[ovirt-devel] Default MAC address range

Hi all, The default range went through several changes during the lifetime of the project - from being small and constant until 3.2, to small and random in 3.3 until 3.5, back to fixed and small in 3.6, slightly enlarged (to 1024 addresses) in current master. In all cases, the address range was taken from the IANA-assigned range 001A4A of Qumranet (now Red Hat) [1]. I suggest to: 1. Default to a random range again - So that two or (a few) more setups using the same network segment are less likely to use the same range 2. One in the locally-administered address range [2] - So that we have a larger address range 3. Make it a bit larger, say 65000 addresses - So that admins do not have to handle this manually, even for large setups, unless they have specific needs If there is objection to (2.), we can still have the others - among the 24 bits in the 001A4A prefix range, choose among the first 8 a random value during engine-setup, and have the pool of size 16 bits. Comments/ideas/etc. are welcome. Best regards, [1] https://regauth.standards.ieee.org/standards-ra-web/pub/view.html [2] https://en.wikipedia.org/wiki/MAC_address#Universal_vs._local -- Didi
