75235a52bc Ensure root filesystem is recursively mounted readonly
If the guest is configured with

    <filesystem type='mount'>
      <source dir='/'/>
      <target dir='/'/>
      <readonly/>
    </filesystem>

Then any submounts under / should also end up readonly, except
for those setup as basic mounts. eg if the user has /home on a
separate volume, they'd expect /home to be readonly, but we
should not touch the /sys, /proc, etc dirs we setup ourselves.

Users can selectively make sub-mounts read-write again by
simply listing them as new mounts without the <readonly>
flag set

    <filesystem type='mount'>
      <source dir='/home'/>
      <target dir='/home'/>
    </filesystem>

a48838ad2e Fix launching of VMs on when only logind part of systemd is present
Debian systems may run the 'systemd-logind' daemon, which causes the
/sys/fs/cgroup/systemd  mount to be setup, but no other cgroup
controllers are created. While the LXC driver considers cgroups to
be mandatory, the QEMU driver is supposed to accept them as optional.

We detect whether they are present by looking in /proc/mounts for
any mounts of type 'cgroups', but this is not sufficient. We need to
skip any named mounts (as seen by a name=XXX string in the mount
options), so that we only detect actual resource controllers.

621849383a Fix polkit permission names for storage pools, vols & node devices
The polkit access driver used the wrong permission names for checks
on storage pools, volumes and node devices. This led to them always
being denied access.

The 'dettach' permission was also mis-spelt and should have been
'detach'. While permission names are ABI sensitive, the fact that
the code used the wrong object name for checking node device
permissions, means that no one could have used the mis-spelt
'dettach' permission.

cf83adfb7d build: require libnl-3 if netcf uses it
Commits 9298bfb and f6c2951 both tried to make it possible to
select the correct libnl (1 vs. 3) according to what netcf
used, when both libraries are installed.  This works to avoid
libnl-3 when netcf used libnl-1.  But on the converse side, if
only libnl-1 development code is installed, while netcf uses
libnl-3, then configure happily uses libnl-1 anyways, leading
to a test failure:

$ VIR_TEST_DEBUG=1 ./virdrivermoduletest
TEST: virdrivermoduletest
 1) Test driver "network"                                             ... OK
 2) Test driver "storage"                                             ... OK
 3) Test driver "nodedev"                                             ... OK
 4) Test driver "secret"                                              ... OK
 5) Test driver "nwfilter"                                            ... OK
 6) Test driver "interface"
... lt-virdrivermoduletest: route/tc.c:973: rtnl_tc_register: Assertion
`0' failed.
Aborted

It's much nicer to prevent this at configure time, by requiring that
if we know what netcf used, then we want the same libnl version.  As
before, this can be bypassed by someone who knows what they are doing
by setting LIBNL_CFLAGS (perhaps useful to the rare person where the
build box has a different version of netcf than the installation box).

* configure.ac (LIBNL): If we can prove netcf used libnl-3, then
don't let configure succeed with libnl-1.

f92c7e31fc build: fix regression in requiring yajl for new enough qemu
Jonathan Lebon reported an issue to me off-list about his build
failing to use qemu because he failed to install yajl-devel.  But
I recalled specifically tweaking configure.ac to die in that
situation (commits 350583c, ba9c38b).  After a bit more
head-scratching, we found the cause of the regression: commit
654c709 rearranged things so that the qemu version check now
occurs before AC_ARG_WITH has had a chance to set either
$with_qemu or $with_yajl.

Coincidentally, this fix aligns with a documentation patch that
was just posted to the autoconf mailing list :)

012c25e88c build: use library rather than cross-directory compilation
If we use subdir-objects with automake, any reference to a
cross-directory .c file will result in automake creating
rules that track dependency in the cross directory.  But this
presents a problem during 'make distclean' - if the cross
directory is cleaned up first, then the daemon directory will
be left with dangling references to .Po dependency files that
no longer exist.

Meanwhile, referring to the cross-directory .c file means
that we are compiling the file twice - once in src, and once
in daemon.  Better is to compile just once in src into a
convenience library, and then use that library from daemon.

The tests directory had a similar situation of a cross-directory
.c file; to solve that, we actually need a convenience library.

(libvirtd_LDADD): ...and instead use library.

073e157533 build: avoid $(srcdir) in *_SOURCES
Trying to enable automake's subdir-objects option resulted in
the creation of literal directories such as src/$(srcdir)/remote/.
I traced this to the fact that we had used a literal $(srcdir)
in a location that later fed an automake *_SOURCES variable.
This has also been reported as an automake bug:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13928
but it's better to fix our code than to wait for an automake fix.

Some things to remember that affect VPATH builds, and where an
in-tree build is blissfully unaware of the issues: if a VPATH
build fails to find a file that was used as a prereq of any
other target, then the rule for that file will expand $@ to
prefer the current build dir (bad because a VPATH build on a
fresh checkout will then stick $@ in the current directory
instead of the desired srcdir); conversely, if a VPATH build
finds the file in srcdir but decides it needs to be rebuilt,
then the rule for that file will expand $@ to include the
directory where it was found out-of-date (bad for an explicit
listing of $(srcdir)/$@ because an incremental VPATH build will
then expand srcdir twice).  As we want these files to go into
srcdir unconditionally, we have to massage or avoid $@ for any
recipe that involves one of these files.

