Public bug reported: i have a server (Proliant DL380 gen9). it has 4 Ethernet ports eno1 thru eno4. i am using ubuntu 17.10 and KVM with 4 multiple guest VMs. under Ubuntu 17.04 i had this in my /etc/network/interfaces:
auto virbr0 iface virbr0 inet dhcp bridge_ports eno1 bridge_stp off bridge_fd 0 bridge_maxwait 0 So i did not define eno2 thru eno4 and everything worked fine. After i upgraded to Ubuntu 17.10, i suddenly started having IP conflict from the DHCP server. after a lot of search, i figured my problem may be from the eno2-4 are getting IP even though they are dedicated to VMs. so i defined them as manual in /etc/network/interfaces as such: # Ethernet port for cad-srvr VM auto eno2 iface eno2 inet manual up ifconfig eno2 up # Ethernet port for nxtcld-srvr VM auto eno3 iface eno3 inet manual up ifconfig eno3 up # Ethernet port for Future-srvr VM auto eno4 iface eno4 inet manual up ifconfig eno4 up This caused the DHCP warnings of conflicted IP to disappear. I am not sure if this is per design or not... please advice me if i need to provide any other info ** Affects: apparmor (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apparmor in Ubuntu. https://bugs.launchpad.net/bugs/1741331 Title: Ethernet interface aquire IP even if not defined in /etc/network/interfaces Status in apparmor package in Ubuntu: New Bug description: i have a server (Proliant DL380 gen9). it has 4 Ethernet ports eno1 thru eno4. i am using ubuntu 17.10 and KVM with 4 multiple guest VMs. under Ubuntu 17.04 i had this in my /etc/network/interfaces: auto virbr0 iface virbr0 inet dhcp bridge_ports eno1 bridge_stp off bridge_fd 0 bridge_maxwait 0 So i did not define eno2 thru eno4 and everything worked fine.
