Re: [Users] disable EnableMACAntiSpoofingFilterRules per VM
Resending cause somehow the format got screwed up.

The default is to filter. You'll have to add a VM or VNIC custom property
and set the value to False whenever you want to disable the filtering.

You would think that anything VNIC specific would take precedence, but with
how the code is implemented at this time, before_device_create is called
for all devices, and before_vm_create is called after that. That means
that whatever is defined at the VM level will take precedence.
ok, this worked like a charm but I did some changes.
Maybe you want to update the README on
https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/macspoof/README
engine-config -s
UserDefinedVMProperties='previousPropertiesmacspoof=^(true|false)$'
--cver=3.3
failed with an error:
Cannot set value previousProperties;macspoof=^(true|false)$ to key
UserDefinedVMProperties. Invalid syntax, user defined VM properties
specification should conform to
(([a-z_A-Z0-9])+)=(([^;])+)(;(([a-z_A-Z0-9])+)=(([^;])+))*;?
I changed that to
engine-config -s "UserDefinedVMProperties=macspoof=(true|false)"
like it is defined in http://www.ovirt.org/Engine_config_examples
which was inserted with no error.
CustomDeviceProperties also inserted like
engine-config -s CustomDeviceProperties=
'{type=interface;prop={ifacemacspoof=(true|false)}}'
so both true/false options could be available.
VM option indeed takes precedence over VNIC option.
You should also take notice that setting macspoof=false or
ifacemacspoof=false does the opposite of at least what I expected.
It filters.
I had to apply with either macspoof=true or ifacemacspoof=true to
disable filtering.
The README also has that the other way.
Either the README has to be changed or the options could be renamed to
something like disable_macspoof_filter and disable_ifacemacspoof_filter
