[Users] Passing a hint/message to a VM when it boots

[Kyrre Begnum]

Hi,
yes, using a kernel boot option would be nice, and there is an option 
for it in Ovirt, but I am not getting it to work. When i want to 
specify  a boot parameter, I also have to specify a kernel path. When i 
specify the internal kernel, the VM fails to boot. Is this supposed to 
be an "external" kernel ( like paravirtualized Xen? )
