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>
"""
We can generate the mac and pass it to libvirt:
>> import virtinst.util
>> print virtinst.util.randomMAC()
00:16:3e:fd:b4:3a
I don't if libvirt requires a mac starting with "52:52:00"
Maybe it is used to avoid generating duplicated mac addresses.
