I have a question about Network Interfaces in LXC container:In my container,I have by default these interfaces:ubuntu@u5:~$ ifconfigeth0      Link encap:Ethernet  HWaddr 00:16:3e:b7:de:91           inet addr:10.0.3.138  Bcast:10.0.3.255  Mask:255.255.255.0          inet6 addr: fe80::216:3eff:feb7:de91/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:56 errors:0 dropped:0 overruns:0 frame:0          TX packets:40 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000          RX bytes:7230 (7.2 KB)  TX bytes:3500 (3.5 KB)       lo        Link encap:Local Loopback                  inet addr:127.0.0.1  Mask:255.0.0.0                 inet6 addr: ::1/128 Scope:Host                 UP LOOPBACK RUNNING  MTU:65536  Metric:1                 RX packets:0 errors:0 dropped:0 overruns:0 frame:0                 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0                 collisions:0 txqueuelen:0                 RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)I'd like to add this new interface:      auto eth1      iface eth1 inet static      address 192.168.1.3      netmask 255.255.255.0      network 192.168.1.1      broadcast 192.168.1.255So,I have modified this file: /etc/network/interfaces     # This file describes the network interfaces available on your system     # and how to activate them. For more information, see interfaces(5).     # The loopback network interface     auto lo     iface lo inet loopback     auto eth0     iface eth0 inet dhcp     auto eth1     iface eth1 inet static     address 192.168.1.3     netmask 255.255.255.0     network 192.168.1.1     broadcast 192.168.1.255I have done reboot but it didn't work ! when I  use ifconfig, I  cant' find the new interface:      ubuntu@u5:/etc/network$ ifconfig      eth0      Link encap:Ethernet  HWaddr 00:16:3e:b7:de:91                 inet addr:10.0.3.138  Bcast:10.0.3.255  Mask:255.255.255.0                inet6 addr: fe80::216:3eff:feb7:de91/64 Scope:Link                UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1                RX packets:57 errors:0 dropped:0 overruns:0 frame:0                TX packets:40 errors:0 dropped:0 overruns:0 carrier:0                collisions:0 txqueuelen:1000                RX bytes:7337 (7.3 KB)  TX bytes:3500 (3.5 KB)       lo        Link encap:Local Loopback                  inet addr:127.0.0.1  Mask:255.0.0.0                 inet6 addr: ::1/128 Scope:Host                 UP LOOPBACK RUNNING  MTU:65536  Metric:1                 RX packets:0 errors:0 dropped:0 overruns:0 frame:0                 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0                 collisions:0 txqueuelen:0                 RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)Have you an idea please ?
