Several recent patches cleaned up 'make rpm' for the situation
when client_only is true; these were done by manual spec file
editing (since it's relatively hard to come by a RHEL 5 s390
box). Make it easier to do in the future via a simpler command
line override.
* libvirt.spec.in (client_only): Allow for override.

configure.ac:2121: You should use the Autoconf-provided 'AC_PROG_MKDIR_P' macro instead,

This patch changes virFileLoopDeviceOpen() to use the new loop-control

The VIR_FREE() macro will cast away any const-ness. This masked a

No need to open code now that we have a nice function.
Interestingly, our virStringFreeList function is typed correctly
(a malloc'd list of malloc'd strings is NOT const, whether at the
point where it is created, or at the point where it is cleand up),
so using it with a 'const char **' argument would require a cast
to keep the compiler. I chose instead to remove const from code
even where we don't modify the argument, just to avoid the need
to cast.

In commit 991270db99 I've used virDomainNetGetActualHostdev() to get
the actual hostdev from a network when removing the network from the
list to avoid leaving the hostdev in the list. I didn't notice that this
function doesn't check if the actual network is allocated and
dereferences it. This crashes the daemon when cleaning up a domain
object in early startup phases when the actual network definition isn't
allocated. When the actual definition isn't present, the hostdev that
might correspond to it won't be present anyways so it's safe to return
NULL.
Thanks to Cole Robinson for noticing this problem.
No need to check if privileged when reading hostsysinfo, since
that check was already done in libxlDriverShouldLoad(). The
libxl driver fails to load if not privileged.
Recent patches to fix handling of Ctrl-C when interacting with
ssh are not portable to mingw, which lacks termios handling.
The simplest solution is to just compile that code out, and
if someone ever appears that has a serious interest in getting
virsh fully functional even with ssh connections, they can
provide patches at that time.

Commit ba5f3c7 moved virtualBox support into libvirtd, but the spec
file was still unconditionally requesting it even when not building
the server side. Thankfully there were no ill effects for a
client_only build, as most uses of %{with_vbox} were guarded by
%{with_libvirtd}; but we might as well avoid confusion by more
closely matching the makefile.

Automake has builtin support to prevent botched conditional nesting,
but only if you use:

else !FOO
endif !FOO

As our makefiles tend to have quite a bit of nested conditionals,
it's better to take advantage of the benefits of the build system
double-checking that our conditionals are well-nested, but that
requires a syntax check to enforce our usage style.
Alas, unlike C preprocessor and spec files, we can't use indentation
to make it easier to see how deeply nesting goes.

Commit 50348e6edf reused the code to remove the hostdev portion of a

Since commit v1.0.5-56-g449e6b1 (Pull parsing of migration xml up into
QEMU driver APIs) any attempt to rename a domain during migration fails
with the following error message:
internal error Incoming cookie data had unexpected name DOM vs DOM2
This is because migration cookies always use the original domain name
and the mentioned commit failed to propagate the name back to
qemuMigrationPrepareAny.
Now that most fields of libxlDriverPrivate struct are immutable
or self-locking, there is no need to acquire the driver lock in
much of the libxl driver.
The libxlDriverPrivate struct contains an variety of data with
varying access needs. Similar to the QEMU and LXC drivers,
move all the static config data into a dedicated libxlDriverConfig
object. The only locking requirement is to hold the driver lock
while obtaining an instance of libxlDriverConfig. Once a reference
is held on the config object, it can be used completely lockless
since it is immutable.
libxlDomainGetInfo() uses the driver-wide libxl ctx when
it would be more appropriate to use the per-domain ctx
associated with the domain. Switch to using the per-domain
libxl ctx.
libxlMakeDomCreateInfo() uses the driver-wide libxl ctx when
it would be more appropriate to use the per-domain ctx
associated with the domain. Switch to using the per-domain
libxl ctx.
libxl version info is static data as far as the libxl driver
is concerned, so retrieve this info when the driver is initialized
and stash it in the libxlDriverPrivate object. Subsequently use
the stashed info instead of repeatedly calling libxl_get_version_info().
Detect early on in libxl driver initialization if the driver
should be loaded at all, avoiding needless initialization steps
that only have to be undone later. While at it, move the
detection to a helper function to improve readability.
After detecting that the driver should be loaded, subsequent
failures such as initializing the log stream, allocating libxl
ctx, etc. should be treated as failure to initialize the driver.
Create libxl_domain.[ch] and move all functions operating on
libxlDomainObjPrivate to these files. This will be useful for
future patches that e.g. add job support for libxlDomainObjPrivate.
