Editing Disable venet interface

If you have configured [[veth]] correctly and want to get rid of [[venet]] interface modify ''/etc/init.d/vz'' following this step:

'''Note: In Debian systems (Ubuntu and more) for disable venet interface it's enough with the next second step'''(Comment line ''VZDEV=venet0'' (~ line 53).).'''
'''Don't forget edit (in Debian example) /etc/network/interface file in (/var/lib/vz/private/$VEID/ and remove venet configuration in that file'''


1. /etc/init.d/vz stop before going further.

2. Comment line ''VZDEV=venet0'' (~ line 53).

3. Replace line ''NET_MODULES="${VNET_MODULES} ${VETH_MODULES}"'' (~ line 67) with this block:

<code>
        ####################################
        # Patch for disable venet interface
        # Block 1
        # 2009-10-29 Michael Plourde
        ###################################
        NET_MODULES="${VETH_MODULES}"
        if [ -n "${VZDEV}" ]
        then
                NET_MODULES="${NET_MODULES} ${VNET_MODULES}"
        fi
        ####################################
        #  Patch for disable venet interface
        #  End Block 1
        #  2009-10-29 Michael Plourde
        ###################################
</code>

4. In the start_net() function (~ line 306) find those lines:
<code>
                __echo "Bringing up interface $VZDEV: "
                ip link set $VZDEV up
                print_result
                ip addr add 0.0.0.0/0 dev $VZDEV
                __echo "Configuring interface $VZDEV: "
                sysctl -q -w net.ipv4.conf.$VZDEV.send_redirects=0
                print_result
                if [ "${IPV6}" = "yes" ]; then
                        __echo "Configuring ipv6 $VZDEV: "
                        # Fix me: ip addres should be generated
                        ip -6 addr add fe80::1/128 dev $VZDEV
                        print_result
                fi
</code>

and add these block before:
<code>
        ####################################
        # Patch for disable venet interface
        # Block 2
        # 2009-10-29 Michael Plourde
        ###################################
        if [ -n "$VZDEV" ]
        then
</code>
and this one after:
<code>
        fi
        ####################################
        # Patch for disable venet interface
        # End Block 2
        # 2009-10-29 Michael Plourde
        ###################################
</code>

The start_net function should look like this:
<source lang="bash">
start_net()
{
        local mod

        # load all kernel modules needed for VE networking
        for mod in ${NET_MODULES}; do
                modprobe ${mod} 2>/dev/null
        done

        if ip addr list | grep -q "venet0:.*UP" 2>/dev/null; then
                return 0
        fi

        get_veinfo
        if [ -z "$VEINFO" ]; then
                return 0
        fi
        ####################################
        # Patch for disable venet interface
        # Block 2
        # 2009-10-29 Michael Plourde
        ###################################
        if [ -n "$VZDEV" ]
        then
                __echo "Bringing up interface $VZDEV: "
                ip link set $VZDEV up
                print_result
                ip addr add 0.0.0.0/0 dev $VZDEV
                __echo "Configuring interface $VZDEV: "
                sysctl -q -w net.ipv4.conf.$VZDEV.send_redirects=0
                print_result
                if [ "${IPV6}" = "yes" ]; then
                        __echo "Configuring ipv6 $VZDEV: "
                        # Fix me: ip addres should be generated
                        ip -6 addr add fe80::1/128 dev $VZDEV
                        print_result
                fi
        fi
        ####################################
        # Patch for disable venet interface
        # End Block 2
        # 2009-10-29 Michael Plourde
        ###################################
}</source>

5. Modify the stop_net function (~ line 351) to look like this:

<source lang="bash">
stop_net()
{
        local mod
        ####################################
        # Patch for disable venet interface
        # Block 3
        # 2009-10-29 Michael Plourde
        ###################################
        if [ -n "$VZDEV" ]
        then
                if ip addr list | grep -q "venet0:.*UP" 2>/dev/null; then
                        __echo "Bringing down interface $VZDEV: "
                        ip link set $VZDEV down
                        print_result
                fi
        fi
        ####################################
        # Patch for disable venet interface
        # End Block 3
        # 2009-10-29 Michael Plourde
        ###################################
        for mod in ${NET_MODULES}; do
                /sbin/modprobe -r ${mod} > /dev/null 2>&1
        done
}</source>

6. That's all. You can now start your VEs:''/etc/init.d/vz start''
