[one-users] Problem with ebtables-kvm script.

Wed Nov 25 06:02:04 PST 2009

Hi all,

I update my installation to the last 1.3.90 openNenbula version, and I'm trying to give some public Ip to my VM. using Bridged networking and the scripts 
included in the last release.

But I have a problem with this script:
/srv/cloud/one/share/hooks/ebtables-kvm

This is the log I have:

I also had a go changing the assignation of argv[0] to argv [1] inside the script, but it didn't work.

This are some information about my host configuration:

I configured an OpenNebula (v 1.3.90) front-end in my pc "solaris" (Ubuntu 9.04) and installed a cluster node "omii001" (Scientific Linux CERN SLC
release 2.6.18-164.6.1.el5 x86_64).
I need to access my VM through ssh, so I used the Bridged networking("shared physical device") following this instructions:
http://www.opennebula.org/doku.php?id=documentation:rel1.4:nm

oneadmin at omii001$ brctl show
bridge name	bridge id		STP enabled	interfaces
br0		8000.0015c5edbf17	no		vnet0
							eth0
virbr0		8000.000000000000	yes	

Setting ifcfg-eth0 and ifcfg-br0 in this way:

oneadmin at omii001$ cat /etc/sysconfig/network-scripts/ifcfg-eth0
# Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet
DEVICE=eth0
BOOTPROTO=static
DHCPCLASS=
HWADDR=00:15:C5:ED:BF:17
IPADDR=131.154.100.175
NETMASK=255.255.255.0
ONBOOT=yes
BRIDGE=br0

oneadmin at omii001$ cat /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE=br0
TYPE=Bridge
BOOTPROTO=dhcp
ONBOOT=yes
DELAY=0

And this is the template of the VM:

#---------------------------------------
# VM definition example
#---------------------------------------
NAME	= two
CPU	= 1 
MEMORY	= 512
# --- kernel & boot device ---
OS	= [ boot   = hd]
# --- 1 disks ---
DISK	= [
	source   = "/srv/cloud/one/images/debian5.img",
	target   = "vda",
	readonly = "no" ]
# --- I/O ---
GRAPHICS= [
        type    = "vnc",
        listen  = "127.0.0.1",
        port    = "1"]
# --- 2 NIC ---
#NIC	= [ NETWORK = "OpenNebulaLAN",
#	BRIDGE  = "wlan0" ]
NIC     = [ NETWORK = "PublicVLAN",
        BRIDGE  = "br0" ]
SAVE	= yes

Some other information about my configuration are in the previous mail:
http://lists.opennebula.org/pipermail/users-opennebula.org/2009-November/001202.html

If someone have some advice, I would really appreciate it.

Best regards,
Gianni.

I'm not sure if it could be related, but when I compiled opennebula I had problems with some dependencies, but anyway the installation seems to work.
( I'm sure I installed all the the software dependencies listed in the "Platform Notes 1.4" page). I also read some other people had the same issue in the past, but I
cannot find the solution and neither any package for Ubuntu that satisfies the requirements.
