Hello,

Hi,

1. Please show how do you exactly create eth* interfaces per VE. (the exact command - "vzctl set --netif_add ...")

NETIF in all XXX.conf where XXX = VEID

NETIF="ifname=eth1.32,mac=00:16:3E:0X:XX:1E,host_ifname=vethXXX.32,host_mac=FE:FF:FF:FF:FF:FF;ifname=eth1.35,mac=00:16:3E:0X:XX:1E,host_ifname=vethXXX.35,host_mac=FE:FF:FF:FF:FF:FF;ifname=eth1.36,mac=00:16:3E:0X:XX:1E,host_ifname=vethXXX.36,host_mac=FE:FF:FF:FF:FF:FF"

/etc/vz/vznet.conf :

#!/bin/bash
EXTERNAL_SCRIPT="/usr/sbin/vznetaddroute

here the script that create the interface inside the HN

#!/bin/bash
# /usr/sbin/vznetaddroute
# a script to bring up virtual network interfaces (veth's) in a VE
CONFIGFILE=/etc/vz/conf/$VEID.conf
. $CONFIGFILE
VETH=$3
VZHOSTIF=`echo ${VETH} | cut -f1 -d"."`
VLAN=`echo ${VETH} | cut -f2 -sd"."`

if [ -n "${VLAN}" ] ; then
        VETH_BRIDGE=brvlan${VLAN}

        if [ ! -n "${VZHOSTIF}.${VLAN}" ]; then
                echo "According to $CONFIGFILE VE$VEID has no veth interface configured."
                exit 1
        fi

        if [ ! -n "${VETH_BRIDGE}" ]; then
           echo "According to $CONFIGFILE VE$VEID has no veth VETH_BRIDGE configured."
           exit 1
        fi

        echo "Adding interface ${VZHOSTIF}.${VLAN} to VETH_BRIDGE ${VETH_BRIDGE} on VE0"

        if [ -z "`/usr/sbin/brctl show | /bin/grep ${VETH_BRIDGE}`" ]; then
           /usr/sbin/brctl addbr ${VETH_BRIDGE}
           /usr/sbin/brctl addif ${VETH_BRIDGE} eth1.${VLAN}
           /sbin/ip link set ${VETH_BRIDGE} up
        fi

        /usr/sbin/brctl addif ${VETH_BRIDGE} ${VZHOSTIF}.${VLAN}
        /sbin/ip link set ${VZHOSTIF}.${VLAN} up
else
        VETH_BRIDGE=brvlan1

        if [ ! -n "${VZHOSTIF}" ]; then
                echo "According to $CONFIGFILE VE$VEID has no veth interface configured."
                exit 1
        fi

        if [ ! -n "${VETH_BRIDGE}" ]; then
           echo "According to $CONFIGFILE VE$VEID has no veth VETH_BRIDGE configured."
           exit 1
        fi

        echo "Adding interface ${VZHOSTIF} to VETH_BRIDGE ${VETH_BRIDGE} on VE0"

        /usr/sbin/brctl addif ${VETH_BRIDGE} ${VZHOSTIF}
        /sbin/ip link set ${VZHOSTIF} up

fi

exit 0

2. And what is the order of interfaces you add to the bridge?
(for example: the first is eth1.35@eth1, then veth101.35, veth102.35 etc) And which of them cause the problem? I mean if the problem VE was the first to add?

each VE is started one by one, interface are mounted in the ordre the are appear in the NETIF parameter in the conf file.

the if which create problems is the second one.

3. Let's assume you've started several VEs and mounted NFS partition inside each of them. Please show "ip a l", "ip r l", "brctl show" from HN at that moment.
Then you can break this configuration via "ifconfig eth1.35 down" from inside the problem VE. Please, do it. And then show the previous commands from HN.

I can reproduce the bug with only 2 VEs up, so I guess it's enouph

With all VEs working well :
