Public bug reported:
I am using Ubuntu 13.04 with latest update and the package LXC to run
some virtual machines in it.
I am using the following parameter for one of the machines:
--------- CONFIG ------------
lxc.network.type=veth
lxc.network.link=br0
lxc.network.flags=up
lxc.network.hwaddr = 10:16:3e:53:5b:7a
lxc.network.veth.pair = veth_jenkins
lxc.network.ipv4 = 192.168.1.30/24
#lxc.network.ipv6 = 2003:db8:1:0:214:1234:fe0b:3597
lxc.rootfs = /var/lib/lxc/jenkins/rootfs
lxc.utsname = jenkins
lxc.devttydir = lxc
lxc.tty = 4
lxc.pts = 1024
lxc.mount = /var/lib/lxc/jenkins/fstab
lxc.arch = amd64
lxc.cap.drop = sys_module mac_admin mac_override
lxc.pivotdir = lxc_putold
# uncomment the next line to run the container unconfined:
#lxc.aa_profile = unconfined
lxc.cgroup.devices.deny = a
# Allow any mknod (but not using the node)
lxc.cgroup.devices.allow = c *:* m
lxc.cgroup.devices.allow = b *:* m
# /dev/null and zero
lxc.cgroup.devices.allow = c 1:3 rwm
lxc.cgroup.devices.allow = c 1:5 rwm
# consoles
lxc.cgroup.devices.allow = c 5:1 rwm
lxc.cgroup.devices.allow = c 5:0 rwm
#lxc.cgroup.devices.allow = c 4:0 rwm
#lxc.cgroup.devices.allow = c 4:1 rwm
# /dev/{,u}random
lxc.cgroup.devices.allow = c 1:9 rwm
lxc.cgroup.devices.allow = c 1:8 rwm
lxc.cgroup.devices.allow = c 136:* rwm
lxc.cgroup.devices.allow = c 5:2 rwm
# rtc
lxc.cgroup.devices.allow = c 254:0 rwm
#fuse
lxc.cgroup.devices.allow = c 10:229 rwm
#tun
lxc.cgroup.devices.allow = c 10:200 rwm
#full
lxc.cgroup.devices.allow = c 1:7 rwm
#hpet
lxc.cgroup.devices.allow = c 10:228 rwm
#kvm
lxc.cgroup.devices.allow = c 10:232 rwm
lxc.cgroup.memory.limit_in_bytes = 8G
lxc.cgroup.memory.soft_limit_in_bytes = 2G
lxc.cgroup.cpuset.cpus = 0-3
--------- /CONFIG ------------
When I start this LXC container, the network will be started as expected as you
can see in the ifconfig output:
veth_jenkins Link encap:Ethernet HWaddr fe:31:67:cb:ef:25
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:145 errors:0 dropped:0 overruns:0 frame:0
TX packets:350 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:25708 (25.7 KB) TX bytes:59185 (59.1 KB)
The issue I have is the following: when I shutdown the LXC container, the
"veth_jenkins" interface stays active and will not teared down with the
machine. This is not so nice, but it is really ugly, if you try to start the
machine again, because then it will not start anymore, because it says, that
the interface name is not unique...of course not, but I would like to not use
random name, because I like to be able to identify the related interfaces.
