[one-users] Need information on getting VM's IP address

[lalithamba.vishwanathaiah at wipro.com]

Hi Ruben,
 
Following are the templates for VNet and VM which I have submitted.
 
The VNet template is as shown below : 
 
NAME="Public VLAN"
TYPE=FIXED
BRIDGE=eth0
LEASES=[IP=10.101.102.100]
 
 
Output : onevnet show 0
 
NID               : 0
UID               : 0
Network Name      : Public VLAN
Type              : Fixed
Bridge            : eth0
....: Template :....
        BRIDGE=eth0
        HOSTNAME=10.101.102.100
        LEASES=IP=10.101.102.100
        NAME=Public VLAN
        TYPE=FIXED
....: Leases :....
IP = 10.101.102.100 MAC = 00:03:0a:65:66:64  USED = 1 VID = 0

In this case, the MAC address what formed as a combination of 

MAC_ADDRESS = MAC_PREFFIX:IP_IN_HEXADECIMAL

where MAC_PREFIX=00:03 in oned.conf

----------------------------------------------------------------------------------
The VM Template is :
 
NAME    = nodev1m
CPU      = 0.5
MEMORY   = 256
bootargs = "--entry=xvda2:/boot/vmlinuz-xen,/boot/initrd-xen"
OS       = [bootloader = "/usr/lib/xen/boot/domUloader.py"]
DISK     = [source="/home/cloud/vm-image/disk0",target="xvda", BOOT="true", read
only="no"]
NIC     = [network="Public VLAN"]
GRAPHICS = [
  type    = "vnc",
  listen  = "127.0.0.1",
  port    = "9999"]

----------------------------------------------------------------------------------
 
When xen creates the VM and boots it, DHCP assigns the IP address dynamically to Guest VM.
In this case, how do we get the IP address of Guest VM using Open Nebula ?

Thanks and Regards,
Lalithamba.

Hi,
        onevm show <VMID> should do the job. The command output, under the Template,
in the NIC attribute should show you the IP
