx.13) SNMP Information
 *System:*Linux virt-dev 2.6.32-19-pve #1 SMP Wed May 15 07:32:52 CEST 2013
x86_64
*Uptime:* 404058 (0 days, 1 hours, 7 minutes)
*Hostname:* virt-dev
*Location:* Sitting on the Dock of the Bay
*Contact:* Me [email protected]

here is the device tab snap which shows that device is successfully
connected and up


i see no logs in cacti log file except this line
