 You can use different kernels for different domains.
 Each active domain should specify its own kernel image using the --vmlinux 
option in the opcontrol command.
 That means you need to have the image available in the domain file system 
(normally this is not required as the guest image is loaded from dom0 file 
system)
 Also remember that the samples from a domU guest will not be reported in 
dom0. You need to run opreport in each guest to obtain their samples.
