With the current tip: While extending a test case I found that attaching
and detaching the following network device works only 7 times with the
below script:

    <interface type='bridge'>
      <source bridge='static'/>
      <mac address='52:54:00:4d:a2:58'/>
      <target dev='attach0'/>

let c=1; while test 1; do virsh attach-device acl attach.xml ; virsh
detach-device acl attach.xml; echo ${c}; let c=c+1; done

Then the following error occurs:

error: Failed to attach device from attach.xml
error: operation failed: parsing pci_add reply failed: Too Many NICs
failed to add macaddr=52:54:00:4d:a2:58,vlan=1,name=net1

It looks like the detachment of the device is not done by qemu?
