[Lxc-users] many veth interfaces hanging around postmortem

[C Anthony Risinger]

i'm not sure exactly how to reproduce this or whats happening, but while
using my tools (vps-lxc) to test/generate container configs i notice that
over time i get several stagnant veth interfaces that seem to not be cleaned
up properly.  this is what i have running:

$ vps-lxc ls dom
dom   guest-private-cr                RUNNING
dom   guest-private-mk              RUNNING
dom   guest-service-http_proxy   RUNNING
dom   host-service-email            RUNNING

(that command basically just loops thru the domains and does an lxc-info on
each one)  i only have 4 domains running/defined, three of them have 2
interfaces, and the 4th only has one, so 7 interfaces total.  however in my
brctl:

$ brctl show
bridge name     bridge id               STP enabled     interfaces
br0             8000.000bdb92cf22       no              eth0
                                                        vethrWDKp9
                                                        vethw5rA8d
                                                        vethKg5sKA
                                                        vethiUXbg9
                                                        veth6UWnZz
                                                        vethcQzgNh
                                                        vetha7wyPO
dhcpbr0         8000.06452378c895       no              veth0oGNFm
                                                        vethagpIpC
                                                        vethTx7AAO
                                                        vethLh2bHE
                                                        veth2ctG5A
                                                        vethqI1MjQ
                                                        vethAad9n1
                                                        veth2CPXrC

there are 15 veth interfaces still up.  if i do an ifconfig i also see 15
veth interfaces up.  if i do an "ifconfig -a" i see 23 veth interfaces up
and down?  i'm using BTRFS so i've been generating templates like crazy, 1-x
hundred, so i'm really not sure when or why it's happening at this point.
 seems like the veth interface is not being removed from the bridge and thus
can't be removed completely?  might be me, but seems like a bug; is anyone
else noticing behavior like this?

thanks
