Hi all. I use LXC on Centos 7 x86-64, with libvirt version 1.2.6 and 1.2.12 My container has bridged network: # virsh dumpxml test1 <domain type='lxc'> <name>test1</name> <uuid>518539ab-7491-45ab-bb1d-3d7f11bfb0b1</uuid> <memory unit='KiB'>1048576</memory> <currentMemory unit='KiB'>1048576</currentMemory> <memtune> <hard_limit unit='KiB'>1048576</hard_limit> <soft_limit unit='KiB'>1048576</soft_limit> <swap_hard_limit unit='KiB'>2097152</swap_hard_limit> </memtune> <vcpu placement='static'>2</vcpu> <os> <type arch='x86_64'>exe</type> <init>/sbin/init</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='block' accessmode='passthrough'> <source dev='/dev/data/test1'/> <target dir='/'/> </filesystem> <filesystem type='ram' accessmode='passthrough'> <source usage='524288' units='KiB'/> <target dir='/dev/shm'/> </filesystem> <interface type='direct'> <mac address='02:00:00:1a:a9:54'/> <source dev='br0' mode='bridge'/> </interface> <console type='pty'> <target type='lxc' port='0'/> </console> </devices> </domain> And all was fine, before I accidentally upgraded Centos to 7.1.1503 After upgrade LXC can't start with diagnostic: [root@node14 ~]# virsh start test1 error: Failed to start domain test1 error: internal error: guest failed to start: internal error: Child process (ip link set macvlan0 netns 25263) unexpected exit status 2: RTNETLINK answers: Invalid argument I reinstall libvirt 1.2.14, but catch same error. If someone will experience in solving this problem - it will be interesting to hear about. b.r.
