Re: [Kimchi-devel] [RFC]: help, how to get the mac after create a VM interface.
libvirt always adds the new interface to the end of the group. I did a
little experimenting to make sure. So, you could just parse the
interfaces and pull the MAC from the last one returned. It's not very
elegant, though.

when I create a interface, There is no mac attribute in the xml.
After create successfully, libvirt will allocate a mac.
The problem is that, How can I get the mac.
Should the CREATE method always needs to return an interface info?
Here is some of create code.
def vmifaces_create(self, vm, params):
dom = self._get_vm(vm)
xml = """
<interface type='network'>
<source network='default'/>
</interface>
"""
dom.attachDeviceFlags(xml,
libvirt.VIR_DOMAIN_AFFECT_CURRENT)
# here I need to return the mac
return ????
The libvirt will create a xml like the follow? The problem is that the a
vm may have several interfaces.
xml = """
<interface type='network'>
<mac address='52:54:00:2a:53:8f'/>
<source network='default'/>
<model type='rtl8139'/>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03' function='0x0'/>
</interface>
"""
