[one-users] problems installing vm - could not find filesystem '/dev/root'

Sun Jul 10 00:02:21 PDT 2011

I came across a mail list with an issue similar to mines at the 
following URL: 
http://lists.opennebula.org/pipermail/users-opennebula.org/2009-April/000364.html

I can't seem to get a vm up and running, my error when the console to 
the vm:

Scanning logical volumes
   Reading all physical volumes.  This may take a while...
   No volume groups found

   Volume group "VolGroup00" not found

The vm seems to be at an unknown state when running the onevm top 
command.

My template is as follows:

CPU    = 0.1
MEMORY = 64

OS      = [
         KERNEL  = "/boot/vmlinuz-2.6.18-238.12.1.el5xen",
INITRD  = "/boot/initrd-2.6.18-238.12.1.el5xen.img" ]

DISK   = [ IMAGE_ID = 12,
   target   = "hda",
   readonly = "no" ]

DISK   = [
  type     = swap,
  size     = 5120,
  target   = sdb ]

DISK   = [
  type     = fs,
  size     = 4096,
  format   = ext3,
  save     = yes,
  target   = sdc
  ]

NIC    = [ NETWORK_ID = 4 ]

FEATURES=[ acpi="no" ]

#CONTEXT = [
#    hostname    = "$NAME",
#    ip_public   = "199.115.231.13",
#    files      = "/home/oneadmin/one-templates/init.sh 
/home/oneadmin/one-templates/authorized_keys",
#    target      = "hda",
#    root_pubkey = "/home/oneadmin/one-templates/authorized_keys",
#    username    = "oneadmin",
#    user_pubkey = "/home/oneadmin/one-templates/authorized_keys"
#]

I am using the ttylinux download from the opennebula documents from: 
http://opennebula.org/documentation:rel2.2:vmg

My system consist of 1 server running inside a xen vm, I can create 
paravirtual vm's manually, however i can't seem to get this to work. 
It's a system-wide installation of opennebula 2.2-1, the system is 
2.6.18-238.12.1.el5xen #1 SMP Tue May 31 14:02:29 EDT 2011 x86_64 x86_64 
x86_64 GNU/Linux. So I basically installed opennebula on the same box as 
the hypervisor, opennebula is running along with sunstone-server and all 
the requirements of opennebula.

Here's my log file that I got when I did the command onevm create 
(test.one):

and here's my image file (image.one):

Please help me anyway you can, if you do not have time, please let me 
know if there is anyone else I can contact.

Thank you.
