[one-users] managing images

[Daniel.MOLDOVAN at cs.utcluj.ro]

Hy,
The target is the virtual target for the virtual disk. I have no used the
images repository until now and i am using KVM so i'm not entirely sure
what DISK types XEN supports . However, this might be useful so : using an
already existing virtual machine virtual disk i declare

DISK   = [
   type = disk,
   clone=no,
   size =4096,
   format = ext3,
   source= "virtualDiskFilePath",
   target   = hda,
   readonly = "no"
   ]
. Then, i have in the OS section
OS     = [
   boot = hd,
   ROOT = hda
  ]
Note that hda is just the target inside the virtual machine.

And for booting a XEN kernel located on the Host computer, NOT in the
virtual machine, use
OS     = [
   boot = hd,
   ROOT = hda,
   kernel = "/boot/vmlinuz-2.6.35-22-server",
   initrd = "/boot/initrd.img-2.6.35-22-server",
  ]
where "boot/vmlinuz-2.6.35-22-server" should be replaced by the path to
your kernel and its name,
as shown in http://opennebula.org/documentation:rel2.0:template OS section.

Hope this helps.

Regards
