[libvirt] KVM root mac address
A quick question - What is the correct root for dynamically generated KVM mac addresses? The docs (man virt-install) say 54:52:00 and I've seen Ubuntu docs on-line that say 52:54:00. Has someone got these mixed up? Thanks Paul -- Paul Reeves

Does no one know? Is this the wrong list? Paul -- Paul Reeves

Yes it is. Try www.linux-kvm.org and search for a list there. This list here is for libvirt.

THe source code always wins macaddr[0] = 0x52; macaddr[1] = 0x54; macaddr[2] = 0x00; macaddr[3] = 0x12; macaddr[4] = 0x34; macaddr[5] = 0x56 + idx; So 52:54:00 is the correct prefix Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

So 52:54:00 is the correct prefix
