[Kimchi-devel] Problems with virsh iface-undefine or network.undefine()

[Aline Manera]

Hi Ramon,

I was checking the libvirt documentation and found that:

pydoc llibvirt.virInterface
  |  undefine(self)
  |      Undefine an interface, ie remove it from the config.
  |      This does not free the associated virInterfacePtr object.
  |
  |      Normally this change in the interface configuration is
  |      permanent/persistent, but if virInterfaceChangeBegin() has been
  |      previously called (i.e. if an interface config transaction is
  |      open), the removal of the interface definition will only become
  |      permanent if virInterfaceChangeCommit() is called prior to the next
  |      reboot of the system running libvirtd. Prior to that time, the
  |      definition can be explicitly restored using
  |      virInterfaceChangeRollback(), or will be automatically restored
  |      during the next reboot of the system running libvirtd.

Seems libvirt removes the network configuration file by default but you 
can change this behaviour as explained above.

Let me know if it works for you.

Regards,
Aline Manera