Therefore, this patch removes all uses of $(srcdir) from any
generated file name that later feeds a *_SOURCES variable, and
then rewrites all the recipes to generate those files to
hard-code their creation into srcdir without the use of $@.

* src/Makefile.am (REMOTE_DRIVER_GENERATED): Drop $(srcdir); VPATH
builds know how to find the files, and automake subdir-objects
fails with it in place.
(LXC_MONITOR_PROTOCOL_GENERATED, (LXC_MONITOR_GENERATED)

d047b2d983 qemu: don't leak vm on failure
Failure to attach to a domain during 'virsh qemu-attach' left
the list of domains in an odd state:

$ virsh qemu-attach 4176
error: An error occurred, but the cause is unknown

$ virsh list --all
 Id    Name                           State
----------------------------------------------------
 2     foo                            shut off

$ virsh qemu-attach 4176
error: Requested operation is not valid: domain is already active as 'foo'

$ virsh undefine foo
error: Failed to undefine domain foo
error: Requested operation is not valid: cannot undefine transient domain

$ virsh shutdown foo
error: Failed to shutdown domain foo
error: invalid argument: monitor must not be NULL

It all stems from leaving the list of domains unmodified on
the initial failure; we should follow the lead of createXML
which removes vm on failure (the actual initial failure still
needs to be fixed in a later patch, but at least this patch
gets us to the point where we aren't getting stuck with an
unremovable "shut off" transient domain).

While investigating, I also found a leak in qemuDomainCreateXML;
the two functions should behave similarly.  Note that there are
still two unusual paths: if dom is not allocated, the user will
see an OOM error even though the vm remains registered (but oom
errors already indicate tricky cleanup); and if the vm starts
and then quits again all before the job ends, it is possible
to return a non-NULL dom even though the dom will no longer be
useful for anything (but this at least lets the user know their
short-lived vm ran).

failure to obtain job.

2b1ef11c6c qemu: recognize -machine accel=kvm when parsing native
In Fedora 19, 'qemu-kvm' is a simple wrapper that calls
'qemu-system-x86_64 -machine accel=kvm'.  Attempting
to use 'virsh qemu-attach $pid' to a machine started as:

qemu-kvm -cdrom /var/lib/libvirt/images/foo.img \
 -monitor unix:/tmp/demo,server,nowait -name foo \
 --uuid cece4f9f-dff0-575d-0e8e-01fe380f12ea

was failing with:
error: XML error: No PCI buses available

because we did not see 'kvm' in the executable name read from
/proc/$pid/cmdline, and tried to assign os.machine as
"accel=kvm" instead of "pc"; this in turn led to refusal to
recognize the pci bus.

Noticed while investigating https://bugzilla.redhat.com/995312
although there are still other issues to fix before that bug
will be completely solved.

I've concluded that the existing parser code for native-to-xml
is a horrendous hodge-podge of ad-hoc approaches; I basically
rewrote the -machine section to be a bit saner.

4e0ba0bd05 libxl: Compile regular expression where it is used
The regular expression used to determine guest capabilities
was compiled in libxlCapsInitHost() but used in libxlCapsInitGuests().
Move compilation to libxlCapsInitGuests() where it is used, and free
the compiled regex after use.  Ensure not to free the regex if
compilation fails.

8818376889 Don't call regfree() if regcomp() fails
POSIX states that the preg parameter to regcomp() is undefined on
failure, so no need to call regfree() in these cases.

12509c7999 spec: make client-only testing easier
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.

1ac24b3bac build: shut up automake warnings
I'm tired of seeing screenfuls of messages like these when using
automake 1.13 (Fedora 19):

configure.ac:2121: warning: The 'AM_PROG_MKDIR_P' macro is deprecated, and its use is discouraged.
configure.ac:2121: You should use the Autoconf-provided 'AC_PROG_MKDIR_P' macro instead,
configure.ac:2121: and use '$(MKDIR_P)' instead of '$(mkdir_p)'in your Makefile.am files.
daemon/Makefile.am:19: warning: 'INCLUDES' is the old name for 'AM_CPPFLAGS' (or '*_CPPFLAGS')

seeing as how we MUST use those constructs for the benefit of
automake 1.9 (RHEL 5).  Conversely, RHEL 5 automake complained:

aclocal:configure.ac:36: warning: macro `AM_SILENT_RULES' not found in library

Obviously, I tested this patch on both Fedora 19 and RHEL 5.

* configure.ac (AM_INIT_AUTOMAKE): Avoid obsoletion warnings.
(AM_SILENT_RULES): Avoid unknown macro warning.

9ba230d4f2 Use loop-control to allocate loop device.
This patch changes virFileLoopDeviceOpen() to use the new loop-control
device to allocate a new loop device.  If this behavior is unsupported
we fall back to the previous method of searching /dev for a free device.

With this patch you can start as many image based LXC domains as you
like (well almost).

66ec11ade4 Ensure 'arch' is always set in cpuArchNodeData
The s390, ppc and arm CPU drivers never set the 'arch' field
in their impl of cpuArchNodeData. This leads to error messages
being reported from cpuDataFree later, due to trying to use
VIR_ARCH_NONE.
