Re: [ovirt-users] vlan-tagging on non-tagged network

Hi, My two cents is that shouldn’t be doing mac spoofing protection as a default. There are several use cases where you may use virtual nics defined withing the guest and this feature is going to create problems to users that may not know that there’s a mac spoofing protection withing ovirt. Think of keeaplived vmac option, openvpn and any tap adapter you need to create. If you need to protect against spoofing attacks, you should use the hook or more powerful tools and in any case, you must be aware that you used this kind of protection. Regards,

I disagree: This violates the "secure by default" design pattern. The default should be secure, furthermore, it was so in every ovirt release before, so it would be a sudden change. if you need such advanced network setups in your guests you should be able to search the documentation. - -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
