Subject: [PATCH 00/29] lguest virtio PCI 1.0 adaptation.

Hi all!

	I've just spent a week changing lguest from its own custom
virtio bus to PCI, and from legacy virtio to modern (1.0).  I did this
mainly to test the Linux implementation.

The first 11 patches set up the framework for routing more traps to
the Lguest launcher, so we can intercept ioport and MMIO instructions.

Patches 12-15 implement emulation of virtio over PCI devices, and then
16-19 convert the four devices we support.  20-23 remove the obsolete
lguest bus support.

24-27 change the guest to bang the emerg_wr register (via the pci config
space MMIO accessor window) to perform early boot messages.  It's slow
and ugly, but it works.

Finally, the last two patches remove the last of the old hypercall
notification mechanism.

Cheers!
Rusty.

Rusty Russell (29):
  lguest: have --rng read from /dev/urandom not /dev/random.
