[one-users] SSH error

[Javier Fontan]

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" ]
