Description of problem:
As subject

Version-Release number of selected component (if applicable):
libvirt-2.0.0-6.el7.x86_64
qemu-kvm-rhev-2.6.0-22.el7.x86_64


How reproducible:
100%

Steps to Reproduce:
1. Define VM n1 and n2 with following xml:
```
    <disk type='file' device='disk'>
      <driver name='qemu' type='qcow2' cache='none' io='native'/>
      <source file='/var/lib/libvirt/images/n1.qcow2'/>
      <target dev='vda' bus='virtio'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
    </disk>
```

2. Start n1 and n2
# virsh start n1                                                    
Domain n1 started

# virsh start n2                                                    
Domain n2 started

Then qemu will get SIGABRT.
