[one-users] FW: Problem in deploying a VM

[Harishbabu Nagaraj]

Hi Javier,
        Find the VM description file as below, Let us know if there is any mistake in this.

NAME   = vm-example
CPU    = 0.5
MEMORY = 128
OS     = [
  kernel   = "/boot/vmlinuz-2.6.27.7-9-xen",
  initrd   = "/boot/initrd-2.6.27.7-9-xen",
  root     = "sda1" ]
DISK   = [
  source   = "/opt/nebula/images/Rhel_server_singlepart.img",
  target   = "sda1",
  readonly = "no" ]
DISK   = [
  type     = "swap",
  size     = 1024,
  target   = "sdb"]

NIC    = [ NETWORK = "Public VLAN" ]

Thanks,
Harish

Hello,

Can you send me the VM description file you are sending to ONE. I
think that the device specification is wrong but I have to check it.

Bye
