Hello LXC experts,
I meet a problem. When using vlan as network device in suse11 system container,
I can not use halt to stop this container. It hung on "eth0 is still used from interfaces eth0" in cycle.
The config file:
lxc.network.type = vlan
lxc.network.flags = up
lxc.network.link = eth0
lxc.network.name = eth0
lxc.network.vlan.id = 1301
lxc.network.ipv4 = 128.5.131.100/24
The reason is in the shell command /sbin/ifdown, see below:
######################################################################
# Shut down depending interfaces
#
# Check if there are interfaces which depend on this interface. If yes these
# have to be shut down first.
# For example these might be bonding or vlan interfaces. Note that we don't
# catch all types of depending interfaces currently. See function
# 'get_depending_ifaces' in file 'functions' for details.
#
test "$SCRIPTNAME" = ifdown && DEP_IFACES=`get_depending_ifaces $INTERFACE`
if [ "$?" = 0 -a "$NODEPS" != yes ] ; then
message "`printf " %-9s is still used from interfaces %s" \
$INTERFACE "$DEP_IFACES"`"
for DI in $DEP_IFACES; do
ifdown $DI -o $OPTIONS
done
message "`printf " %-9s now going down itself" $INTERFACE`"
# check if iface is (still) avaliable
# [bonding master may go down itself
# while the last slave gets removed]
if ! is_iface_available $INTERFACE; then
exit $R_SUCCESS
fi
fi
$DEP_IFACES is also eth0 in this scene, so ifdown will call ifdown again and again.
if we set lxc.network.name = eth1, it will be ok, so can we add a judgment to make
lxc.network.link and lxc.network.name are not equal in lxc-start command.
simple implement like:
if [ lxc.network.type == vlan ] ; then
if [ lxc.network.link == lxc.network.name ] ; then
return false
fi
fi
Is it reasonable? or any other way to achieve this?
