[one-users] Problem with network

[Luca Lorenzini]

I'm starting to use Opennebula v1.2 (i cant update to 1.4 because of
university rules) and i've problems to connect to my VMs via ssh (i cant
ping them either). I put the script vmcontext.sh in /etc/init.d/ and i
linked it in /etc/rcS.d/ but without improvements. I tried using the RAW
option in the VMs' templates to use a console with virsh console command but
the parser of the template raises an error: "Error: Error parsing VM
template". This is what i put into the template:

RAW = [
 type = "kvm",
 data = '<serial type="pty"><source path="/dev/pts/2"/><target
port="1"></serial><console type="pty"><source path="/dev/pts/2"/><target
port="1"></console>' ]
]

(i tried escaping \", wrapping it with <devices></devices> tag, but without
any results)


Here my configuration:



i saw with /sbin/ifconfig that the host have a bridge named virbr0:

virbr0    Link encap:Ethernet  HWaddr 06:65:ee:bc:65:9c
          inet addr:192.168.122.1  Bcast:192.168.122.255  Mask:255.255.255.0
          inet6 addr: fe80::d8:8aff:feee:96cb/64 Scope:Link

          RX bytes:20 (20.0 B)  TX bytes:509208 (509.2 KB)


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My network template is this:

NAME = "Ranged Network"
TYPE = RANGED
BRIDGE = virbr0
NETWORK_SIZE = C
NETWORK_ADDRESS = 192.168.122.0


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My Vm Template:

  target   = "hda",
  readonly = "no",
  clone = "no"
]

NIC    = [ NETWORK = "Ranged

FEATURES=[ acpi="no" ]



~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

virsh dumpxml return:

  /sbin/ifconfig vnet1:

As you can see it has no ip address

I will appreciate your help
