I had setup a testsystem with LXC and installed a webserver etc. that all was not the problem. But now I want to swich to another host system also I compressed /var/lib/lxc/webserver and copied it to the other host.But there i got serval errors:lxc-start: failed to attach 'vethO5HJ2b' to the bridge 'lxcbr0' : No such devicelxc-start: failed to create netdevlxc-start: failed to create the networklxc-start: failed to spawn 'webserver'In the config i did found settings for network. Any Ideas to fix the network issue or exits a better way to migrate between hosts ?ifconfig -a Host1 (VM is working here)eth0      Link encap:Ethernet  Hardware Adresse 00:25:90:d2:c2:d6            inet Adresse:85.xxx.xxx.43  Bcast:85.xxx.xxx.43  Maske:255.255.255.255          inet6-Adresse: fe80::225:90ff:fed2:c2d6/64 Gltigkeitsbereich:Verbindung          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metrik:1          RX packets:186831047 errors:0 dropped:0 overruns:0 frame:0          TX packets:170397357 errors:0 dropped:0 overruns:0 carrier:0          Kollisionen:0 Sendewarteschlangenlnge:1000           RX-Bytes:14641876568 (14.6 GB)  TX-Bytes:32363758586 (32.3 GB)          Speicher:f7100000-f7180000 eth0:1    Link encap:Ethernet  Hardware Adresse 00:25:90:d2:c2:d6            inet Adresse:81.xxx.xxx.247  Bcast:81.xxx.xxx.255  Maske:255.255.255.255          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metrik:1          Speicher:f7100000-f7180000 eth1      Link encap:Ethernet  Hardware Adresse 00:25:90:d2:c2:d7            BROADCAST MULTICAST  MTU:1500  Metrik:1          RX packets:0 errors:0 dropped:0 overruns:0 frame:0          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0          Kollisionen:0 Sendewarteschlangenlnge:1000           RX-Bytes:0 (0.0 B)  TX-Bytes:0 (0.0 B)          Interrupt:20 Speicher:f7200000-f7220000 lo        Link encap:Lokale Schleife            inet Adresse:127.0.0.1  Maske:255.0.0.0          inet6-Adresse: ::1/128 Gltigkeitsbereich:Maschine          UP LOOPBACK RUNNING  MTU:65536  Metrik:1          RX packets:22574 errors:0 dropped:0 overruns:0 frame:0          TX packets:22574 errors:0 dropped:0 overruns:0 carrier:0          Kollisionen:0 Sendewarteschlangenlnge:0           RX-Bytes:4393152 (4.3 MB)  TX-Bytes:4393152 (4.3 MB)lxcbr0    Link encap:Ethernet  Hardware Adresse ee:2c:00:bf:f0:a9            inet Adresse:10.0.3.1  Bcast:10.0.3.255  Maske:255.255.255.0          inet6-Adresse: fe80::ec2c:ff:febf:f0a9/64 Gltigkeitsbereich:Verbindung          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metrik:1          RX packets:0 errors:0 dropped:0 overruns:0 frame:0          TX packets:6 errors:0 dropped:0 overruns:0 carrier:0          Kollisionen:0 Sendewarteschlangenlnge:0           RX-Bytes:0 (0.0 B)  TX-Bytes:468 (468.0 B)bridge name bridge id       STP enabled interfaceslxcbr0      8000.000000000000   no  ls: Zugriff auf /var/log/upstart/lxc* nicht mglich: Datei oder Verzeichnis nicht gefunden (in English, not found)  $ brctl showbridge name bridge id       STP enabled interfaceslxcbr0      8000.000000000000   no      minecraft@h2210663:~$ ls -l /var/log/upstart/lxc*ls: Zugriff auf /var/log/upstart/lxc* nicht mglich: Datei oder Verzeichnis nicht gefundenminecraft@h2210663:~$ cat /etc/default/lxc# MIRROR to be used by ubuntu template at container creation:# Leaving it undefined is fine#MIRROR=http://archive.ubuntu.com/ubuntu# or #MIRROR=http://<host-ip-addr>:3142/archive.ubuntu.com/ubuntu# LXC_AUTO - whether or not to start containers symlinked under# /etc/lxc/autoLXC_AUTO=true# Leave USE_LXC_BRIDGE as true if you want to use lxcbr0 for your# containers.
