Now that we have upstream qemu people may want to avoid building this extra
code.
There is a little bit of trickery in stubdom/configure.ac to ensure that the
ioemu stubdom is only built if qemu-traditional is enabled.
libxl will return an error if a caller tries to build a domain using
qemu-xen-traditional when this support was disabled at build time. Since
qemu-xen-traditional has been historically tightly bound to the Xen releases I
don't see any value in supporting "3rd party" provision of
qemu-xen-traditional.
We also do not want/need this on ARM therefore default is on for x86 and off
otherwise.

mkheader.py doesn't cope with

Define unsigned long and long to a non-existent type on ARM so as to catch

Teach mkheader.py to cope with structs which are ifdef'd. This cannot cope
with #defines between the #ifdef and the struct definitions, so move

I'm not even sure what this thing is. Looks like some sort of Twisted Python
based frontend to xend.
Whatever it is I am perfectly sure no one can be using it. Apart from drive by
build fixes caused by updates elsewhere it has seen no real development since
2005. I suspect it was never even finished/usable.

I don't think there are any dom0's around whose kernels support only blktap1

We have defaulted to using the system libaio for a while now and I din't think
there are any relevant distros which don't have it that running Xen 4.4 would
be reasonable on.
Also it has caused confusion because it is not ever wanted on ARM, but the
build system doesn't express that (could be fixed, but deleting is the right

There's no need for xl to output these messages on HVM domain creation
to stderr by default.
Change their loglevels from XTL_INFO to XTL_DETAIL; then the messages
output by xl are the same as those for PV domain creation. These
now-silenced messages can still be seen using verbose (-v) mode.

After issuing a reset, the BSY bit is expected to be set. This is not the
case for Qemu.
In SeaBIOS.git: 580e33293244fee4556e56ecc67b8bd877f3c496
this check was even replaced with a udelay(5), as enough real hardware ignored
the BSY bit as well.
As rombios does not have an equivalent udelay(), replace the wait with a write
to port 0x80 which is whitelisted by Xen for 'a small delay'.
This causes 42k fewer IO traps to Qemu.

This in effect copies similar logic from xend: While there's no way to
check whether a device is assigned to a particular guest,
XEN_DOMCTL_test_assign_device at least allows checking whether an
IOMMU is there and whether a device has been assign to _some_
guest.
For the time being, this should be enough to cover for the missing
error checking/recovery in other parts of libxl's device assignment
paths.
There remains a (functionality-, but not security-related) race in
that the iommu should be set up earlier, but this is too risky a
change for this stage of the 4.3 release.
This is a security issue, XSA-61.
