I re-based them all on them all on the newer "official" OS Templates that Kir posted last month.  The new
official OS Templates have udev installed and work well no matter what additional software you install. 
Older templates would often break if udev got installed.  That is no longer the case.

How do my contributed OS Templates differ from the "official" ones:

Re: Putting DHCP server on VENET-connected node

VENET device is explicitly NOARP, so this can't be fixed.
pls use VETH

ubuntu precreated template problem

I'm having problems with the precreated 8.04-x86 template.

After setting the normal ipaddress/hostname/gateway settings and
starting the template, I get no networking.  The CentOS template works
fine, so its not my networking setup.  If I modify the
/etc/network/interfaces file to be like a typical system, networking
will restart without error, but I cannot access the network still.

The host node is Ubuntu 8.04.

Ideas? Suggestions?

Re: ubuntu precreated template problem

remove the /etc/network/interfaces.template loopback entries:

 > auto lo
 > iface lo inet loopback
 > 	address 127.0.0.1
 > 	netmask 255.0.0.0
 > 	broadcast 127.255.255.255
 > 	up ip route replace 127.0.0.0/8 dev lo

and restart the container ...

or remove entries in /etc/network/interfaces and
restart networking or ifup lo

Seem to affected all precreated debian and ubunutu distros at 
http://download.openvz.org/template/precreated/ only

RE: ubuntu precreated template problem

We have quite new a good tested standard templates for Debian Etch, Lenny, Ubuntu 8.04 - 32 and 64 bit.
See ftp://pve.proxmox.com/appliances/system/
(or http://pve.proxmox.com/appliances/system/)

FYI, all are build using the dab:

Broadcast traffic on veth interfaces

Hi people:

I'm a newbie in OpenVZ world yet. With a little help of Google and
OpenVZ wiki I understood that it's necessary to use veth instead of
venet to be able to deal with broadcast traffic in a VE. This is true,
right?
So I created the corresponding veth to my VE and attached it to a
bridge. Now my VE has an eth0 interface, it has its own IP address and
works nicely: send and receive ICMP messages (with ping), I can get
into VE trough SSH, etc.

But I can see that broadcast traffic isn't working very well yet. My
VE is running a Samba server but I can't find its netbios name (from
the HN) using nmblookup. Also from the VE I can't find any netbios
host in my network using nmblookup except the VE host itself.

I followed the steps of the wiki:
http://wiki.openvz.org/Veth#Virtual_Ethernet_devices_can_be_joined_in_one_bridge

Do I need to do anything else in my OpenVZ environment?

Kernel: 2.6.18-92.1.18.el5.028stab060.2
vzctl version: vzctl version 3.0.23

Any help would be appreciated. Thanks, bye
