create device by command
ip tuntap add dev privnet0 mode tap one_queue vnet_hdr

set it in guest xml by

<interface type='network'>
      <mac address='52:54:00:e8:6d:19'/>
      <source network='testnet'/>
      <target dev='privnet0'/>
      <model type='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03'
function='0x0'/>
    </interface>


testnet is

<network>
  <name>testnet</name>
  <uuid>f31d8d1b-9ff4-8bf7-d8b6-e6bd8759a2f1</uuid>
  <forward mode='bridge'/>
  <bridge name='br0' />
</network>


guest start, privnet0 added to bridge br0 and set up.
work fine.
after guest is shutdown privnet0 is not removed from bridge br0 and
guest not started after.
What is wrong?
