for shortrun i am transfering manually .. but for long run if we have
the possibility to register kernel and initrd as well like we do in euca
, that will be great.. may be something to be added in wish list.

That is possible but that will lead to huge amount of hacks as you
have to do this (at least):
* Parse the deployment.0 file or call back to opennebula to ask for
the source kernel/initrd files. TM knows nothing about kernel/initrd
* Rewrite the deployment.0 file to point to the newly copied
kernel/initrd in the node
* Take care somewhere in the stack to copy the kernel/initrd file for
livemigration (it wont work without shared storage anyway)
Why don't you just use pygrub?
OS = [ bootloader = "/usr/bin/pygrub" ]

what about extending tm driver for ssh which copy the needed kernel
alongwith images to node ?

Hi Zeeshan
You MUST put the kernels in all the nodes. You can use the parallel-scp
stuff or export them to all the nodes by NFS... It is your decision... The
concrete mechanism is not the matter... The important stuff is to make
kernels accessible by all the physical nodes....

Hi Ruben ,
thanks for answer ,
But if i have 10 kernels and 10 nodes , is there any easy way to transfer
kernels beside NFS ..
in Eucalyptus we can upload kernel and initrd alongwith image in
repository , any way to do the same in opennebula ..?

You must copy the kernel on the correct path to every physical nodes....
You can use a tool like parallel-scp (
http://code.google.com/p/parallel-ssh/ ) for do this... (perhaps your distro
have a package for parallel-ssh)
Other possibility is use full virtualization and not
paravirtualization....

In my vmtemplate it has kernel =
"/srv/cloud/one/ttylinux-xen/vmlinuz-xen",
initrd = "/srv/cloud/one/ttylinux-xen/initrd.gz",
Now as i am using SSH (with out NFS) on Nodes the location
/srv/cloud/one/ttylinux-xen does not exist since I only untar it on Front
End.
Am I missing something ?
Thanks in advance.
