You need to add the physical interface (say eth0)  to the bridge.

This setup is done when u run convirt-tool on the managed server.
If you have started doing this manually.. then make sure that ifcfg-eth0 has BRIDGE=br0.

If you still run in to problem.
Send in output of brctl show when the VM is running.

"nic,vlan=0,macaddr=00:16:3e:2f:e2:5f" -net
"tap,vlan=0,script=/etc/kvm/qemu-ifup-br0" -append
"/home/yash/iso/mount/images/pxeboot/vmlinuz" -usb "1" -boot "c" -m
