Wouldn't that make managing this entire setup much easier? In the openVZ, the vzctl tool can actually run anything inside a virtual machine. For instance, we can say 'vzctl exec $vpsid ps ax', and it will return the output of the 'ps' executed inside the vps. I realize that the virtualization concept is radically different in Xen, and thus this type of communication would be non-trivial. Anyway, I would like to know the pros and cons of having a direct mechanism to communicate with the domUs. As far as I have seen, the inability to manage the domUs directly has been the ONLY drawback of xen. Thanks in advance.
