Hi, I am running many BHyve VM's and am using tap interfaces with a single bridge. I am configuring the IP addresses of these VM's via DHCP. I need to have separate MAC addresses for each VM. Can anyone recommend a range of MAC addresses to use? I seem to recall that at the 2013 FreeBSD Vendor Summit in Sunnyvale, California, that George mentioned that there might be a Organizational Unique Identifier (OUI) for the FreeBSD project that we can use for BHyve VM's. Is that right? If not, can people recommend a range of addresses to use? VMWare for example has an OUI of 00:50:56 ( http://pubs.vmware.com/vsphere-4-esxi-installable-vcenter/index.jsp?topic=/com.vmware.vsphere.esxi_server_config.doc_41/esx_server_config/advanced_networking/c_setting_up_mac_addresses.html) I'd rather not use that range if I don't have to, since I have a VMWare ESXi server running in the same network. :) -- Craig
