[Pkg-libvirt-maintainers] Bug#514803: libvirt-bin: "virsh net-create /etc/libvirt/qemu/networks/default.xml" allows to start the VM

[Laurent Vivier]

Package: libvirt-bin
Version: 0.4.6-10
Followup-For: Bug #514803


This bug is found using virt-manager.

The VM has been created and run without problem the first time.
After a reboot of the host, when I try to start the VM the problem 
appears.

My VM is defined by:

<domain type='kvm'>
  <name>debian-i386</name>
  <uuid>a8c92ab9-870d-3965-3ab4-5100d43ff5e4</uuid>

      <target port='0'/>
    </serial>
    <console type='pty' tty='/dev/pts/3'>

    <input type='mouse' bus='ps2'/>

  </devices>
</domain>

virt-manager.log:

If I run:
$ sudo virsh net-create /etc/libvirt/qemu/networks/default.xml
Network default created from /etc/libvirt/qemu/networks/default.xml

The VM can be started without problem.
