lxc-net 不喜歡橋接容器的靜態 ip

我剛剛開始使用 LXC 容器，我發現即使我在 lxc 容器配置文件上設置了一個特定的 IP 地址，lxc-ls --fancy也總是顯示另一個 IP，它是可 ping 的，並且/etc/network/interfaces設置不會覆蓋lxc-net設置。

我正在使用lxc2.0.7。

容器配置：

lxc.network.type = veth
lxc.network.hwaddr = 00:1a:b2:ff:62:32
lxc.network.link = lxcbr0
lxc.network.ipv4 = 10.0.3.2/24
lxc.network.ipv4.gateway = 10.0.3.1
lxc.network.flags = up

lxc.rootfs = /var/lib/lxc/debcontainer/rootfs
lxc.rootfs.backend = dir

# Common configuration
lxc.include = /usr/share/lxc/config/debian.common.conf

# Container specific configuration
lxc.tty = 4
lxc.utsname = debcontainer
lxc.arch = amd64

介面配置：

auto eth0

iface eth0 inet static
address 10.0.3.3
netmask 255.255.255.0
gateway 10.0.3.1

主機介面：

eth0      Link encap:Ethernet  HWaddr XX:XX:XX:XX:XX:XX
         ...

lo        Link encap:Local Loopback
         ...

         RX bytes:18559 (18.1 KiB)  TX bytes:19428 (18.9 KiB)

容器配置：

eth0      Link encap:Ethernet  HWaddr 00:1a:b2:ff:62:32  
         inet addr:10.0.3.2  Bcast:255.255.255.255  Mask:255.255.255.255
         inet6 addr: fe80::216:abff:fec4:63ff/64 Scope:Link

         RX bytes:20061 (19.5 KiB)  TX bytes:20259 (19.7 KiB)

lo        Link encap:Local Loopback
         ...

lxc-fs輸出：

user@debian-8-test:~$ sudo lxc-ls --fancy
NAME         STATE   AUTOSTART GROUPS IPV4                 IPV6 
debcontainer RUNNING 0         -      10.0.3.2, 10.0.3.211 -

解決方案

編輯 /etc/default/lxc-net 並註釋或刪除 LXC 網橋名稱（如果指定）和 dhcp 選項：

USE_LXC_BRIDGE="true"
#LXC_BRIDGE="lxcbr0"
LXC_ADDR="10.0.3.1"
LXC_NETMASK="255.255.255.0"
LXC_NETWORK="10.0.3.0/24"
#LXC_DHCP_RANGE="10.0.3.2,10.0.3.254"
#LXC_DHCP_MAX="253"
#LXC_DHCP_CONFILE=""
LXC_DOMAIN=""

編輯/etc/network/interfaces和設置靜態配置：

auto eth0
iface eth0 inet static
   address 10.0.3.3
   gateway 10.0.3.1
   netmask 255.255.255.0

或者

設置網路配置<container>/config：

lxc.network.type = veth
lxc.network.hwaddr = 00:1a:b2:ff:62:32
lxc.network.link = lxcbr0
lxc.network.ipv4 = 10.0.3.2/24
lxc.network.ipv4.gateway = 10.0.3.1
lxc.network.flags = up

並設置手動界面配置/etc/network/interfaces：

auto eth0
iface eth0 inet manual
