Hallo everyone,
I just installed last versione of PVS (4.2), and did an apt-get update/upgrade.
I created a test CT using Ubuntu 14.04 template downloaded from the web interface.
I did a setup of the new CT (100) using following network configuration

upload_2016-7-8_15-46-9.png

When I boot the CT 100 I receive an error message.
I tried from command line and set the debug level as follow:
# lxc-start -n 100 --logfile /tmp/errore --logpriority DEBUG -F

This is the error message i receive on stdout

# lxc-start -n 100 --logfile /tmp/errore --logpriority DEBUG -F
bridge 'vmbr0' does not exist
lxc-start: conf.c: run_buffer: 342 Script exited with status 2
lxc-start: conf.c: lxc_create_network: 3084 failed to create netdev
lxc-start: start.c: lxc_spawn: 954 failed to create the network
lxc-start: start.c: __lxc_start: 1211 failed to spawn '100'
lxc-start: lxc_start.c: main: 344 The container failed to start.
lxc-start: lxc_start.c: main: 348 Additional information can be obtained by setting the --logfile and --logpriority options.
#

and you can see the full log file:

I just fixed the network broblem.
I noticed that interface vmbr0 was not in the output of ifconfig command (I imported the /etc/network/interfaces from a workin VE3.3 installation as a template) so I used the graph interface to delete and create the vmbr0 interface.
After that the vmbr0 and associated vlans are now appearing in ifconfig

Just for reference the problem was the word static in /etc/network/interfaces file, that must be manual

- iface vmbr0 inet static
+ iface vmbr0 inet manual

Again the new created CT100 won't start for a different reason now

And follow the logfile content, seems due to a missing apparmor profile....
