Send data from hypervisor to Dom0?
...: hypervisor can share memory with Dom0 to send data,
like what the console code is doing. But this approach may waste too
much money, like 1 memory page for only 8 bytes data! That does not
look good to me.
2) Hypervisor writes data to XenStore, but I am not sure if it is
possible to do that from hypervisory layer? (Any hints for me on how
to do that, if it is possible?).
Either of the above 2 ways, hypervisor can notify Dom0 via
event-channel (This event-channel needs to be initialized when Dom0
boots up)
Anybody could give me some suggestions on this problem? All the help
are greatly appreciated :-...
