happens.

[RFC 0/2] virtio: provide a way for host to monitor critical events in the device
As it was discussed recently, there's currently no way for the guest to notify
the host about panics. Further more, there's no reasonable way to notify the
host of other critical events such as an OOM kill.

[PATCH 0/8] lguest
As promised to Andrew, and with much thanks to Andi Kleen for feedback,
this is the new series of lguest patches.
Main change is the move to drivers/lguest (for future non-i386
expansion), but lots of cleanups driven by Andi's feedback and the
documentation effort (which made me examine every line of code).
It's not perfect, but it's definitely useful.
Cheers,
Rusty.

So this time I'm trying something different, using a bit of
