hi, who can help me?


Running OpenNebula (Frontend-Host): 
 Start opennebula as oneadmin user:

one start
onehost create node1 im_xen vmm_xen tm_nfs
onevnet create vm_lan.template
onevnet show "VM LAN"


    # do this just once a time
cd /srv/cloud/images
dd if=/dev/zero of=debian_disk.img bs=1024k seek=20480 count=0


onevm create vm_instance.template
onevm show debian
# here is the problem

define the virtual network

Before we create a virtual machine, we have to define the virtual network. This is done by creating a template file, e.g. vm_lan.template, which should contain something like:

 
NAME = "VM LAN"
TYPE = RANGED


BRIDGE = br0 # Replace br0 with the bridge interface from the cluster nodes


NETWORK_ADDRESS = 192.168.2.128
# Replace with corresponding IP address
NETWORK_SIZE    = 126
NETMASK         = 255.255.255.0
GATEWAY         = 192.168.2.108
NS              = x.x.x.x
# is this ok?
 
define a virtual machine (as oneadmin user):        vi /srv/cloud/one/etc/vmm_sh/vmm_sh_xen.conf


CPU = 0.5
MEMORY = 256

 
OS     = [ KERNEL="/boot/vmlinuz-2.6.26-1-xen-amd64", INITRD="/boot/initrd.img-2.6.26-1-xen-amd64" ]
# , kernel_cmd="ro" 
# , root="sda5"
# these two attributes are optional for xen, so i comment them out. is this ok?


CREDIT = 256

 
 define a virtual machine:


vi /srv/cloud/one/vm_instance.template
NAME   = debian
CPU    = 1
MEMORY = 512


# Disks & NICS
OS = [ boot = "cdrom" ]


 
# Define your main disk as usual, and tell OpenNebula to keep the changes.
DISK = [
TYPE = "disk",
SOURCE   = "/srv/cloud/images/debian_disk.img",
TARGET   = hda,
CLONE   = "no" ]
# this assumes that you have a plain file for debian_disk.img (e.g.
with a dd).
# is this right?


# Define an additional DISK for the ISO image with the installation CD
DISK   = [
TYPE = "cdrom",
SOURCE = "/srv/cloud/images/debian-506-amd64-netinst.iso",
TARGET = hdb,
CLONE   = "no" ]


# swap, sdd
