Verified as Passed in below environment:
# uname -a
Linux dhcp-65-85.nay.redhat.com 2.6.32-112.el6.x86_64 #1 SMP Wed Feb 2 14:17:15 EST 2011 x86_64 x86_64 x86_64 GNU/Linux
kernel-2.6.32-112.el6.x86_64
qemu-kvm-0.12.1.2-2.132.el6.x86_64
libvirt-0.8.7-6.el6.x86_64

Steps:
1. Make sure the guest is in running
# virsh start rhel6
Domain rhel6 started

# virsh dumpxml rhel6 |grep network
    <interface type='network'>
      <source network='default'/>

2. Attach the interface
# virsh attach-interface rhel6 network default
Interface attached successfully

# virsh dumpxml rhel6 
...
    <interface type='network'>
      <mac address='52:54:00:5f:c1:6f'/>
      <source network='default'/>
      <target dev='vnet1'/>
      <alias name='net0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/>
    </interface>
    <interface type='network'>
      <mac address='52:54:00:e5:9a:52'/>
      <source network='default'/>
      <target dev='vnet2'/>
      <alias name='net1'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
    </interface>
...

3. In guest, check this network interface (mac 52:54:00:e5:9a:52) can get ip and ping successfully
