Since xen-3.3 an official unplug protocol for emulated hardware is
available in the toolstack. The pvops kernel does the unplug per
default, so it is safe to do it also in the drivers for forward ported
xenlinux.
Currently its required to load xen-platform-pci with the module
parameter dev_unplug=all, which is cumbersome.
Also recognize the dev_unplug=never parameter, which provides the
default before this patch.

These drivers provide paravirtualised drivers for pre-PVops Linux
kernels which have the classic-Xen patches applied. They do not work
with kernels which are not patched with the classic-Xen patches. In
particular this includes all PVops kernels.
For 2.6.36 and newer you should use the "PVHVM" functionality which is
available in the mainline kernel.
To build do one of:
./mkbuildtree [<arch>]
NB. You can override paths to Xen sources and a (stub) XenLinux
build tree via the XEN and XL environment variable.
- or -
make -C /path/to/kernel/build M=$PWD modules
NB. This is your native kernel build tree (or a distro provided
stub), not the XenLinux sources referred to in step 1.
NB. If you are cross compiling, you need to set ARCH and
CROSS_COMPILE too.
You get four modules, xen-platform-pci.ko, xen-vbd.ko, xen-vnif.ko and
xen-balloon.ko. Load xen-platform-pci first, and then
whichever of xen-vbd, xen-vnif and xen-balloon.ko you happen to need.
