If anyone has experienced this problem on Hardy, please chime in here. I had a patch at https://launchpad.net/~serge-hallyn/+archive/libvirt-fix-macaddr?field.series_filter=hardy which can be forward-ported if need be, but I've not heard anyone mention having this bug on Hardy, so don't want to rock the boat needlessly. -- libvirt should not use the MAC address assigned to tap devices/vnet interfaces by the TAP/TUN driver https://bugs.launchpad.net/bugs/579892 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This is my network configuration: auto br0 iface br0 inet dhcp bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off pre-up ifconfig eth0 hw ether 00:00:00:00:00:01 The macaddress change is the workaround I'm using right now so I'm able to avoid this issue. The libvirt network configuration is disabled on this server, because I'm using the main bridge and I don't want it to do NAT. ** Attachment added: Machine XML file http://launchpadlibrarian.net/48736588/paris.xml ** Changed in: libvirt (Ubuntu) Status: Incomplete = New -- libvirt should not use the MAC address assigned to tap devices/vnet interfaces by the TAP/TUN driver https://bugs.launchpad.net/bugs/579892 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
