Originally libxltypes.py provided the infrastructure and libxl.idl provided the
specific types.
In 23887:a543e10211f7 libxl.idl became libxl_types.idl (to allow for
libxl_types_internal.idl) which means we now have libxl_types.FOO and
libxltypes.FOO providing different things and annoying people in tab
completion.
Rename the infrastructure as idl.

Add code to track the address of the VM generation ID buffer across a
save/restore or migrate, and increment it as necessary.
The address of the buffer is written into xenstore by hvmloader at
boot time. It must be read from xenstore by the caller of
xc_domain_save() and then written back again by the caller of
xc_domain_restore().
Note that the changes to xc_save.c and xc_restore.c are merely
sufficient for them to build.

The other integer request types which shutdown supported are not
useful. Specifically:
* "suspend" is not usable via this interface since it requires other
scaffolding, libxl_domain_suspend provides this already.
* "halt" is the same as "poweroff".
* "crash" is unused and at least Linux does not implement it. If a user
steps forward then libxl_domain_crash is trivial to add.

This provides for fields in libxl datatypes which are only present in
the C version of structures and are used only by libxl itself. This
is useful when a libxl datatype wants to contain fields which are used
by libxl internally and which are only present in the structure to
avoid additional memory allocation inconvenience.

Fix insufficient quoting between "tap-ctl list" and

The "line.split(None, 4)" needs to be a "3", because 3 splits needs to
be done to get the 4 parts. Sorry for the mixup.

insufficient quoting between "tap-ctl list" and xend/server/BlktapController.py
BlktapController splits the output into lines using \n, then each line
at each space, and finally each of these 'words' at the '=', which
fails if the filename contains spaces.
As a quick work-around, the attached patch fixes the problem for me. That is,
until tap-ctl changes it's output format.
A more permanent solution would be to add proper quoting / escaping to tap-ctl
and un-quoting / de-escaping to BlktapController.py

DRBD disk backends can be used instead of tapdisk backends for Remus.
This requires a Remus style disk replication protocol (asynchronous
replication with output buffering at backup), that is not available in
standard DRBD code. A modified version that supports this new replication
protocol is available from git://aramis.nss.cs.ubc.ca/drbd-8.3-remus
Use of DRBD disk backends provides a means for efficient
resynchronization of data after the crashed machine comes back
online. Since DRBD allows for online resynchronization, a DRBD backed
Remus VM does not have to be stopped or shutdown while the disks are
resynchronizing. Once resynchronization is complete, Remus can be
started at will.

Remove the reference from libxl_device_console. This could never have
been used from outside libxl and is only used internally to add the
primary PV console to a guest. Make an internal variant of

All usages are single bit BitFields, AKA booleans.
In general we prefer to use simple structures (e.g. without packing or
specific layouts) in the libxl API and take care of any require
structure by marshalling within the library instead of expecting users
to do so (e.g. the PCI device BDF is unpacked in the libxl API).

Language bindings would like to strongly type the domid as a separate

This patch only impacts the datatypes and autogenerated destructors, I
didn't think the churn of switching the uint32_t's through the code

The new --null option allows one to test and play with just the
memory checkpointing and network buffering aspect of remus, without
the need for a second host. The disk is not replicated. All replication
data is sent to /dev/null. This option is pretty handy when a user
wants to see the page churn for his workload or observe the latency hit
though the latter will not be accurate.

While running remus, when an error occurs during checkpointing
(e.g., timeouts on primary, failing to checkpoint network buffer
or disk or even communication failure) the domU is sometimes
left in suspended state on primary. Instead of blindly closing
the checkpoint file handle, attempt to resume the domain before
the close.

The only "translation" is to the C locale (e.g. the NUL
translation). I think it very unlikely we are going to see any new
translations of the XenAPI error messages at this point so the only
purpose of this code appears to be to periodically regenerate
xen-xm.pot with a new embedded timestamp, to the detriment of those of
us who use a version control system.
After much beating with sticks I mananged to enable XenAPI support in
xend and configure xm such that it returns "Permission denied." (AKA
the SESSION_AUTHENTICATION_FAILED message) which I take to be a sign
I've not broken things too badly.

In particular if binary A uses libB and libB uses libC entirely
internally then A does not need to link against libC only libB.
However when linking binary A the linker does need to have visibility
of the libraries which libB links against (libC in this example). For
out of tree uses this is achieved without fuss due because the
libraries are installed in a standard path. However in the case of
in-tree users the linker needs a hint in the form of the -rpath-link
option. Therefore a new class of build variable, $(SHLIB_FOO), is
introduced which includes the linker options needed to link against a
library which uses libFOO. The intention is that $(LDLIBS_bar) will
include the $(SHLIB_foo)s which it uses where necessary rather
requiring that users are aware of this.
For the python extensions this change appears particularly large since
previously each of python bindings were linked against the union of
all possible libraries used by all bindings instead of just what they
individually needed.
This change removes a dependency on libdl.so from nearly everything
in the system, only libxenctrl actually uses it.
In the context of xl/libxl the intention of libxl is to remove any
need for a user of libxl to know about libxenstore or libxenctrl,
however in the current build it is xl which links against those
libraries rather than libxl (which only links against libc). After
this change libxl correctly depends on the libraries it uses and xl
does not depend on libraries which it is not support to be required to
know about. Note that xl does depend on libxenctrl.so since it uses
xtl_* directly.

Currently we pile all the backend and format information pertaining to
disk option in a single enum. This check-in separates the two and
uses two enums, one for disk format and another for disk backend.
This helps clearly differentiate between disk format and backend
within the implementation and also helps cleanup the code in this area
in preparation for the impending parser revamping to be done post 4.1.
Along with separating format and backend, this check-in also removes
unwanted types and renames variables in the disk interface and fixes
the code affected by the interface changes.
In specific, here are the disk interface changes made - In
libxl_device_disk structure physpath was renamed to pdev_path,
virtpath was renamed to vdev, phystype was removed and replaced with
backend and format enums. Also previously a single enum
libxl_disk_phystype held the values for qcow, qcow2, vhd, aio, file,
phy, empty and that got refactored into two enums, libxl_disk_format
to hold unknown, qcow, qcow2, vhd, raw, empty and libxl_disk_backend
to hold unknown, phy, tap and qdisk.
