Hi all,
I am using 5 VEs based on "centos-4-i386-minimal" template. I needed broadcast and I didn't care much about security so I configured my Ethernet device on each VE that I bridged on VE0: everything works fine!
Now I'd like to configure everything automatically when I run "vzctl start VEID".
Sounds like an old thread? Yes, another very similar question was asked. Installing the last version of vzctl would solve the problem. I already have the last version of the tool, however I still have a problem.
Here are a list of my problems:
- venet0 is always configured inside the VE. I removed /etc/sysconfig/network-script/ifcfg-venet0 and it still appears at the next "vzctl start": I would like to get rid of this, and I would like to setup a proper routing for vethX inside the the VE.
- it would be good if vethX could be added to vzbr0 when I run "vzctl start VEID". Is there a way to do this?
Here are the details of my configuration files:
A typical VEID.conf (without the copyright, thought)
ONBOOT="no"
# UBC parameters (in form of barrier:limit)

# CPU fair sheduler parameter

VE_ROOT="/users/home/vz/root/$VEID"
VE_PRIVATE="/users/home/vz/private/$VEID"
OSTEMPLATE="centos-4-i386-minimal"
IP_ADDRESS=""
ORIGIN_SAMPLE="vps.basic"
HOSTNAME="tcp1"
VETH="veth1,00:12:34:56:78:1A,eth1,00:12:34:56:78:1B "
Inside the corresponding VE, /etc/sysconfig/network-script/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=none
BROADCAST=192.168.7.255
HWADDR=00:12:34:56:78:1B
IPADDR=192.168.7.1
NETMASK=255.255.255.0
NETWORK=192.168.7.0
ONBOOT=yes
TYPE=Ethernet
USERCTL=no
PEERDNS=yes
IPV6INIT=no
GATEWAY=none
It is indeed parsed at startup of the VE.
However, since it also parse ifcfg-venet0, I end up with this routing:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.7.0 * 255.255.255.0 U 0 0 0 eth1
191.255.255.0 * 255.255.255.0 U 0 0 0 venet0
169.254.0.0 * 255.255.0.0 U 0 0 0 venet0
default 191.255.255.1 0.0.0.0 UG 0 0 0 venet0
Instead of this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.7.0 * 255.255.255.0 U 0 0 0 eth1
default * 0.0.0.0 UG 0 0 0 eth1
Also I would like to get rid of the line GATEWAY in /etc/sysconfig/networking inside the VE:
NETWORKING="yes"
HOSTNAME="tcp1"
GATEWAY="191.255.255.1"
Finally I don't know when to execute "brctl add vzbr0 veth1".
Any help is much appreciated 
. VE0 is a RHEL4
