When `opcontrol --shutdown' is called after xenoprof is used on Dom0,
the vpmu owner becomes PMU_OWNER_NONE. So it is possible to acquire
the owner as PMU_OWNER_HVM and to allocate vpmu->context twice. As a
result, the hypervisor panics because of double-alloc/free of
vpmu->context.

xen-setup runs the upstream configure script, and ends up
autodetecting various properties of the host and then trying to use
them in stubdom, which works badly.
In commit c609854fe18aab3216f28e1e5291b75970d398d5 in
qemu-xen-unstable we provide a new `xen-setup-stubdom' script, which
hardcodes the relevant answers.
With these two changes, stubdom should compile again.

Remove some unused variables and replaces read and write
to the pipe with read_exact and write_exact (these two functions are
implemented in libxc, that we have to link anyway).
This allows fs-backed to be compiled with -D_FORTIFY_SOURCE=2, hence
should fix the problems reported by Boris.

By default, we enable snoop control, queued invalidation and interrupt
remapping if all VT-d engines support them, and for DMA passthrough we
don't enable it by default.
A user can use 'iommu=passthrough' to enable DMA passthrough (only
for Dom0). A user can use 'iommu=no-snoop,no-qinval,no-intremap' to
disable the 3 features.

Rather than use "0x0" to signify that the hotplug slot should
be automatically selected by qemu-dm, define AUTO_PHP_SLOT_STR.
At the same time, change the magic value form 0x0 to 0xff,
in line with changes made to qemu-dm to allow any unused PCI
device to be used for hotplug.

When a udev event is received, udevevent.py parses the udev data and

Until now the udev script for blktap devices needs to decide if to
signal success or failure to xend. As this script runs completely
independent of blktapctrl and tapdisk/ioemu which do the real work,
the udev script can't even theoretically know if tapdisk is happy.
This patch removes the udev script and replaces its checks by new
ones in libblktap.

Connections to ioemu have single_handler set, so they are closed as
soon as all images of a certain type are closed. This is wrong with
ioemu: All images that belong to the same domain are handled by the
same backend process (usually qemu-dm, but also tapdisk-ioemu for
domains without device model), regardless of the image type.
This patch checks for the same-domain condition for ioemu connections.

Currently all disk types that are supported are defined in a header
file private to blktapctrl and tapdisk. When restoring ioemu as a

This patch adds support for specifying the backend (tapdisk or ioemu)
to blktapctrl. Images can be specified e.g. as tap:tapdisk:aio,
tap:ioemu:qcow2 or tap:vmdk. When omitting the backend, a default is
chosen based on the image type (currently always tapdisk because ioemu
as a backend is broken until a follow-up patch series against qemu-xen
is applied)
